The carbon fiber prepreg is a composite of epoxy resin on the carbon fiber through high pressure and high temperature technology.
carbon fibre
As the name implies, it not only has the inherent characteristics of carbon materials, but also has the flexibility and processability of textile fibers. It is a new generation of reinforcing fiber. Compared with traditional glass fiber (GF), Young's modulus is more than 3 times; Compared with Kevlar fiber (KF-49), it is not only about twice its Young's modulus, but also insoluble in organic solvents, acids and alkalis, with outstanding corrosion resistance. Some scholars soaked PAN-based CF in strong alkali NaOH solution in 1981. It has been more than 30 years, and it still maintains fiber morphology
epoxy resin
Epoxy resin refers to organic polymer compounds with two or more epoxy groups in the molecule. Except for a few, their relative molecular weight is not high. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the active epoxy groups in the molecular structure, they can react with various types of curing agents to form insoluble and insoluble polymers with three-dimensional network structure.
