  • System for producing a fully impregnated thermoplastic prepreg
    Patent number: 10857744
    Abstract: A thermoplastic prepreg includes a web or mesh of fibers in which the web or mesh of fibers includes chopped fibers. The thermoplastic prepreg also includes a thermoplastic material that fully impregnates the web or mesh of fibers so that the thermoplastic prepreg has a void content of less than 5%. The thermoplastic material is polymers that are formed by in-situ polymerization of monomers or oligomers in which greater than 90% of the monomers or oligomers react to form the thermoplastic material. The thermoplastic prepreg includes between 5 and 95 weight percent of the thermoplastic material and the chopped fibers that form the web or mesh of fibers are un-bonded.
