The energy absorption behavior of hybrid composite laminates containing nano-fillers under ballistic impact

Abstract:

Hybrid composite laminates consisting of woven Kevlar fiber fabric, epoxy and AA 5086-H32 aluminum sheets were produced and the effects of addition of micro and nano-fillers to the fiber on ballistic response of the hybrid laminates were investigated. The micro and nano-fillers used in this study are powders of aluminum, gamma alumina, silicon carbide, colloidal silica and potato flour. They were introduced into the Kevlar fabrics by mixing with polyethylene glycol (PEG-400), followed by impregnation of the Kevlar fabric with the mixture and drying to eliminate the solvent. The energy absorption by the hybrid composite laminates containing the various nano-fillers under ballistic impact were determined and compared with laminate containing no nano-filler impregnation. The ballistic impact resistance of the produced hybrid composite laminates was tested according to NATO standards using a caliber 270 …
