This study investigates the effects of nanoclay particles on impact and flexural properties of glass fiber-reinforced unsaturated polyester (UP) composites. UP-reinforced nanocomposite containing 1.5 and 3 wt % nanoclay was used to manufacture laminated composite panels using glass fiber woven roving by hand lay-up method. X-ray diffraction and transmission electron microscopy analysis confirmed intercalation and exfoliation of the nanoclay in the UP resin. Flexural test results indicated better performance for the specimens containing 1.5 wt % nanoclay reinforcements. However, Izod impact test results showed a decrease with increase in nanoclay content. High-velocity impact tests were carried out on a gas gun in velocity range of 90-220 m/s using harden steel hemispherical tip projectile. Highest performance in ballistic limit and energy absorption were obtained for specimens containing 1.5 wt % nanoclay.
