Mechanical Properties of Drilling Defect Induced Glass Fiber Epoxy Composites Developed By Resin Infusion Technique

Composite laminates such as Glass Fiber Reinforced Epoxy (GFRE), Carbon Fiber Reinforced Epoxy (CFRE) and other fiber metal composite laminates have been widely used in industries which include aerospace, aircraft structural components and oil and gas fields due to their superior mechanical properties. Drilling can be considered as an important machining operation for the assembling of laminates. By reason of hard-to-machine characteristics of the components, the drilling operation induced defects. This paper studies the mechanical properties that are affected from the induced defect. In this research, GFRE composite were used and fabricated using the vacuum assisted resin infusion method. The results of the drilled samples were tested for its tensile strength and structural analysis. This research is intended to help readers obtain a comprehensive view on mechanical properties of glass fiber reinforced epoxy.
