Abstract
A cured composite material formed in accordance with the method of the present invention. The method initially providing for providing a peel-ply sheet which defines opposed planar faces. A multitude of elongate bond fibers are embedded into the peel-ply sheet in a manner wherein a majority of the bond fibers do not extend in co-planar relation to the planar faces of the peel-ply sheet. A resin composite material is provided. The peel-ply sheet is applied to the resin composite material such that the bond fibers are partially embedded therein. The resin composite material is cured. The peel-ply sheet is removed from the cured resin composite material such that the bond fibers remain implanted therein.
Claims6
A cured composite material formed in accordance with the method comprising the steps of:
- a) providing a peel-ply sheet formed of intermeshed transfer fibers and bond fibers woven together;
- b) providing a resin composite material;
- c) applying the peel-ply sheet to the resin composite material such that the bond fibers are partially embedded therein;
- d) removing the peel-ply sheet from the cured resin composite material such that the transfer fibers are separated from the resin composite material and the bond fibers are fractured so as to form bond fiber fragments which are partially embedded in the cured resin material and partially protruding from the cured resin composite material.
