Chopped ramie fiber/carbon fiber/thermoplastic polymer composite plate

The invention discloses a chopped ramie fiber/carbon fiber/thermoplastic polymer composite plate. The composite plate is of a sandwich structure and manufactured by thermally pressing an upper surface layer, a lower surface layer and an intermediate core layer, wherein the upper surface layer and the lower surface layer are chopped ramie fiber/thermoplastic polymer sheets; and the intermediate core layer is a chopped carbon fiber/thermoplastic polymer sheet. According to the chopped ramie fiber/carbon fiber/thermoplastic polymer composite plate, the ramie fiber and the carbon fiber are correspondingly mixed with half amount of thermoplastic polymer to form sheets, and then the sheets are overlapped and pressed to form a special sandwich structure, so that the problem of difficulty in mixing of the thermoplastic polymer and plant fiber and the carbon fiber can be effectively solved; and the plant fiber and the carbon fiber can be uniformly dispersed in the thermoplastic polymer, and thus the performances of th
