Abstract

The present invention is generally directed to prepreg composites, typically in the form of unidirectional tapes, which contain at least one reinforcing fiber and a thermoplastic polyester matrix. The prepreg composites can be thermally bonded to a wood-containing material in order to improve the structural performance of the material without requiring adhesives. The prepreg composite of the present invention can be applied to a wide range of wood substrates, including various hardwoods, softwoods, and engineered wood composites.
