This thesis reports a study on the melt impregnation and weaving of glass/PP pre-preg tapes into sheet for use as the precursor for pressed thermoplastic composite products, and a comparison of the properties attainable with those achievable by other comparable routes. Melt impregnation has been used successfully to manufacture well-impregnanted tapes of polypropylene and glass fibres, with and without coupling agent. It appears that weaving could be an economically viable process for converting unidirectional tape into a press-formable pre-preg.
