Prepreg of composite materials


With the development of science and technology and the progress of society, people have higher and higher requirements for the quality of materials. Therefore, carbon fiber composites have been widely used. Because of its excellent performance, carbon fiber composites are not only used in daily life, but also have its place in the military field. The better the product, the more technical it is. We usually see the finished product, so few people know what the shape of the finished product is before. Today, Xiaobian will take you closer to carbon fiber composites.

Braided prepreg tape

At present, enterprises that can produce prepreg tapes and prepregs in China are relatively scarce, because R&D requires not only a lot of manpower but also a lot of funds. In order to better serve customers and adhere to its own R&D path, Suzhou Noen Composite Materials Co., Ltd. has finally successfully established its own prepreg and prepreg production line through the continuous efforts of researchers.

What is composite material? The standard of composite materials is mainly determined from three aspects: matrix resin, fiber and fiber morphology. What is prepreg? Prepreg is a composite of resin matrix and reinforcement made by impregnating continuous fibers or fabrics with resin matrix under strictly controlled conditions. It is an intermediate material for manufacturing composite materials. Some properties of prepreg are directly brought into the composite and are the basis of the composite. The performance of the composite depends largely on the performance of the prepreg.

Unidirectional prepreg tape

Prepreg for composite materials can be divided into the following three categories:

1、 According to reinforcement type

Carbon fiber prepreg, glass fiber prepreg, aramid fiber prepreg, other fiber prepreg

2、 According to the type of matrix resin

Thermosetting prepreg, thermoplastic prepreg

3、 According to the physical form of reinforcement

One-way prepreg, fabric prepreg

Current situation and trend of composite prepreg

Prepreg refers to the composite of resin matrix and reinforcement that can be stored by impregnating the resin matrix with continuous fibers or fabrics under strictly controlled conditions. Prepreg is the intermediate material for manufacturing composites, and its quality directly affects the quality of composites. In application, the prepreg is cured by thermal polymerization.
