The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely understood threat. Repeated ice impact events, such as the ones during a hailstorm, can cause significant damage. This work focuses on repeated ice impact experiments and damage in composite and nanocomposite materials. X-ray diffraction analysis confirmed the exfoliation and intercalation of the nanoclay in the studied epoxy resin system. The result shows that plates with a fiber orientation of [45°/45°]s in the composite produce the minimum delamination and that a small amount of nanoclay is enough to improve the mechanical properties of the nanoclay-polymer nanocomposites. %U https://www.ijnnonline.net/article_3876_e130b46f940cdabc31ae92a6d964f195.pdf
