Layup design of T-type battery box with carbon fiber reinforced composites
The safety and lightweight of new energy automobile have extraordinary significance for the sustain-able development of automotives.The research of lightweight automotive based on its safety is important for reality.The application of carbon fiber reinforced composites in the car structure is an effective way to achieve a lightweight car.The engineering elastic constants of six unidirectional single ply composites with carbon fiber volume fraction of 50%,55%and 60%were calculated via both Halpin-Tsai equation and unit cell model as the input parameters of layup.To improve the surface flexural stiffness of T-type battery box with carbon fiber reinforced composites against its deformation in service with a maximum displacement control of 1 mm,the maximum displacement and deforma-tion of the battery box were obtained by finite element analysis.The results demonstrate that only three carbon fiber composites meet the requirement of maximum displacement less than 1 mm under loading,when the volume fraction of carbon fiber is fixed and the thickness of the battery box is no more than 3.4 mm.
