A brief introduction to carbon fiber prepreg

Carbon fiber products are popular used in aerospace, medical equipment, rail transportation, automotive industry and other fields, with light weight, high strength, high temperature resistance, corrosion resistance and other properties. Carbon fiber products are made of carbon fiber prepreg only. Let's take a look at carbon fiber prepreg.

Carbon fiber prepreg is done by compounding the epoxy resin on carbon fiber through high-pressure and high-temperature technology. The composite material processed by carbon fiber yarn, epoxy resin, release paper and other materials through coating, heat pressing, cooling, coating, winding and other processes is called carbon fiber prepreg, also known as carbon fiber prepreg cloth . The product types of carbon fiber prepreg includes unidirectional carbon fiber prepreg and woven carbon fiber prepreg. Unidirectional carbon fiber prepre  have the greatest strength in the fiber direction. They are usually used in laminated carbon plates with different combinations of directions(usually 0 degree and 90 degree layers), while woven carbon fiber prepreg has different weaving methods(twill weave and plain are most common). Its strength is approximately equal in all directions and can be applied to different structures.

The density of carbon fiber prepreg is generally 1.7g / cm3, which is 60% of the traditional weight-loss material aluminum alloy, less than 1/4 of steel, and the weight loss performance is outstanding. At the same time, the mechanical properties of carbon fiber prepreg are also very prominent. The tensile strength of T300 carbon fiber prepreg can reach 3500MPA. The comprehensive index of specific strength and specific modulus is better than most structural materials, and also has excellent bending strength and shear strength, which can effectively meet the needs of service strength. It is a light-weight, high-strength high-performance material.
