ISBN 9780323480611 Downloaded from: AbstractThis work investigates efficient ways of lightweighting vehicles structures based on Graphene Related materials (GRMs). An integration of Graphene as polymer reinforcements within composite materials for energy-efficient and safe vehicles (EESVs) is addressed with respect to some technological challenges for instance the lack of constitutive material models for high performance structural applications. Therefore, accurate material models need to be developed to support simulation of structural design for these vehicles. A multi-scale modelling of Graphene reinforced polymer composite is elaborated and using the Mori-Tanaka micro-mechanics scheme, the effective non-linear behaviour is predicted for various micro-parameters such as the aspect ratio and volume fractions. The results show an enhancement of the equivalent macro stress-strain response when the aspect ratio is low corresponding to platelets-like inclusions. Also, the volume fraction is seen to have a good improvement on the composite response. The results highlight the effect of Graphene platelets versus Carbon and Glass fibres in the design of lightweight structures with enhanced mechanical responses and by consequence a CO 2 emissions reduction.
