Tensile Tests of Glass Powder Reinforced Epoxy Composites: Pilot Study
Epoxy resin was filled with glass powder to optimize the strength and of the composite for structural applications by a research centre in the University of Southern Queensland (USQ). In order to reduce costs, the centre wishes to fill as much glass microspheres as possible subject to maintaining sufficient strength and fracture toughness of the composites in structural applications. This project varies the percentage by weight of the glass powder in the composites. After casting the composites to the moulds, they were cured at ambient conditions for 24 hours. They were then post-cured in a conventional oven and subjected to tensile tests. It was found that the best percentage of glass powder by weight that can be added to the epoxy resin to give an optimum yield and tensile strengths as well as Young modulus and cost was five percent. It was also found that the fractured surfaces examined under scanning electron microscope were correlated with the fracture toughness. The contribution of the study was that if tensile properties were the most important factors to be considered in the applications of the composites, glass powder is not a suitable filler. It is also hoped that the discussion and results in this work would not only contribute towards the development of glass powder reinforced epoxy composites with better material properties, but also useful for the investigations of tensile properties in other composites.
