Micro-structural, thermal, and mechanical properties of injection-molded glass fiber/nanoclay/polypropylene composites

Hybrid composites of PP/NC/GF were prepared by extrusion and injection molding. Molded specimens were analyzed by XRD, SEM, and TEM, together with characterization of thermal and mechanical properties. XRD results revealed that the interaction between NC particles and the PP matrix results in interc...
