The objective of this investigation is to comprise the influence of reinforcement agent in a composite material. In this case, the composites were fabricated by a hand lay-up technique. Three types of test specimens were prepared, with the main difference being the reinforcement material in the matrix−Sample 1: epoxy resin only, Sample 2: epoxy with MGFs, and Sample 3: epoxy with GO-coated MGFs.
All specimens were assessed with the aid of scanning electron microscopy and energy dispersive spectroscopy analysis to evaluate the coating and elements present in the samples. Mechanical properties were obtained in the American Society of Testing Materials (ASTM) standard tensile and flexural tests. Our results show that the addition of 0.4 wt.% GO as a coating to epoxy with MGFs improves the tensile strength with 8.64% concerning the strength of epoxy resin with MGFs and a unidirectional stitched fiberglass reinforcement. %8 2020-08-14
