Textile Insert Molding as Novel Impact Resistant Enhancement technique for PP foams

摘要

In this study, polypropylene knit/foamed polypropylene composites were fabricated by using the textile injection molding technique. Foamed materials can reduce the quantity of the consumed material by introducing air through the usage of foaming agents. The textile was knitted from polypropylene fibers and matrix was foamed polypropylene. Since the textile and matrix are of similar materials, good interfacial properties can be achieved. In this paper plate bending and drop-weight impact properties of specimens with and without textile inserts specimens were examined. Plate bending and drop-weight impact properties of PP knit/foamed PP specimens were superior to those without textile inserts.
