ABSTRACT:
A heat-resistant prepreg uses at a substrate a heat-resistant material made of heat-resistant organic fibers, inorganic fibers, etc. and as a matrix a heat-resistant mixture containing at least 10% by weight of a borosiloxane resin composition. This heat-resistant prepreg is obtained by impregnating the substrate at a temperature in the range of 200.degree. to 300.degree. C. to such an extent that at least 20% of the amount of phenyl groups bonded to silicon atoms in the aforementioned borosiloxane resin composition prior to the impregnating and drying steps will remain after the heat treatment.
