摘要

This article involves the study of the enhancement of tensile characteristics of ABS-cross linked epoxy powder composite reinforced with carbon fiber and graphene nanoparticles. Fractured surfaces of specimens under tensile loading are studied to analyze the type of fracture. An effort is made to recycle the cross-linked epoxy micro particles with ABS polymer, and also an experimental study is done on the composite to optimize the cross-linked epoxy proportion to ensure successful recycling of thermosetting polymer. Carbon fiber and graphene nanoparticle reinforcements are used to further enhance the mechanical properties of ABS-epoxy composite. Specimens of the tensile test are fabricated with various proportions of carbon fiber and graphene nanoparticles using a micro compounder injection molding machine. A tensile test is carried out as per the ASTM D 638 standard, and the test results obtained are compared with the properties of neat ABS as well as the ABS-epoxy composite. The highest tensile strength of 49.5 MPa and maximum percentage elongation of 18 are obtained for the optimum proportion of 10% cross-linked epoxy powder, 10% carbon fiber and 2% graphene nanoparticle composition. Scanning electron microscopy images confirmed the reinforcement particles' proper dispersion and show the fracture behavior of the composite, which is in correlation with the tested properties.
