Development and Mechanical Testing of Filament Wound FRP Composite Components

Abstract

Glass Fiber Reinforced Plastic composites are used for pipes, high pressure vessels, aircrafts, automobiles, sport goods and Glass Fiber Reinforced Plastic composites are used for pipes, high pressure vessels, aircrafts, automobiles, sport goods and structural applications due to their high corrosion resistance, high specific strength, low density, low coefficient of thermal expansion, durability, low maintenance and low cost. This paper presents the development and mechanical testing of filament wound Glass Fiber Reinforced Plastic composite hollow cylindrical components. In this present work, Glass Fiber Reinforced Plastic composite hollow cylindrical components were manufactured by helical filament winding process. ASTM: D2584 standard test method for ignition loss of cured reinforced resins was conducted on the specimen to determine the fiber to resin ratio. The tensile test was conducted as per ASTM: D638 standard. The three point flexural test was conducted as per ASTM: D790 standard. The hoop tensile strength test was conducted as per ASTM: D2290 standard. The external loading characteristics were determined by conducting the ASTM: D2412 standard test. The tensile strength and flexural strength in the axial direction are 50.76 MPa and 425.46 MPa respectively. The hoop tensile strength and the parallel-plate loading (Compression) stiffness are 156.33 MPa and 2750 N/mm respectively.
