ABSTRACT:
A structural reinforcement substrate with a conformable batt of relatively long staple oriented structural fibers disposed between at least two layers of randomly oriented short staple fibers and method of production thereof provides a strong, cohesive product which can readily be handled upon subsequent molding yet is readily conformable. Preferably, long oriented structural fibers are used in a plurality of planar elements. The jet orifices are widely spaced to minimize hydro-entanglement such that the original planar relationships of the fibers are substantially maintained.
