Description
Technical Field
The invention relates to a carbon fiber modified material, in particular to a formula of the carbon fiber modified material and a manufacturing method thereof, belonging to the technical field of manufacturing and application of the carbon fiber modified material.
Background
The carbon fiber reinforced plastic is prepared through mixing plastic and carbon fiber short fiber in certain weight proportion in a high speed mixer, and extruding to pelletize. The method has the advantages that the density and the shape of the plastic and the carbon fiber are different, so that the plastic and the carbon fiber are not mixed uniformly, and the proportion of the carbon-containing fiber in the prepared particles is uncertain and different. Later, carbon fiber materials are used instead to enter the extruder from the side feeding machine charging barrel, but because carbon fibers are not modified, carbon fibers are fed by gravity to generate a feeding bridging phenomenon due to small volume density in the process of conveying the carbon fibers from the side feeding barrel to the extruder, so that the carbon fibers are not fed into the extruder, and the feeding bridging phenomenon means that carbon fiber short fibers are conveyed into the extruder from the charging barrel and cannot be conveyed uniformly and stably by gravity alone, but a carbon fiber material-free space is formed at the bottom of the charging barrel, and no carbon fibers enter the extruder. Therefore, a formula of the carbon fiber modified material and a manufacturing method thereof are provided for solving the problems.
