Abstract:
A method of preparing a thin-walled, non-fragmenting composite warhead casing which comprises impregnating carbon fibers with effective amounts of at least one liquid epoxy resin at ambient temperatures and wrapping the impregnated carbon fibers over a mandrel and maintaining the impregnated carbon fibers on the mandrel at ambient temperatures until the epoxy resin jellifies and subsequently heating the resin impregnated carbon fibers at temperatures ranging from about 125.degree. to 175.degree. F. until the epoxy resin cures on the carbon fibers to form the casing; said liquid epoxy resin having a low viscosity at ambient temperatures, a T(g) glass transition temperature ranging from about 200.degree. F. to 250.degree. F. and containing an effective amount of a curing agent.
