A manufacturing method of combining wires and fibers to fabricate fiber reinforced composites is disclosed. The fibers are drum wound on an adhesive-coated substrate followed by coating with a barrier layer to preserve the fiber spacing. A layer of the adhesive material is then applied to the fiber wrap and wire is wound therearound. A series of increasingly viscous tacky materials can then be applied to the wire wraps so that all gaps between the wires are filled. The inventive method can be used to form standard wire/fiber preforms, variable spacing wire/fiber preforms, ring preforms and wire only preforms which can be processed into fiber reinforced composite materials.
