Abstract

The invention relates to ceramic fiber reinforced plastic for an automobile shell and a preparation method of the ceramic fiber reinforced plastic. According to the invention, phenolic resin fibers and tetraethoxysilane are used as raw materials to prepare SiC ceramic fibers; then graphene is loaded on the SiC ceramic fibers to prepare graphene / SiC ceramic fibers; the graphene / SiC ceramic fibers is soaked into the SiC sol to prepare SiC reinforced graphene / SiC ceramic fibers; the SiC reinforced graphene / SiC ceramic fibers are spinned into a SiC reinforced graphene / SiC ceramic fiber fabric; andfinally, the ceramic fiber fabric is compounded with polycarbonate by adopting an injection molding method to prepare the ceramic fiber reinforced plastic for the automobile shell. The ceramic fiberscan improve the tensile strength and impact strength of the polycarbonate, in addition, the preparation method of the ceramic fiber reinforced plastic has no pollution to the environment and is beneficial to further popularization and application.

Description

technical field [0001] The invention belongs to the technical field of preparation of reinforced plastics, and in particular relates to a ceramic fiber reinforced plastic used for automobile casings and a preparation method thereof. Background technique [0002] At present, most of the car body shells are made of metal materials, but there are also a small number of car shells made of carbon fiber and reinforced plastics. For cars with different purposes, the shell materials are different. In recent years, non-metallic materials such as plastic or aluminum have been used more and more widely in mid-to-high-end cars. For example, the Audi A2 uses an all-aluminum body, and the front fenders of the Nissan SUV "X-Trail" are made of plastic. Yes, plastic is used in more car bumper materials. Some people think that the firmness of the body and the thickness of the steel plate determine the safety factor of the car, but the car is not simply designed according to this point of vie...
