A polymer matrix composite is disclosed herein which comprises a matrix of a cured methylsilsesquioxane resin and a reinforcing material. The claimed composite has low heat release rate, smoke yield and carbon monoxide generation when burned. After burning, our composite has high char yield and retains much of its initial tensile strength. The method for making said composite comprises applying a silanol-functional methylsilsesquioxane resin comprising 70 to 90 mole % ((CH3)SiO3/2) units and 10 to 25 mole % (CH3Si(OH)O2/2) units to a reinforcing material and thereafter curing said resin.
