Thermoplastic fiber-reinforced epoxy composite and applications thereof

Abstract

The invention discloses a thermoplastic fiber-reinforced epoxy composite and applications thereof. The thermoplastic fiber-reinforced epoxy composite is prepared by taking epoxy resin and crylic acid as raw materials, thermoplastic fiber aramid woven cloths as reinforcing materials, N,N-dimethylaniline as catalyst, 4-methoxyphenol as polymerization inhibitor, trimethylolpropane triacrylate as diluted monomer, isopropylthioxanthone as photoinitiator, silane coupling agent as modifier, and metahanol as solvent, firstly synthesizing epoxy acrylate, diluting with the trimethylolpropane triacrylate, synthesizing photosensitive resin, dipping the thermoplastic fiber aramid woven cloths with the photosensitive resin, and carrying out fast forming of a novel electric car body support frame on photocuring forming equipment. The photocured electric car body support frame prepared by using the method has excellent performances, is environment-friendly, and has no harm influence on human body and ambient environment, and the curing effect meets the national standard.

Description

technical field

[0001] The invention relates to a thermoplastic fiber-reinforced epoxy-based composite material and its application. Background technique

[0002] 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 automotive structural parts is one of the most effective ways to achieve lightweight automobiles. Composite materials greatly reduce the mass of the car, which means that only less power is needed, thus providing a platform for the continuou...
