    Abstract: PURPOSE:To improve physical properties such as antioxidation and mechanical strength of woven cloth by forming a silicon and/or silicon carbide coating film layer on the surface of yarn of woven and knitted cloth consisting of carbon fiber. CONSTITUTION:Woven and knitted cloth consisting of carbon fiber is maintained in vapor of silicon and/or silicon carbide, then heat-treated at 1,300-2,600 deg.C and the carbon fiber yarn is silicified to give the aimed woven and knitted cloth. For example, first Si is piled on the surface of the carbon fiber yarn and reacted with the carbon fiber yarn by the successive heat treatment to form an interfacial layer consisting of SiC between Si and C (type I). Coating films of types II, III and IV are formed by heating condition, heat-treating condition and retention time thereof. Physical properties of the woven and knitted cloth consisting of the silicon-carbon conjugated fiber thus obtained are improved and the woven and knitted cloth is useful as a reinforcing base material of composite material obtained by combining the woven and knitted cloth with ceramic (glass, etc.), metal (aluminum, etc.), etc.
