.
The main objective is to reduce the structural weight by 30% on self-supporting structures. This will be achieved by development of new cost-efficient design- and material concepts in sandwich technology.
The work will be focused on a number of demonstrators with a common need for lower weight. The demonstrators have similar requirements and many common technical challenges although they are used in different industrial sectors. These technical challenges will be addressed in the project and the resulting knowledge, methods, databases and equipment will be the basis for a Technology platform for lightweight design in sandwich technology. The Technology platform will be a powerful resource for further development of lightweight sandwich products.
The three-year project started in December 2004 and is sponsored by VINNOVA, participating industries and partners. The project
webpage is only available in Swedish.

CESAR is a 3 year IP-project with 39
partners, started in September 2006
Evektor
VUT100 Cobra is a 5 passenger aircraft to be used as an
demonstrator to develop a new roof structure in composite
material.
CESAR focuses
on small-size commercial aircraft providing manufacturers with
an enhanced ability needed to become fully competitive in the
world market. The objective is to build up a new development
concept for this aircraft category and to improve selected
technologies enabling a significant reduction of the

and maintenance costs, while considering safety, passenger
comfort and environmental impact. The project consists of five
RTD areas as described below. In particular CESAR aims at enhancing
aerodynamic and structural design tools and structural
evaluation methods. RTD work comprises development, validation
and integration of design tools and methodologies to provide
suitable environment for virtual aircraft simulation.
Enhancement of design processes, knowledge management and
collaboration tools is an essential part of the project. The activities also include the integration
of the latest technologies already applied to large commercial
aircraft and their modified economical use within the category
of small-size commercial aircraft, e.g. cost effective
actuation, complex power-plant control system, competitive
technologies for air systems, structural health monitoring and
on condition maintenance systems. Validation is carried out on
two levels: a) on the task level (hardware platforms), b) on the
project level (two baseline a/c configurations for assessment
and trade offs).

PreCarBi - Materials,
Process and CAE tools developments for
Pre-impregnated Carbon
Binder yarn preform composites
Composites are the material of choice for many advanced
aircraft structural applications (A380 28% and Boeing
787 50% content) and have proven weight/performance
superiority over metals. The critical issues today are
performance improvements, development of faster, more
cost effective manufacturing and simulation tools to
optimise their manufacture and design.
Today manufacture of advanced composites uses either
layers of pre-impregnated plies (prepregs) to form a
laminate, or resin infusion of dry textiles (Liquid
Composite Moulding LCM). Prepreg composites give
superior mechanical properties due to toughened resins
well dispersed in carefully controlled fabric
architecture, but suffer from high material costs,
limited shapeability, complex/expensive manufacturing
and limited shelf life. LCM technologies can overcome
many limitations, but must use low viscosity resins for
infusion and suffer from fibre misalignments due to
textile patterns, both of which lead to poorer
mechanical performance intolerable for many structural
aircraft applications.
The PreCarBi project will develop new materials (carbon
fibers and liquid resins) as well as supporting
technologies, already proven on a laboratory scale, that
bring together prepreg and LCM technologies to combine
the advantages of each. Essentially pre-impregnated
carbon fibres with a polymer binder formulation are
developed for LCM and tow placement processes.
Activation (e.g. heat, microwave, ultrasound) allows
binder yarns to be (repeatedly) shaped prior to resin
infusion (see enclosed figure). The binder yarns enhance
mechanical properties, due to their formulation and
ability to eliminate fibre waviness; also, they have
indefinite shelf life, improve pre-form
handling/trimming and drapeability. The combination of
superior performance and cost effective manufacture will
ensure composites growth in future aircraft leading to
improved performance, greater payloads and
fuel/emissions reductions.

