Abstract
The effect of strain rate on the mechanical properties of glass fiber reinforced polyester with and without Zinc Oxide (ZnO) nano-filler was studied. Awoven roving glass fiber reinforced polyester resin composite was fabricated by hand lay-up method, andtested under four different strain rates 0.01, 0.1, 1 and 6 s-1 with four different ZnO percentages 0, 1, 2 and 3 wt.%. In addition, the fractured samples were examined using Scanning Electron Microscope (SEM). The results indicate an increase in the strength with the increasing of strain rate and adding filler content up to 3 wt.%. It also shows an improvement on the fiber/matrix interfacial bonding at the highest strain rate and with adding ZnO nano-filler with 3 wt.%.
