Among composite materials, Natural fiber reinforced polymer finds rapid development in industrial applications and many areas of research. In this paper, thermal properties of Sisal-Glass fiber reinforced epoxy composites are studied to assess the influence of different fiber orientation. Thermal properties of the composite are analyzed using Thermo Gravimetric Analysis (TGA) and Differential Thermal Analysis (DTA) to investigate the influence of change in fiber orientation.Copyright © 2015 by ASME

Many industrial applications and research people prefer thermoplastic polymeric matrices than thermosets due to the very low production time, very low processing cost and availability of thermoplastics. With an increase in demand for composite materials like Glass Fiber Reinforced (GFR) are widely used as reinforcement in thermoplastic polypropylene (PP) matrix to prepare composites. In this study, Glass Fiber Reinforced Polypropylene composites were developed and their mechanical properties were evaluated. In the present work, Glass fiber Reinforced Thermoplastic Polymer Composites is fabricated by Hot press Hydraulic compression molding Technique. The average Strength of thermoplastic polymer matrix with Glass Fiber (GFR/PP) reinforced composite is studied. Test is carried as per the ASTM standards. This study characterizes mechanical properties like Tensile, flexural and impact properties. Scanning electron microscopic (SEM) images of fractured specimen were used for qualitative evaluation of the interfacial properties of Glass Fiber Reinforcement Polypropylene composites.
