Abstract

Abstract A new composition of matter comprises the product of the amassment of two or more arrays of glass roving or other suitable filaments, each of which array has been coated or impregnated with one of two complementary resin systems, preferably thermosetting polyester resin systems. Each such complementary resin system comprises substantially the same or functionally similar resin and each further comprises a curing agent, for example, in the case of polyester resin an organic peroxide, which curing agent differs from the curing agent in the other resin system. The resin system of each array further comprises suitable accelerator which is substantially ineffective to promote the curing agent of the resin system in which it is incorporated, but which does effectively promote the curing agent of the other, complementary resin system. Upon amassment of the separate arrays the two accelerators act synergisticly in the combined resin system. Thus, the resulting novel composition of matter provides an extremely rapid cure resin system, wherein curing agent is dispersed substantially uniformly throughout the resin to be cured. The invention is applicable to filament winding techniques and the like to provide extremely rapid curing even at room temperatures and to provide products having improved physical properties. Related aspects of the invention provide novel methods of preparing and novel methods of using the novel composition of matter.
