Abstract(s)This work studies and compares the processability into final composite parts of three different pre-impregnated materials, produced by different wetting techniques. All studied pre-impregnated materials were based on a continuous glass fibers reinforced polypropylene matrix (GF/PP) system. One is a tape produced in a previous work by using the melting process (cross-head extrusion) and, from the other two produced by fiber/matrix intimate contact methods, one is a commercial available commingled fibers product and the other a towpreg produced by our own developed dry coating prototype line. Pultrusion and compression molding were the manufacturing methods selected to process all the pre-impregnated materials into final composite parts. The performance of the three studied GF/PP pre-impregnated materials was assessed by comparing final properties of the manufactured composite parts submitted to mechanical testing and microscopy analysis.
