Abstract Glass fiber reinforced plastic composites are widely used as structural materials. These two phase materials can be tailored to suit a large variety of applications. A better understanding of the properties of the fiber-matrix ‘interphase’ can enable more optimum design of composites. The interphase is a microscopic region around the fiber and hence nano-scale investigation using nano-indentation techniques is appropriate to determine mechanical property variations. In this study the atomic force microscope with the Hysitron indenter has been used to determine the variation of the elastic modulus across the interphase for different silane coated glass fiber reinforced polyester composites. A comparative study of the elastic modulus variation in the interphase is reported. The results are discussed in the light of the current limitations of the instrumentation and analysis.

Composite materials are widely used today in many sectors. Glass fiber reinforced plastic composite materials are one of those. Glass fiber reinforced plastic composite materials are preferred due to their high thermal and tensile strength. Although consist of glass fiber reinforced composite materials from multiple layers reduces the machinability of these materials, drilling is a common method of machining for these materials. However, when the drilling parameters are not carefully selected, the material integrity is deteriorated and the desired drilling quality cannot be obtained. In this study, the effect of drilling temperature and thrust force on the material integrity was investigated. The drill bit angle, spindle speed and feedrate parameters are used for the temperature and thrust force analysis.

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.
