Analysis of Lap Joints in Composite Materials

Objectives: To characterize the Lap joints prepared by the Glass fiber reinforced composite materials. Methods/Statistical Analysis: Composite plates were prepared with Glass fiber reinforced composite materials with Epoxy resin. Tensile specimens were prepared as per the ASTM standards for the tensile test using Water jet cutting. During manufacturing hand lay-up method was followed to simplify the work. Tensile test was carried out to characterize the materials. Findings: 3 types of specimens were analyzed and from the testing we found that the peak stress of 47.41 MPa and Young’s Modulus of 14.3 Gpa were obtained. Application: The hand lay-up method used in Aerospace Industries, Mechanical Joints.
