1. A method of producing a polymer matrix composite, comprising:

  • (1) mixing a first poly ether polyol having a first molecular weight and a second poly ether polyol having a second molecular weight higher than the first molecular weight with one or more catalysts, water, and optional surfactant;

    (2) optionally introducing reinforcing fibrous materials into the mixture;

    (3) introducing inorganic filler into the mixture;

    (4) introducing poly- or di-isocyanate into the mixture; and

    (5) allowing the exothermic reaction to proceed without forced cooling except to control runaway exotherm, thereby forming a polymer matrix composite.
