Abstract

The invention provides a thermoplastic composite board, and relates to the technical field of thermoplastic composite materials. The thermoplastic composite board comprises a first base plate, a second base plate is fixedly arranged on the outer surface of one side of the first base plate, and a third base plate is fixedly arranged on the outer surface of one side of the first base plate. According to the thermoplastic composite board, under the condition that the overall performance of the material is basically not greatly influenced, the application capacity of the material is expanded, theforming capacity of the material is improved, various complex structures can also adopt a scheme of thermoplastic composite materials, and the middle layer can adopt recycled materials, so that the effects of resource recycling and environmental protection, as well as the low-carbon and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to the technical field of thermoplastic composite materials, in particular to a thermoplastic composite board. Background technique [0002] At present, in the traditional thermoplastic fiber-reinforced composite sheet, it is generally a continuous fiber-reinforced composite sheet or a discontinuous fiber-reinforced composite sheet. Continuous fiber-reinforced composite panels have high performance, but the application of post-molding will be limited in many ways, and can only be used for parts with relatively simple structures. Discontinuous fiber-reinforced composite panels have a wide range of applications and can be used in complex structures, but the performance of the material is low and cannot meet high-performance applications. [0003] To sum up, the development of a thermoplastic composite sheet is still a key problem that needs to be solved urgently in the technical field of thermoplastic composite materials. Content...
