Abstract
Lightweight filament wound composites are provided which comprise fibers in a cured matrix resin. The resin, in its uncured state, comprises an aromatic vinyl hydrocarbon monomer and a chain-extended carboxy-terminated poly(1,2-butadiene) made by reacting a carboxy-terminated poly(1,2-butadiene) and a difunctional compound in an equivalents ratio of difunctional compound/carboxyl of about 0.5/1.
Claims20
A cured, filament wound composite comprising fibers in a matrix resin, said resin comprising whe uncured an aromatic vinyl hydrocarbon monomer and a chain-extended carboxy-terminated poly (1,2-butadiene) made by reacting a carboxy-terminated poly(1,2-butadiene) with a difunctional compound capable of reacting with carboxyl groups in an equivalents ratio of difunctional compound/carboxyl of 0.5/1.
An uncured, resin-fiber combination in the form of a preimpregnated roving or tape wherein the fibers are impregnated with an uncured resin matrix comprising an aromatic vinyl hydrocarbon monomer and a chain-extended carboxy-terminated poly (1,2-butadiene) made by reacting a carboxy-terminated poly (1,2-butadiene) with a difunctional compound capable of reacting with carboxyl groups in an equivalents ratio of difunctional compound/carboxyl of about 0.5/1.
