Carbon fiber composite material and preparation process thereof

Abstract

The invention relates to preparation of composite materials, in particular to a carbon fiber composite material and a preparation process thereof. The process comprises the following steps of step S1,a plurality of carbon fibers penetrate through a device support II and a pulling mechanism II to be connected to a pulling mechanism I; S2, the pulling mechanism I pulls the plurality of carbon fibers to pass through the space between two injection molding mechanisms, a hole forming mechanism is inserted between the two injection molding mechanisms, two injection molding mechanisms are closed forinjection molding, and the pulling mechanism I pulls out an injection-molded carbon fiber composite pipe; and S3, a cooling mechanism cools the formed carbon fiber composite pipe. The carbon fiber composite material is the carbon fiber composite pipe, the carbon fiber composite pipe is composed of an injection molding material and carbon fibers, the injection molding material is subjected to injection molding to form the pipe, and the carbon fibers are inserted into the pipe.

Description

technical field [0001] The invention relates to the preparation of composite materials, more specifically a carbon fiber composite material and its preparation process. Background technique [0002] For example, the manufacturing method of publication number CN109518309A carbon fiber bundle and carbon fiber bundle, the invention provides even if the single fiber fineness is large, the knot strength is also high, operability, processability are also excellent carbon fiber bundle and the manufacturing method of carbon fiber bundle; the carbon fiber bundle A method for producing a carbon fiber bundle with a single fiber fineness of 1.69 dtex to 2.5 dtex, a knot strength of 298 N / mm2 or more; a knot strength of 298 N / mm2 or more, which has the following heat treatment process: The polyacrylonitrile-based precursor fiber bundle is subjected to heat treatment for more than 90 minutes and less than 150 minutes in an oxidizing atmosphere at a temperature ranging from 220 to 300 ° C;...
