  Abstract

This paper investigated the collapse behavior of aluminum cylindrical energy absorbers, fully or sectionally hybridized with glass fibers and epoxy resin. The fully hybrid aluminum cylinders were wrapped entirely with rib fibers. The cylindrical tubes in sectionally hybrid counterparts were wrapped with ribs containing glass fibers in two, three, and six sections and were tested once from the bare aluminum direction and once from the hybridized side. The tests were performed under low-velocity impact loading at a speed of 7 m/s and a mass of 80 kg. The results show that the highest energy absorption occurs in fully hybrid specimens. However, the amount of glass fibers used in sectionally hybrid samples is half that of a fully hybrid counterpart. Comparatively, therefore, the amount of specific absorption energy rates in cylinders with two composite ribs are 16 percent and 35 percent higher than that of the pure aluminum mode, depending on the number of composite layers used in the hybrid samples. Besides, in the samples that are hit from the bare aluminum side, the maximum crushing force value is smaller than those of the samples tested from the hybrid direction. Moreover, the outcomes of the samples modeled in the ABAQUS finite element software are compared with those of the experimental mode.
