Problems solved by technology

But its disadvantages are: ①It is only a composite material with a two-layer structure, and the carbon fiber paper reinforcement floats on the surface of the resin without being completely covered by the resin, so it is easy to peel off from the resin material after being loaded; ②Since the carbon fiber paper reinforcement floats on the resin surface, it is easy to cause warping and deformation of the composite material; ③ because the carbon fiber paper reinforcement floats on the surface of the resin to form floating fibers, which affects the appearance of the product and limits the freedom of product design and use

Abstract

The invention discloses a carbon fiber paper reinforced thermoplastic resin sandwich composite material. The composite material is formed through compounding two resin skin layers and a core layer positioned between the two resin skin layers, every resin skin layer is a thermoplastic resin composite material layer, and the core layer is a carbon fiber paper reinforcement. The invention also discloses a preparation method of the composite material. Clamping of the carbon fiber paper reinforcement between resins is similar to the effect of steel bars in concrete, so the carbon fiber reinforcement effect of carbon fiber papers is guaranteed, the continuity and the load transmission and dispersion property of the fiber reinforcement are guaranteed, the material is isotropic, and the integral performances of the composite material are improved; and the continuously distributed carbon fibers are in favor of forming effective channels among the carbon fibers in order to well show the conductive, antistatic and electromagnetic shielding functions.

Description

technical field [0001] The invention relates to the field of functional polymer composite materials, in particular to a carbon fiber paper reinforced thermoplastic resin sandwich composite material and a preparation method thereof. Background technique [0002] Carbon fiber reinforced thermoplastic resin composites have greatly improved the application space of thermoplastic resins with their excellent reinforcement effect. Carbon fiber itself has electrical properties, and its excellent conductive function can play a huge advantage in terms of conductivity, anti-static, electromagnetic wave shielding, and energy. [0003] However, the current molding process of carbon fiber-reinforced thermoplastic resin composite materials is mostly prepared by extrusion blending, internal mixer, etc. The fibers are compatible with the resin and dispersed inside the resin, which can play a role in the fiber bearing load and transmission to a certain extent. The effect of the load. But th...
