Tianniao Company specializes in manufacturing carbon fiber fabric, aramid fiber fabric, preform of thermo structure material, carbon brake preform and high performance carbon/carbon compound materials. The carbon fiber quasi-3D stereo fabric manufactured with creative technology of Tianniao Company overcame the defects of pre-oxygenated fiber fabric and made up for the high cost of carbon fiber 3D weaving structure. It has such properties as layer density, uniform volume density, difficult beveling, good integral stability and easy CVD permeability. It is a typical new material with low cost and high performance. It is also an ideal reinforcement for preparing carbon resin compound materials and carbon/carbon compound materials at modern times.
