Effect of Transcrystallization and Thermal Treatment on Interfacial Bond Strength of Glass Fiber/ Polypropylene Composites

摘要：

The strong orientation of the transcrystalline layer in glass-fiber/polypropylene composites has affected the mechanical properties of composite materials by altering interfacial structure and drawn much interest.Experimental studies on single fiber polypropylene (PP) matrix composites by the fragmentation tests had shown that transcrystallinity increased the efficiency of stress transfer at the fiber-matrix interface 1, thus increasing the interfacial shear strength. However, some researchers had shown that transcrystallinity could decrease the interracial shear strength by pull-out tests 2-3. Others also concluded that the presence of a transcrystalline interphase did not have any significant influence on the fiber-matrix adhesion by using a tensile testing machine 4.