DE-LIGHT Transport
“Developing lightweight modules for transport
systems featuring efficient production and lifecycle benefits at
structural and functional integrity using risk based design”
DE-LIGHT is an EC-funded
STREP-project starting November 1, 2006, and will last for 3 years.
There are 19 members and the coordinating organisation is the Center
of Maritime Technologies (CMT).
Complex lightweight modules for ships and railway will be developed
using risk based design methods. The modules will contain structural
and outfitting components. The modules can be efficiently
pre-assembled under favorable working conditions using economy of
scale. Modules can be adopted to customer needs thus featuring
structural and functional integrity, improved safety and
environmentally friendliness as well as efficient operation and
reduced life cycle cost. The development of lightweight modules will
thus contribute to increase the competitiveness of European
producers and operators of transport systems. The application of
risk based design methods will allow to develop highly innovative
solutions exceeding the range of existing classification rules by
exploring new material combinations, innovative joining, assembly
and pre-outfitting techniques. The scope of applications followed by
DE-LIGHT reaches from passenger and RoRo ships, through cargo and
short sea ships, to intermodal transport units and railway
carriages.
SICOMPs main work is in WP4E where a fully-composite cargo unit
based on lightweight sandwich technology with innovative joining
methods, parts integration and improved thermal performance will be
developed together with APC Composite. The cargo unit can be used on
rail, road and ship. The use of extremely lightweight and durable
materials offers higher load capacity and longer service life than
existing solutions. Higher load capacity improves the overall
cost-efficiency and reduces the environmental impact. Specifically,
this refrigerated unit will provide the following advantages over
the existing state of the art:
- Lightweight – up to 30%
lighter than conventional solutions.
- Durable design – an
increased service life of up to 100% with maintained properties is
expected.
- Cost efficient – higher
load capacity and longer service reduce life cycle costs.
- Modular design – a
platform concept will be used in order to reduce the number of
components whilst still being flexible for different unit sizes.

AEROSPACE NANOTUBE
HYBRID COMPOSITE STRUCTURES WITH SENSING AND ACTUATING CAPABILITIES
(NOESIS)
NOESIS is an
EC-funded STREP-project starting November 1, 2006, and lasting
for 4 years. The project consortium consists of 15 partners and
the coordinating organisation is INASCO Hellas (Greece).
The increased
use of high performance composites as structural materials in
aerospace components is continuously raising the demands in
terms of dynamic performance, structural integrity, reliable
life monitoring systems and adaptive actuating abilities. This
project exploits the unique properties of Carbon Nanotubes
(CNTs) as a matrix dopant in Fibre Reinforced Plastics (FRP),
with the aim of producing structural composites with improved
mechanical performance as well as sensing / actuating
capabilities. The development of new generation composites using
CNTs as filler material within the matrix is expected to result
in the enhancement of the damping properties of the material,
the increased fracture toughness and the improvement of its
fatigue life. At the same time, the percolated CNT network
within the composite is expected (i) to be strain sensitive and
(ii) closely related to internal damage mechanisms within the
material, providing thus the sensing and life-assessment tool
throughout the service life of the material. At the same time,
the electromechanical response of CNTs provides the field for
the design of actuating systems comprised of CNT structures of
varying degree of anisotropy that will be incorporated in the
composite. The challenge that this project is facing is to
successfully combine the CNT properties and existing sensing
actuating technologies realising a multi-functional FRP
structure.

GARTEUR Action Group 32
- Damage Growth in Composites
SICOMP participates in the European aeronautical
research collaboration within GARTEUR (Group for
Aeronautical Research and Technology in Europe). The GARTEUR work
is performed within action groups (AG) dedicated to
different scientific areas in the field of aeronautics.
SICOMP is an appreciated partner in many action groups
devoted to composite material research.
The AG32 – Damage growth in composites is a three-year
programme led by Dr Aniello Riccio, CIRA (Centro
Italiano Ricerche Aerospaziali), Italy. The work is set
out with the objective: To develop integrated
numerical/experimental methodologies capable to take
into account the presence of damage and its evolution in
composite structures from the early phases of the design
(conceptual design) up to the detailed FEM analysis and
verification phase.
The development of new methodologies to support the
composites design process towards a damage tolerance
philosophy will imply significant improvements to how
composite structures are adopted by the aerospace
industry. The work in GARTEUR AG32 is expected to result
in:
reductions in time and cost spent in design by improved,
efficient design tools
improved performance due to reduced conservatism in
future designs
reduced costs for certification as the number of
required tests is reduced
enhanced design allowables relying on a deep
understanding of the failure processes
etc.
The programme is divided into 4 technical Work Elements
(WE). SICOMP is leading WE1 Development of detailed
Methodologies. The work in this WE is devoted to
development of detailed methodologies for delamination
onset and growth as well as detailed methods for
distributed damage. In contrast WE2 is directed to the
development of fast methodologies for analyses of these
damage types. The models are to be validated in WE4 by
comparison to test data from coupon and structural tests
in WE3. SICOMP will focus its model development to
analysis of the effects of distributed damage resulting
from impact on the performance of thick laminates. This
work is performed in close collaboration with Saab
Aerostructures and Luleå University of Technology. A
part of SICOMPs work also comprises damage onset and
growth in textile reinforced composites. This work will
be communicated with EADS-M, in particular.

