The continuous fiber reinforced composite material becomes a core material for the light weight of the battery shell body due to the excellent performances of light weight, high strength, flame retardance and the like.
The current continuous fiber reinforced composite material battery can body is mainly manufactured by adopting a compression molding process, but because the battery can body is generally larger in cavity height and smaller in bevel angle (draft angle) due to the requirement of enveloping a battery module and other components, the traditional simple mode of longitudinally clamping and pressurizing an upper die and a lower die is easy to cause the problems of wrinkling, fiber pulling, displacement and the like of a composite material sheet paved on the die in the process of clamping the die, so that the ideal structural design effect of a product is difficult to realize.
In addition, when the resin in the composite material is a thermoplastic resin, because of the "hot-charge cold-forming" characteristics of the thermoplastic material, to achieve the process, it is necessary to have the material or mold reach a high temperature at which the thermoplastic material melts prior to forming in order to achieve the purpose of effectively welding and plastically deforming the material. However, this is not practical in real production: the heated material is easy to cool in the process of transferring to the mould, or the heating and cooling rates of the mould are extremely low, so that the requirement of mass production cannot be met.
