Morphology, Dynamic Mechanical and Mechanical Properties of Long Glass Fiber Reinforced Polypropylene and Polyvinyl Chloride Composites

Abstract:

The influence of long glass fiber (LGF) content on properties of PVC/PP composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that long glass fiber could effectively improve the mechanical properties and storage modulus of PVC/PP. The DMA reveals good miscibility between PVC and PP. Based on SEM, good interfacial adhesion between matrix and long glass fiber in PVC/PP/LGF composites was observed. All results in this paper were consistent, and showed long glass fiber could effective influence the properties of PVC/PP, which were proved by the mechanical properties of the composites.
