Abstract

The invention discloses a photo-curing thermoplastic fiber-reinforced epoxy composite material and a preparation method thereof. During preparing, trimethylolpropane triacrylate is taken as a diluent monomer to prepare an epoxy acrylate diluent; the epoxy acrylate diluent and a photoinitiator are mixed and heated into a liquid glue state to obtain liquid photosensitive resin; a piece of thermoplastic fiber-reinforced cloth is coated with the liquid photosensitive resin in a brushing manner, and a piece of prepreg cloth is prepared; and the prepreg cloth is paved on a forming mold and placed on UV(ultraviolet) curing forming equipment for curing forming, so that the thermoplastic fiber-reinforced epoxy composite material is obtained. The thermoplastic fiber-reinforced epoxy composite material can be used for manufacturing a novel electromobile body support frame. The novel photo-curing electromobile body support frame manufactured with the method is good in performance and environment-friendly, and has no harmful influence on a human body and surrounding environment, and simultaneously, the curing effect meets the national standard.

Description

technical field [0001] The invention belongs to the technical field of a photosensitive resin-based composite material used in an ultraviolet curing rapid prototyping method for intelligent electric vehicle body parts, and in particular relates to a light-cured thermoplastic fiber-reinforced epoxy-based composite material and a preparation method thereof. [0002] technical background [0003] The rapid development of the automobile industry has led to a sharp increase in car ownership, and at the same time brought three major problems to the society: energy shortage, environmental pollution, and safety issues. Reducing fuel consumption and reducing environmental pollution has become a key issue that needs to be solved urgently for the development of the automobile industry and the sustainable development of society. The lightweight of automobiles is one of the most effective ways to save energy and reduce pollution, and the use of composite materials to manufacture automotiv...
