Abstract
A chopped roving thermoplastic composite sheet includes a web or mesh of chopped rovings and a thermoplastic resin that fully saturates the web or mesh of chopped rovings. The web or mesh of chopped rovings is not mechanically bonded and does not include a binder that bonds or adheres the chopped rovings together other than thermoplastic resin. As such, the thermoplastic resin and the web or mesh of chopped rovings are able to flow and conform to a mold or cavity when the chopped roving thermoplastic composite sheet is pressed within the mold or cavity and when the chopped roving thermoplastic composite sheet is heated to above the melting temperature of the thermoplastic resin.
