Abstract:
     The preparation method of SiC fibre reinforced LMCAS composite material belongs to the field of ceramic-based composite material, and is characterized by that said invention uses industrial waste material LCAS as mother glass, blends MgO to regulate its expansion coefficient to make it match with reinforcing agent SiC fibre. The blending amount of MgO is 0-16 wt%, its relative thermal expansion coefficient variation is (16-39)X10 to the minus seventh power/deg.C, and the blending amount of SiC fibre is 20-50 Vol%, and when the MgO Blending amount is 5%, the optimum fibre blending amount is 35 Vol%, and its room temp. strength is up to 580 MPa, Kic=16MPa.
