Carbon fiber prepreg is a kind of material made of carbon fiber. Carbon fiber is a kind of microcrystalline graphite material obtained after carbonization and graphitization of organic fiber. Its microstructure is similar to that of artificial graphite, which is a disordered graphite structure. It not only has the inherent characteristics of carbon materials, but also has the soft processability of textile fibers. Although it is black, it can be dyed with different colors.
Carbon fiber prepreg has many advantages, such as light weight, corrosion resistance, high strength, good durability, aging resistance, and stable physical properties. It can be used together with the matching impregnating adhesive, and can become a carbon fiber composite material, which is suitable for strengthening projects such as increasing the service load of buildings, changing the use function of projects, and treating structural cracks.
Prepreg refers to the sheet product that impregnates the matrix in the reinforced fiber to make prepreg, which is an intermediate material in composite materials. The carbon fiber prepreg is specifically impregnated with resin on the surface of the carbon fiber cloth, but it is not heated for curing, so as to provide the preparation for later molding and curing. Therefore, in fact, carbon fiber prepreg is its pretreatment product.
Compared with other materials, composite materials produced by using prepreg can improve strength, corrosion resistance, lightweight, fatigue life, impact resistance, wear resistance and other characteristics, and are widely used in sports equipment, fishing gear, sports goods and other fields.

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.
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.
How to use carbon fiber cloth to prolong its service life
1. For carbon fiber cloth, the fiber stress mode shall be designed to only bear tensile stress. 2. The rear surface of carbon fiber cloth shall be protected. The surface protection material shall be harmless to the fiber and adhesive, and shall have reliable bonding strength and mutually coordinated deformation performance with the adhesive.
