Production process of high-performance continuous fiber thermoplastic composite material

Abstract

The invention discloses a production process of a high-performance continuous fiber thermoplastic composite material. The preparation method comprises the following steps of S1, mixing, stirring and heating raw materials by using mixing and heating equipment; S2, coating the roller surface of a hot-melt resin coating guide roller with the raw materials treated in S1 in an extrusion manner to form a hot-melt resin film layer with uniform thickness; S3, stamping the hot-melt resin film layer prepared in S2 by using stamping equipment; S4, coating the upper surface and the lower surface of a continuous fiber thermoplastic composite lattice structure core material prepared in S3 with films through film coating equipment; S5, rolling the continuous fiber thermoplastic composite material prepared in S4 by using continuous rolling and laminating equipment; S6, heating and forming the continuous fiber thermoplastic composite material prepared in S5 by using heating equipment; and S7, cutting the formed continuous fiber thermoplastic composite material by using cutting equipment.

Description

technical field [0001] The invention relates to a thermoplastic composite material, in particular to a production process of a high-performance continuous fiber thermoplastic composite material, and belongs to the technical field of thermoplastic composite materials. Background technique [0002] Continuous fiber reinforced thermoplastic (CFRTP) is a polymer matrix composite material developed in the 1970s. It consists of a thermoplastic resin matrix and continuous reinforcing fibers and a set of additives. The resin is uniformly distributed between the fibers to form The continuous phase to fix the spatial position of the fibers and transfer the load inside the material. The resin matrix endows CFRTP with excellent mechanical properties, thermal properties, processing properties and chemical corrosion resistance; continuous fibers mainly bear external loads, which determine the mechanical properties of composite materials. Carbon fiber, aramid fiber, glass fiber, etc. can b...

Problems solved by technology

The development speed of foreign thermoplastic resin-based composite materials is very fast, which has greatly exceeded the development speed of thermosetting resin-based composite materials, and has been applied in aerospace, aviation, transportation, chemical industry, electronics, electrical appliances and other fields. The mass production of composite materials is difficult, the cost is high, and it is difficult to prepare large-scale structural parts.
