Bending properties of compression molded three‐layer long fiber polypropylene composites

摘要: The results of studies on bending properties three-layer long fiber polypropylene composites are presented. Thirteen samples with glass fibers various lengths (i.e., 13, 25, 50 mm and continuous length) in the laminates were prepared by stamping. Bending shorter exhibited a large scatter. On substitution middle layer scatter was reduced. These have been explained basis flow models X-ray shadowgraphs, which showed that both slippage orientation during stamping major phenomena responsible for
