Abstract

A filiform article comprises a fiber wrapped, fiber core impregnated with resin. Reinforcing fibers are organized into cores that contain at least one reinforcing fiber, but preferably contains a plurality of fibers. The core is surrounded by a sheath containing a wrapping fiber. The wrapping fiber is preferably wrapped around the core with tension. The core is impregnated with a flowable, hardenable resin preferably after the core is wrapped. The diameter of the filiform article is preferably no more than 1.5 mm. The filiforms may be prepegged according to known practices.
