Low-velocity impact (LVI) and bump tests were performed on CFR-Epoxy composite laminates which plies were interleaved with electrospun nylon nanofibers. Bump tests are performed before and after the impact event. Nanosheets are placed in between plies interfaces during the hand lay-up process for specimen anufacturing. Two different configurations of the nanomodified laminate are produced. In the present paper the following three studies were developed: (i) the investigation about the vibration behavior of nano-interleaved composite laminates, (ii) the study the low velocity impact behavior of the nano-interleaved laminates, (iii) the investigation about post impact vibration behavior of the nano-interleaved laminates. All experimental tests were done by comparing virgin and nano-interleaved composite laminates. From the experiments a significant effect of nano-interleaves on the global behavior of laminates was found. Nanofibers are able to increase the absorbing energy capabilities of laminates and strengthen them after the LVI tests.

Abstract
Low-velocity impact (LVI) and bump tests were performed on CFR-Epoxy composite laminates which plies were interleaved with electrospun nylon nanofibers. Bump tests are performed before and after the impact event. Nanosheets are placed in between plies interfaces during the hand lay-up process for specimen anufacturing. Two different configurations of the nanomodified laminate are produced. In the present paper the following three studies were developed: (i) the investigation about the vibration behavior of nano-interleaved composite laminates, (ii) the study the low velocity impact behavior of the nano-interleaved laminates, (iii) the investigation about post impact vibration behavior of the nano-interleaved laminates. All experimental tests were done by comparing virgin and nano-interleaved composite laminates. From the experiments a significant effect of nano-interleaves on the global behavior of laminates was found. Nanofibers are able to increase the absorbing energy capabilities of laminates and strengthen them after the LVI tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
