Abstract
The invention involves recycling scrap material having a thermoplastic. The invention includes a method of forming a thermoplastic pre-preg sheet for use in a subsequent molding operation. The method includes shredding a first scrap material having a thermoplastic to form fluff. The fluff has at least about 20 percent weight of thermoplastic. The method further includes sufficiently compacting the fluff into a thermoplastic state sufficient for forming the thermoplastic pre-preg sheet.
