New micro-structure designs of a polypropylene (PP) composite with improved impact property

In this paper, Hollow Glass Microspheres (HGMs) and Flexible Butadiene Nitrile Rubber Powders (BNRPs) were employed to jointly improve the impact property of polypropylene (PP). BNRPs and HGMs distributed in the PP matrix exhibited different modifying effects. Under the shocking force, large elastic...

Description
Summary:In this paper, Hollow Glass Microspheres (HGMs) and Flexible Butadiene Nitrile Rubber Powders (BNRPs) were employed to jointly improve the impact property of polypropylene (PP). BNRPs and HGMs distributed in the PP matrix exhibited different modifying effects. Under the shocking force, large elastic deformation and shear yielding of flexible BNRPs occurred and the HGMs, which had spherical shape with smooth surface and were embedded in the PP matrix in advance, could arrest the crack propagation just as “Stop-Drilled Holes” (“SDHs”). •New micro-structure designs of a PP composite with improved impact property were reported.•“Stop-Drilled Holes” (“SDHs”) and flexible rubber powders were employed to jointly improve the impact property of PP.•BNRPs and HGMs in the PP matrix exhibited different modifying effects.•A PP composite with improved impact property was developed.
