Title: Production of Powder-Coated Towpregs and Composites
Published In: Journal of Thermoplastic Composite Materials, May 2003; vol. 16, 3: pp. 231 - 248
Description: Abstract: An efficient 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 processing parameters on manufactured glass fiber reinforced polypropylene (GF/PP) towpregs are detailed in this paper. Composites were produced from characterized (GF/PP) towpregs using hot plate compression molding. The mechanical properties determined on the composites are compared with theoretical values predicted by the Classical Lamination Theory (CLT) using the experimentally determined raw material contents and tensile properties.
