Abstract
A polymer matrix composite comprises a matrix of a cured methylsilsesquioxane resin and a reinforcing material. The composite has low heat release rate, smoke yield, and carbon monoxide yield when burned. After burning, the composite has high char yield and retains much of its initial tensile strength. The method for making the composite comprises applying a silanol-functional methylsilsesquioxane resin comprising 70 to 90 mol % ((CH.sub.3)SiO.sub.3/2) units and 10 to 25 mol % (CH.sub.3 Si(OH)0.sub.2/2) units to a reinforcing material and curing the resin.
