Carbon fiber has many characteristics such as high temperature resistance, corrosion resistance, fatigue resistance, and friction resistance. It can be widely used in aviation, aerospace, metallurgy, automobiles, electronics, machinery, medical, chemical and other fields, and is known as the "king of new materials". When carbon fiber is used as a structural material, the tensile strength of carbon fiber multifilament is an important mechanical performance index for evaluating the performance of carbon fiber, and can intuitively evaluate the quality of carbon fiber. The traditional production process of carbon fiber tensile performance test specimens has the defects of low efficiency, high labor intensity, low yield of specimens, harmful chemical components in glue and fine fibers of carbon fiber that endanger personnel health. Our SKY5101-I carbon fiber automatic impregnation winding machine successfully solved this problem.
