Abstract

This application provides a multi-layer composite structure, a preparation method, a battery cover, and an electronic device. The multi-layer composite structure is formed by a plurality of stacked fiber layers. Each fiber layer is formed by impregnating a fiber sheet in a prepolymer solution followed by curing, and the fiber sheet in at least one fiber layer is made of a poly-p-phenylene benzobisoxazole fiber, i.e., a PBO fiber. In this way, the multi-layer composite structure may be endowed with higher strength and modulus. When the multi-layer composite structure is subjected to an impact, energy is absorbed and dissipated. Therefore, the reliability of the multi-layer composite structure in the impact is not compromised based on thickness and weight reduction, thereby providing excellent puncture resistance for the battery cover formed from the multi-layer composite structure.
