This study presents the response of twill glass fiber-epoxy laminates enhanced with different nanomaterials (0.5 wt%) subjected to high-velocity ice impact. The mechanical properties and ice impact performance of specimens were evaluated on different nanomaterials. The effect of the amine-functionalized carbon nanotubes (AFCNTs) on the ice impact behaviour was studied. To investigate the effect of manufacturing method of nano-glass fiber-epoxy laminated plates, hand lay-up and vacuum infusion process (VIP) were employed, and ice impact resistance of the laminated plates was measured by high-velocity (138 m/s) ice impact tests. The VIP method resulted in inappropriate distribution of nanomaterial into epoxy resin, therefore hand lay-up method was selected for manufacturing of the laminated plates reinforced with nanomaterials. Moreover, 9.2 g cylindrical ice impactor with flat, hemispherical and conical tips was manufactured to investigate the effect of ice impactor nose shapes in the same level of energy (96.7 J). The failure modes and damage area were reported for all specimens. Scanning electron microscopy was utilized to describe morphology of nanomaterials on laminated plates. The results showed that the damage formation in specimens depends on the type of nanomaterial used. It was concluded that the multi-walled carbon nanotubes improved the ice impact response by restricting the damage area in laminated plates. A significant decrease in the absorbed energy capability of specimen with AFCNTs was observed under ice impact loading. The conical ice projectile provided a lower level of damage compared to the hemispherical and flat ice projectiles.
