  • Low density resin systems for improved filament-wound composites useful as rocket motor cases
    Patent number: 4421806
    Abstract: Filament-wound composite bodies are disclosed. These bodies contain filament-wound fibers and resin. The resin, when cured, has a density of less than 1.05 g/cc and exhibits a water pick up of less than 1% by weight. When uncured, the resin contains an aromatic vinyl hydrocarbon monomer and as its major component poly(1,2-butadiene), carboxy-terminated poly(1,2-butadiene) or mixtures thereof and has a viscosity of less than 2000 cps at 45.degree. C. These filament-wound bodies advantageously are embodied as rocket motor cases.
