Abstract
AbstractIn the present study, a comparison has been made between the mechanical properties of polyester and epoxy matrices reinforced Sisal/S‐Glass, and also the effects of nano clay addition have been studied. For fabrication of composites, Glass/Sisal fibers are reinforced with Polyester and Epoxy with various wt% of nano clay. These composites are fabricated through the hand lay‐up technique. Various wt% of nano clay are 2, 4, 6 wt%, and the stacking sequence of fibers are GSSG (S‐Glass/Sisal/Sisal/S‐Glass). The variations of strengths among the polyester/epoxy are also studied and examined. In Epoxy/GSSG reinforced NC composites compared with 0–4 wt% tensile strength increased by 18%. Polyester/GSSG reinforced NC composites tensile strength increased by 16%, and in Epoxy/GSSG reinforced NC composites compared with 0–2 wt% flexural strength increased by 16%. Polyester/GSSG reinforced NC composites tensile strength increased by 24%. The microstructural analysis has been carried out on the fractured samples, which indicated brittle failure of the fiber and fiber pull‐outs. This conclusion confirms the proposed novel laminates fitness for possible usage in structural applications in the aerospace sector.
