Polyisocyanate-based reaction systems, a pultrusion process employing those systems to produce reinforced matrix composites, and to composites produced thereby. The polyisocyanate-based systems are mixing activated reaction systems that include a polyol composition, a catalyst composition which comprises a combination of at least two different metals in effective amounts, an optional chain extender or crosslinker, and a polyisocyanate. The polyisocyanate-based systems facilitate the practical use of higher line speeds in the manufacture of fiber reinforced thermoset composites via reactive pultrusion. |
