Abstract

The invention provides a polypropylene material for forming a carbon fiber composite material as well as a preparation method and application of the polypropylene material. The polypropylene material comprises a combination of polypropylene resin, an elastomer and an antioxidant in specific parts, by adding specific parts of the elastomer and the antioxidant and matching with a specific preparation process, the polypropylene material has high toughness and high melt strength, is not easy to break and has lower extractable temperature, and a polypropylene mandrel can be obtained through blow molding and is further applied to molding of a carbon fiber composite material; and in addition, complex conditions in the forming process of the carbon fiber composite material can be borne, breakage of the polypropylene mandrel during extraction is avoided, and the preparation success rate of the carbon fiber composite material is increased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene material used for forming carbon fiber composite materials and its preparation method and application. Background technique [0002] Carbon fiber composite materials are widely used in military, aerospace, automobile and mountain bike fields due to their high specific strength, light weight, good shock absorption and corrosion resistance. However, the traditional bag pressing method has problems such as rough inner surface after molding, unstable product weight, and difficult removal of supporting parts in the process of forming hollow parts. Therefore, a new process for forming carbon fiber composite materials using PP plastic parts has been developed. [0003] CN104626602A discloses a method for forming a carbon fiber composite pipe, which includes the following steps. In the first step, carbon fibers and glass fibers are impregnated into ...
