Problems solved by technology

The patent document (publication number: CN103101261A) discloses an environmentally friendly and recyclable carbon fiber and hemp fiber composite sheet for automotive interior parts. Fiber composition, using the high strength and high toughness of carbon fiber, overcomes some mechanical performance defects of pure hemp fiber sheet, has the advantages of low density, high strength, good formability, non-toxic and environmental protection, etc., and can be widely used in the field of automotive interior decoration , but due to the limited performance of the chopped carbon fiber itself, there is still a bottleneck in the mechanical properties of the composite sheet, which limits its application in automotive structural parts and load-bearing parts to a certain extent.

Abstract

The invention discloses a multilayer hemp / carbon fiber composite board with a hamburger structure, which has the purposes that the strength and the toughness of the composite board are improved through carbon fibers. According to the technical scheme, the composite board is prepared from a surface layer, a hemp / short carbon fiber felt layer, a carbon fiber cloth layer, a hemp / short carbon fiber felt layer and a bottom layer through a hot-mold-pressing process, wherein the surface layer and the bottom layer are formed by mixing, lapping and needling three chemical fibers namely polyester fiber, polypropylene fiber and spandex fiber respectively; each hemp / short carbon fiber felt layer is formed by mixing, lapping and needling four fibers namely short carbon fiber, hemp fiber, polyester fiber and polypropylene fiber; the carbon fiber cloth layer is single-layer knitted carbon fiber cloth subjected to surface oxidation modified treatment. The composite board is light in weight, extremely high in strength, high in moldability, good in soundproof effect and good in shock absorption, and has non-toxic and environment-friendly effects, can be used for manufacturing automotive interior parts, and can also be used for partially replacing a metal material to manufacture automotive structures and carrying parts.

Description

technical field [0001] The invention relates to a hemp fiber composite plate and a preparation process thereof, in particular to a multi-layer hemp / carbon fiber composite plate with a Hamburg structure and a manufacturing process. Background technique [0002] With the rapid development of the automobile industry, automobile materials are developing in the direction of light weight, high strength, environmental protection and recyclability. Since the composite base materials for the production of non-metallic parts of automobiles are mainly polyurethane (PU) boards, polypropylene wood powder boards and glass steel plates, etc., there are defects in the pollution of the environment by toxic chemicals. These composite materials are gradually being replaced by new fiber composite materials. Instead, the most representative is the natural hemp fiber composite material. The patent document (publication number: CN 102294853A) discloses a Hamburg-style hemp fiber board and its pre...
