A study of crushing performance of carbon fiber composite power battery tank

The lightweight design of tank is an important part of power battery system development.One of the effective lightweight means is to raise power battery energy density through the application of carbon fiber-reinforced composite material battery tank.The finite element method is used to perform numerical investigation of carbon fiber-reinforced composite material battery tank on crushing performance,stated as an example based on LS-DYNA application,given the setting method of carbon fiber-reinforced composite material and sandwich plywood layering,considering the difference of layer setting angle,investigate the target of crushing performance of carbon fiber-reinforced composite material battery tank,such as peak crushing force,mean crushing force,energy absorption,specific energy absorption characteristics,shows that the layer[0°,60°,0°,60°,0°,60°]performance is great,for the designing guide of carbon fiber-reinforced composite material power battery tank development proficiently,though the FEA application of carbon fiber-reinforced composite material battery tank.
