Hybridization Effects of S-glass fiber on Charpy impact resistance of carbon/aramid fiber reinforced epoxy composite laminates

Abstract

The objective of the present research work is to investigate the Charpy impact behavior of intraply hybrid carbon/aramid fabric layers with S-glass fabric layers composite laminates for asymmetric and symmetric arrangements. The hybridization effects on Charpy impact characteristics for carbon/aramid with S-glass hybrid composite laminates were compared with those of carbon/aramid/epoxy composite laminates and S-glass/epoxy composite laminates. Deformation degree, impact energy and impact strength were strongly affected by the position and number of carbon/aramid layers in addition to the impact side direction due to variation of impact properties between carbon/aramid fibers and S-glass fibers. Using S-glass layers instead of carbon/aramid layers exhibited decreasing in the deformation level particularly for carbon/aramid side impact in addition to improve the impact strength of the hybrid composite.
