Abstract

The invention discloses a PTT / carbon fiber composite material and a preparation method therefor. The PTT / carbon fiber composite material comprises the following ingredients, by weight, 75%-92% of PTT, 5%-15% of carbon fibers, 2%-6% of plasticizers, 0.5%-2% of ultraviolet ray stabilizing agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The carbon fibers are short cut polypropionitrile carbon fibers with surfaces processed in an electrochemistry polymerization method. The beneficial effects are that the carbon fibers surfaces are subjected to surface processing in an electrochemistry polymerization method, and the surface infiltration performance and reactivity are raised greatly, and thus the prepared composite material has a high specific strength and excellent crystallization orientation degree; the heat resistance and chemical resistance are good, the size is stable, the preparation technology is simple and controllable, the production cost is low, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PTT / carbon fiber composite material and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc., but PTT has poor heat resistance when used alone , Low dimensional stability and low strength limit its application.
