Description

technical field [0001] The invention relates to the technical field of carbon fiber thermoplastic material preparation, in particular to a fiber thermoplastic casting vibration soaking prepreg machine. Background technique [0002] Thermoplastic composite materials have outstanding characteristics such as low density, high strength, fast processing, and recyclable reuse. They are high-performance, low-cost, and green and environmentally friendly new composite materials. Lightweight metal materials have broad application prospects in military industry, civilian use, medical treatment, sports, etc. Difficult infiltration of thermoplastic composite materials restricts the popularization and application of thermoplastic composite materials. A fiber thermoplastic casting strong infiltration prepreg machine of the present invention is a good equipment to solve the problem of difficult infiltration of thermoplastic composite materials. It has the advantages of thorough infiltration...

Problems solved by technology

Thin film preparation The use of thermoplastic film to produce thermoplastic prepreg has the advantages of simple production process and low cost. The disadvantage is that the prepared prepreg is limited by the precision and variety of the film, and the prepreg effect is very limited.

The hot-melt method is generally divided into coating and casting for conventional preparation. Its advantage is that it can obtain high resin accuracy and infiltration effect for the preparation of thermosetting carbon fiber prepregs that are easy to infiltrate. For thermoplastic materials that are difficult to infiltrate carbon fibers, there are shortcomings. Not thorough, wastes energy, and is less productive
