PURPOSE:To produce a fiber-reinforced inorg. body capable of preventing the breakage of the reinforcing short fiber, producing a sufficient reinforcing effect and easily forming a large-sized article of complicated shape having a low sp.gr. CONSTITUTION:An emulsion contg. 100 pts.wt. of cement, 0.4-40 pts.wt. of the carbon short fibers having 1-20mm average length, 20-500 pts.wt. of water and 1-150 pts.wt. of the styrene contg. 0.5-5wt.% of a polymerization initiator and 3-50wt.% of an emulsifier is firstly prepared. The emulsion is injection-molded, and the obtained formed body is cured and aged. |
