THERMOPLASTIC PREPREG
First Claim
1. A thermoplastic prepreg comprising:
- a fabric, mat, web, or mesh of fibers; and
a thermoplastic material that fully impregnates the fabric, mat, web, or mesh of fibers such that the thermoplastic prepreg has a void content of less than 5 percent by volume, the thermoplastic material comprising thermoplastic polymers that are formed by in situ polymerization of monomers or oligomers in which greater than 90 percent of the monomers or oligomers polymerize to form the thermoplastic polymer;
wherein;
the thermoplastic prepreg includes between 15 and 85 weight percent of the thermoplastic material; and
the thermoplastic prepreg includes a residual monomer or oligomer content consisting of monomers or oligomers that are not polymerized during formation of the thermoplastic polymer.

Abstract
A thermoplastic prepreg includes a fabric, mat, web, or mesh of fibers and a thermoplastic material that fully impregnates the fibers such that the thermoplastic prepreg has a void content of less than 5 percent. The thermoplastic material includes or consists of polymers that are formed by polymerization of monomers or oligomers in which greater than 90 percent of the monomers or oligomers polymerize to form the thermoplastic material and in which less than 100 percent of the monomers or oligomers polymerize to form the thermoplastic material. The thermoplastic prepreg includes residual monomers or oligomers since less than 100 percent of the monomers or oligomers polymerize and the thermoplastic prepreg includes between 15 and 85 weight percent of the thermoplastic material.
