Abstract

The invention relates to the technical field of carbon fiber composites, in particular to a method for preparing a carbon fiber composite without vacuum bags or autoclaves. The method for preparing the carbon fiber composite without the vacuum bags or the autoclaves comprises the following steps of 1, material preparation; 2, cutting; 3, vacuum belt conveying; 4, hot press molding; and 5, demolding and cooling. Hot press molding is directly conducted through a vacuum silica gel mold, and furthermore, the vacuum bags and the autoclaves do not need to be used; furthermore, the complex process ofthe prior art that packaging is conducted through the vacuum bags, so that time is consumed is avoided; and therefore, the method for preparing the carbon fiber composite without the vacuum bags or the autoclaves has the advantages of being simple in process and high in production efficiency. The method for preparing the carbon fiber composite without the vacuum bags or the autoclaves has the beneficial effects of being simple in method, low in production cost and applicable to large-scale production.

Description

technical field [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a method for preparing carbon fiber composite materials in an autoclave-free vacuum bag. Background technique [0002] Carbon fiber is an inorganic high-performance fiber with a carbon content higher than 90%, which is transformed from organic fibers through a series of heat treatments. It is a new material with excellent mechanical properties. It has the inherent characteristics of carbon materials and has the softness of textile fibers. Processability, is a new generation of reinforcing fibers. The carbon fiber composite material is a composite material made by compounding reinforced fibers such as ceramic fibers and boron fibers on a carbon fiber base material. [0003] At present, the application of carbon fiber composite materials is more and more extensive. However, in the prior art, the preparation of carbon fiber composite materials generally ne...
