A fiber/resin composite whose resin phase is formed by at least initial actinic radiation curing of a resin composition comprising an actinic radiation curable first resin component and a second resin component which is non-cured under curing conditions effective for the first resin component. The actinic radiation exposure of the fiber/resin composition effects curing of the first resin component to immobilize the composite and impart structural integrity thereto, whereby the composite may be handled, packaged, or further processed. Filament wound, braided, and pultruded articles are described, together with associated methods for forming such articles by filament winding, braiding and pultrusion. As a specific embodiment, a solid fuel rocket motor is disclosed comprising a solid fuel body in a filament wound fiber-resin composite casing formed by filament winding of the solid fuel body with resin-impregnated filament or rovings thereof.
A solid fuel rocket motor precursor article, comprising a solid fuel body in a filament-wound fiber-resin composite casing, said casing being formed by filament winding on said solid fuel body of a continuous filament impregnated with a resin composition comprising an actinic radiation-curable first resin component and an ambient temperature curable second resin component, wherein the actinic radiation-curable component is present in an immobilizingly effective amount for said composition prior to ambient temperature curing of the second resin component, and wherein said resin composition has been subjected to actinic radiation curingly effective for the first resin component and is ambient temperature curable in respect of the second resin component.
A solid fuel rocket motor precursor article, comprising a substantially cylindrical solid fuel rocket body in a filament-wound fiber-resin composite casing formed thereon, said fiber-resin composite including continuous filament in a resin matrix comprising an actinic radiation-cured first resin component and an ambient temperature-curable second resin component.
