INORGANIC FIBER FABRIC AND METHOD FOR MAKING THREE DIMENSIONAL INORGANIC FIBER FABRIC

PROBLEM TO BE SOLVED: To provide a three dimensional inorganic fiber fabric having a high strength as a skeletal material for fiber reinforced resin material by imparting a flexibility to inorganic fiber threads such as carbon fiber, glass fiber or carbon silicate fiber, etc., for prevention of breakage in weaving and preventing damage such as breaking of thread and wearing out by avoiding crash of a needle of sawing machine and the inorganic fibers in laminating the inorganic fiber fabric and sewing. SOLUTION: The three dimensional fiber fabric is produced in the following processes a process making converged thread 6 by bundling a plurality of carbon fibers 1 and covering the bundle with a water soluble or inflammable sheath fiber 5, a process weaving the threads 6 into a meshed fabric 8 having a space 7 through which a needle 4 penetrates, a process laminating a plurality of the fabrics 8 and stitching together the laminated fabric 8, 8 by inserting the needle 4 into the space 7 with a suture 11, and then a process opening the sheath fibers 5 used for covering by scouring or burning.
