Composites have gained wide use in structural applications; however, they are sensitive to impact damage. The use of hybrid composites is an effective way to overcome this deficiency. The effects of various hybrid structures of interlayer and intralayer warp-knitted fabrics with carbon and glass fibers on the low-velocity impact behavior of composite laminates were studied. Drop-weight impact tests were conducted on two types of interlayer, sandwich and intralayer hybrid composite laminates, which were compared with homogenous composite laminates. During low-velocity impact tests, the time histories of impact forces and absorbed energy by laminate were recorded. The failure modes were analyzed using the micro-CT (computed tomography) and C-scan techniques. The results revealed that the hybrid structure played an important role in peak force and the absorbed energy, and that the hybrid interface had an influence on damage modes, whereas the intralayer hybrid composite laminate damage was affected by the impact location. The intralayer hybrid laminate with C:G = 1:1 exhibited better impact resistance compared to the other hybrid structures.

Low velocity impact tests were carried out on T300/QY8911 and CCF300/QY8911 composite laminates, which led to similar impacted damage characterized by dent depths on laminates. Compression/compression fatigue strength tests of the impacted laminates were further conducted. The comparison of the compression/compression fatigue performance between the two types of composite laminates with similar impacted damage shows the compression/compression fatigue behaviors of T300/QY8911 and CCF300/QY8911 are similar. It follows that the CCF300/QY8911 is an effectively alternative to the T300/QY8911 in damage tolerance behavior.