CASTCOMP –
Metallövergjutning på plastkomposit
Ett treårigt projekt
som startade
hösten 2006
inom VINNOVAs program "Komplexa sammansatta
produkter" .
Det är idag
ett stort problem att sammanfoga polymerer och metaller
på ett kostnadseffektivt och produktionstekniskt enkelt
sätt. Vanligtvis krävs speciella fästelement eller
limfogar för att uppnå ett hållbart förband.
Användningen av fästelement i polymera kompositmaterial
kräver till exempel att konstruktionen överdimensioneras
för att klara laster i exempelvis bultförbandet.
Infästningar i en kompositstruktur är generellt ett
problem, då dessa är besvärliga att tillverka på ett
hållfast sätt.
Syftet med
projektet är att utveckla ett nytt och innovativt
tillverkningskoncept baserat på att lättmetall
alternativt zink gjuts ovanpå en polymermatriskomposit.
Målsättningen är att ta fram en verifierad metod samt
teoretiskt analysera för- och nackdelar med
metallgjutning på komposit. Målsättningen är att metoden
efter projektavslut skall vara tillräckligt utvecklad
och utprovad för att kunna användas i framtida produkter.
För mer information,
kontakta Maciej Wysocki.
Lastbärande
kompositer
Inom detta
FoU-program bedrivs forskning och utveckling på
fiberförstärkta termoplastmaterial för lastbärande
applikationer. Programmets mål är att förbättra
kunskapen om fiberförstärkta termoplastmaterial för att
därigenom säkerställa tillförlitlig design och
kostnadseffektiv tillverkning. Speciellt fokuseras på
ökad kunskap inom textil förformingsteknik och
konsolidering.
2007 års projekt
kommer i huvudsak att bestå av tre moment:
1. Strukturella
komposita batterier 2.
Beräkningsmetoder för nya energiabsorptionsprinciper 3.
Multifunktionella Material - Teknisk Textil /
Twintexkombination
För år 2007
planeras en förstudie med att utveckla lastbärande
kompositer med integrerad batterifunktion. Målet är att
utveckla komposita material som tack vare lämpliga val
av fibrer och matris har både en lastbärande förmåga och
samtidigt fungerar som ett batteri. En sådan produkt är
av stort intresse för fordonsbranschen, då utvecklingen
mot hybridfordon vållar bekymmer med den stora mängden
batterier som krävs.
Arbetet med att
utveckla beräkningsmetoder för nya
energiabsorptionsmekanismer härstammar från ett tidigare
projekt där en komposit krockbalk utvecklats. Målet var
att utveckla en stötfångarbalk som skulle uppfylla
nuvarande personbilskrav och ge en viktsreduktion på
minst 30 % jämfört med en stålbalk. Detta uppnåddes med
en innovativ design där lastöverföring och
energiupptagning kombineras i en och samma detalj.
Införande av den nya energiupptagningsprincipen
förhindras dock fortfarande av bristen på utprovade
beräkningsverktyg.
Det finns stort
intresse för att integrera funktion hos tekniska
textilier med den lastbärande förmågan hos kompositer.
Den första uppenbara är att den tekniska textilen kan
upprätthålla en föreskriven form och även bära laster.
Den andra stora fördelen är att produkten är flexibel
under transport och konsolideras/uthärdas till den
önskade formen först på plats. Möjliga
användningsområden är till exempel presenningar, kapell,
designstolar, bilstolar, självbärande
textilljudisolering, dekorativa inredningsdetaljer,
bilinteriör, möbler samt byggmaterial som formas på
plats.

Förbättrade ytor
i SMC-produkter (FYS)
FYS är
ett tre-årigt projekt inom Programrådet För Fordonsforskning (PFF)
med projektstart 2006.
SMC är ett utmärkt material för exteriöra
fordonsdetaljer. Om tillförlitligheten vid tillverkning
av
SMC-detaljer med klass ”A” ökar kommer också
användandet av SMC hos fordonstillverkare att
öka
drastiskt och den totala kostnaden minska. FYS-projektet
innehåller en stor del av
Sveriges kompetens inom
området, vilket ger goda möjligheter att uppnå
projektets mål som är: Minskad reparation, omlackering,
kassation och kostnad.
I projektet ska följande behandlas:
-
Kunskap om hur porhalten i SMC-produkter kan minskas.
- Hur
SMC-produkter med mindre variation i mekaniska
egenskaper och felfria ytor rationellt kan tillverkas.
- Utveckling
av instrumenterad
detekteringsmetod som ersättning för manuell inspektion.
