Fabrication and Experimental Evaluation of Mechanical Properties of E-Glass and Aramid Short Fiber Reinforced Composite Material

Composite materials play a very important role in the field of engineering. Composites materials are widely used in aeronautical, automotive, space, transport, marine, sports and military industries. In this present study hybrid composite of E-glass/Aramid fiber were prepared by Hand-layup technique. The glass fiber used is E-glass fiber of 6 mm length and aramid fiber used is also of 6mm in length. E-glass and aramid fibers acts as a reinforcement phase and epoxy resin (LY556) acts as a matrix phase. The composite samples were made in the form of plate/sheets. Specimens were cut from the fabricated laminate according to the ASTM standard for different experiments for tensile test, flexural text, and compression test. The tests were carried as per ASTM standard, D-3039 for tensile test, D-3410 for compression and D-790 for flexural test. Results of the mechanical properties of composites were obtained by tensile, bending and compression tests. From the results obtained from the tensile strength test it has been seen that, addition of aramid fibers improves the tensile strength of the specimen. The reason we know that the tensile strength of the aramid fibers is more compared to the epoxy polymer hence the strength has gone up with the addition of the aramid fibers. From the results obtained from the compression strength test it has been seen that, addition of aramid fibers improved the compression strength of the specimen. The reason we know that the strength of the aramid fibers is more compared to the epoxy polymer hence the strength has gone up with the addition of the aramid fibers. From the results obtained from the flexural test yields that, addition of aramid fibers reduces the flexibility of the composite. Addition of the glass fiber also affected in the same manner.
