Subject(s): Abstract: Kompositers låga vikt och deras mångsidighet ger dem potential att dratiskt minska vikt och därigenom energianvändningen i framtida fordon. Bilkarosser tillverkade i kolfiberförstärkta plaster kan göras 50 % lättare än motsvarande i stål vilket leder till en energieffektivisering på 30 %. Kompositers användning i fordon hindras fortfarande av bristande kunskap rörande deras egenskaper ur ett krock- och säkerhetsperspektiv. I detta projekt ska generiska metoder för karakterisering av krockbeteendet hos avancerade textila och multifunktionella kompositer att utvecklas. Abstract: Lightness and versatility of composite materials gives them the potential to truly revolutionize the energy consumption in the automotive sector of the future. In particular, Carbon Fibre Reinforced Plastic (CFRP) bodies are about 50% lighter than steel bodies yielding a possible total energy consumption reduction of at least 30%. Moreover, the unique properties of these materials allow them to simultaneously store electric energy and carry mechanical loads, resulting in even further weight reduction in automobiles of the future. However, the use of composites in automotive structures requires an in-depth knowledge of their unique performance characteristics from crash and safety perspective, an area not fully addressed to the present date. In the project, generic experimental methods for characterisation of advanced textile and multifunctional composites are to be developed. With these test methods formulation of physically based material models and failure criteria allowing modelling of their crash behaviour in automotive structures will result.
