摘要：The conventional materials fail to meet the requirements of high technology applications like spaceapplications. In order to meet the requirements like high temperature and wear resistances new materials are beingsearched. The composite materials are the best alternative for those applications.The applications of composite materials have recently increased because of high strength/stiffness for lower weight,superior fatigue characteristics, facility to change fiber orientations, etc. At the same time, these materials pose newproblems such as inter ply cracking, inter laminar de-lamination and fiber cracking. Composite materials failure can bereduced by increasing fracture toughness.Our aim is to evaluate the fracture toughness of glass fiber/epoxy composites. Composites were prepared with glassfiber reinforced with epoxy based polymer. The fracture toughness of the specimen was employed to conduct mode-Ifracture test using special loading fixtures as per ASTM standards of DCB5528 specimen.
