Since the advent of fiberglass reinforced plastic (FRP) composited with fiberglass and organic resin, carbon fiber, ceramic fiber and other reinforced composite materials have been successfully developed, the performance has been continuously improved, and the application of carbon fiber has been continuously expanded.
What is carbon fiber?
Carbon fiber is an inorganic high-performance fiber with carbon content higher than 90%, which is converted from organic fiber through a series of heat treatments. It is a new material with excellent mechanical properties. It has the inherent characteristics of carbon materials and is a new generation of reinforcing fibers Material.
Properties of carbon fiber
The tensile strength of carbon fiber is generally above 3500Mpa, and the tensile modulus of elasticity is 23000~43000Mpa. It has the characteristics of general carbon materials, such as high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance. It is anisotropic and soft, and can be processed into various fabrics, showing high strength along the fiber axis.
Application of carbon fiber
The main use of carbon fiber is to composite with resin, metal, ceramic and other matrix to make structural material.
Carbon fiber reinforced epoxy resin composites have the highest comprehensive index of specific strength and specific modulus among existing structural materials. Because of their small specific gravity, good rigidity and high strength, they have become an advanced aerospace material, and are also widely used in Sports equipment, textiles, chemical machinery and medical fields, etc.
