Impact behavior of nano-clay and nano-sio15 filled epoxy matrix based fiber reinforced composite laminates

In this study, the impact behavior of nanoclay and nanosilica filled epoxy matrix based glass fiber reinforced composite laminates ([G12] and [G10]) and aramid/glass hybrid fiber reinforced composite laminates were investigated by Charpy impact test. The composite laminates were fabricated by hand lay-up process. The Charpy impact test of fabricated composite laminates was conducted following ISO 179/92 standard by Köger 3/70 Charpy impact test machine. The results showed an increase in absorbing impact energy of the edgewise specimens of glass fiber reinforced composites were 19.44 % for 2 wt.% nanoclay addition and 38.02 % for 1.5 wt.% nanosilica addition. The increase in absorbed impact energy for flatwise test specimens of [G12] and [G10] was 11.38 % and 32.83 % for 2 wt.% nanoclay and 1.5 wt.% nanosilica, respectively. It was also shown that the highest impact energy absorption on hybrid fiber reinforced composites was obtained for both flatwise and edgewise test of [K1G4]S stacking configuration with 1 wt.% nanoclay additive.
