Column buckling and Charpy impact behavior of locally nested intraply hybrid composites were investigated. Pure glass fiber/epoxy, pure carbon fiber/epoxy and three different types of glass fiber/carbon fiber/epoxy hybrid specimens were fabricated by vacuum-assisted resin transfer molding (VARTM) method. The buckling tests were performed with universal testing machine and load versus displacement values were recorded. For the impact tests, instrumented Charpy impact test machine was used and absorbed energy values were calculated using load versus time graphs. Hybrid specimens showed critical buckling load values close to pure glass specimen while pure carbon specimen has the highest critical load up to 1288 N. Critical load values for hybrid specimens ranged between the pure specimens, while impact results were more complicated. Impact tests showed that pure glass specimen has the highest absorbed energy values while particular type of hybrid specimen absorbed the least. When carbon fibers located at external surfaces of the specimen, buckling and impact response of the specimens are improved by 2.7 and 57%, respectively. Increasing number of contact surfaces between fiber types also improved the buckling loads and absorbed energy amounts. Damaged impact specimens further investigated with SEM and damage propagations were analyzed.
