Mechanical Characterization of Silica Sand and Aluminium Trihydrate Based Epoxy Hybrid Composite Using Cabosil/Glass Bead and Zinc Stearate Powder as Secondary Reinforcement
摘要
The hybrid filler composites are superior in terms of strength and durability, which makes them suitable for aerospace, automotive and energy industries. The present research is aimed at investigating the mechanical characteristics of different micro filler reinforcements such as; silica sand, aluminium trihydrate (ATH) in the varied ratio of 10, 20, 30, and 40% by weight fraction of epoxy and fixed ratio of glass beads, Cabosil, and Zinc stearate by 0.32,1.33 and 1.07 wt.% respectively as secondary reinforcements. Composites were characterized viz., tensile, flexural, and impact testing according to ASTM-standards. The results indicate that, sample S9 (30 wt.% ATH) had the peak impact strength of 0.676 J/cm2 and maximum bending strength was found to be 267 MPa for hybrid sample S10 (30 wt.% of Silica sand and ATH). Tensile test results indicate that sample S13 (i.e. 40wt.% of Silica sand and ATH) reports enhanced strength as compare to Pure Silica sand and ATH composite. Obtained results indicate that mechanical strength of the composite with optimized reinforcement content exhibit better performance, which are best fit candidates to recommend them in domestic as well as industrial applications.
