What is carbon fibers and carbon fibers definition
carbon fiber, as the name implies, it not only has a carbon material, and both soft and workability
of textile fibers, a new generation of reinforcing fibers. Compared with traditional glass fiber (GF),
Young's modulus which is more than three times; it is compared with the Kevlar fiber (KF49), only
Young's modulus is about 2 times, and in an organic solvent , acids, alkali insoluble and swelling,
outstanding corrosion resistance. Some scholars in 1981 the PANbased CF soaked in alkali NaOH
solution, the time has been the past 30 years, it still maintains the fiber morphology.Carbon fiber
is made by carbonizing organic fibers and graphitizing microcrystalline graphite material obtained.
Microstructure of carbon fibers similar artificial graphite, is turbostratic structure.
Carbon fiber is an excellent mechanical properties of new materials, 1/4 of the tensile strength of
carbon fiber resin composite material is less than the proportion of its steel in 3500Mpa more
generally, is 7-9 times stronger than steel, tensile elastic modulus of 230 ~ 430Gpa also higher
than steel. Thus specific strength that is the strength of CFRP material its density can reach more
than 2000Mpa / (g / cm3) or more, and A3 steel strength only 59Mpa / (g / cm3) around, which is
also higher than the modulus than steel. Higher than the strength of the material, the smaller
component weight, higher than the modulus, the greater the stiffness of the component, in this
sense has been foreshadowed in broad application prospects of carbon fiber project.
Looking at a variety of new composite materials (such as polymer composites, metal matrix
composites, ceramic matrix composites) excellent performance, many people expected that mankind
is entering the application materials from the iron and steel era to a wide range of applications of
composite materials era.
