PP/PA6 INSITU COMPOSITE I.MORPHOLOGY AND MECHANICAL PROPERTIES

PP and PA6 were extruded with a single screw extruder. PA6 could form microfibrils in PP matrix. When the blends were compression molded at the temperature between the melting temperature of PP and that of PA6, these fibrils could be maintained in the matrix. The existence of PA6 microfibrils improved the impact strength but the tensile strength of the composites decreased.
