Low velocity impact analysis of carbon/glass/epoxy hybrid composite pipes

Composite pipes are widely used in automotive and transportation of liquid in various industries. Impact analysis of composites gives the knowledge to understand failure and damage resistance of the material during low velocity impact like tool drops and designing new component. In this work carbon and glass fibers are used to produce hybrid composite pipes. The effect of impact on hybrid composite pipes was carried out by finite element analysis with varying orientations and for varying thicknesses, fixing the internal diameter. The experimental validation is done for one of the orientation the results are compared with the finite element analysis results. The experimental and analysis results closely match each other. It was found that the impact resistance decreases with increase in the helix angle of orientation such as 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degrees respectively. The failure of the specimen determined by experimental method for (CG90/CG60)3 the orientation, it takes a peak force of 4358 N and 6935 N for 4 mm and 5.3 mm thickness respectively. The thicknesses 4 mm and 5.3 mm of the specimen increases the stiffness of the specimen, which further increases the impact resistance and reduces the deformation of the specimen.
