Impact response of glass/epoxy laminate interleaved with nanofibrous mats (original) (raw)

Plain and nanofiber-interleaved glass/epoxy laminates clamped according to ASTM D7136 tested under impact loading to assess the improvement in impact resistance of composite laminates that have been interleaved by electrospun polyvinylidene fluoride (PVDF) nanofibers with two different thicknesses. Composite specimens with stacking sequence [0/90/0/90]S were impacted at impact energy of 5J. Variation of the impact characteristics such as maximum contact load, maximum deflection, maximum contact time, absorbed energy are depicted in the figures. The results showed that PVDF nanofibers are not a good choice for toughening epoxy and improving impact damage resistance of GFRP.
