Physico-chemical properties of compression molded glass fiber reinforced polypropylene polymer composites

Abstract

This article reports the material properties of short random discontinuous oriented glass fiber reinforced polypropylene composite is studied. The composite was prepared using compression molding process. The mechanical, structural, and thermal properties were observed by using universal testing machine, FTIR, XRD and DSC. The FTIR confirms the interaction between polypropylene and glass fibers. Semicrystalline nature is confirmed by XRD. The influence of temperature on viscosity and relaxation times in a material were analyzed using WLF and VTF equations. Mechanical stability is evaluated using stress -strain plots.
