Abstract: Na eficiente and cost-effective dry coating process was developed to deposit polymer powders on continuous fibers and produce thermoplastic matrix towpregs to be processed into composites. The technological solutions used in the coating line construction and the influence of the precessing parameters on manufactured glass fibre reinforced polypropylene (GF/PP) towpregs are detailed in this paper.Composites were produced from characterized GF/PP towpregs using hot plate compression moulding. The mechanical properties determined on the composites are compared with theoretical values predicted by the Classical Laminate Theory using the experimentally determined raw material contentes and tensile properties.
