| Summary: | This paper presents an experimental work on the influence of number of layers in the
overwrap hybrid composite columnars under repeated axial crush force. The columnar test specimens
were fabricated by hand lay–up process using commercial available of 0/90° ply oriented epoxy-glass
fiber mats. In determining the energy absorption capacity, three different columnar tubes were prepared
using one-layer, two-layers and three-layers in order to determine the utilize of such fibers in structural
automotive applications. Quasi-static crush test for these tubes was carried out using Instron machine
with axial loading. Results showed that the axial crush force and the numbers of layers influenced the
level of energy absorption before structures collapse. It is found that the initial peak crush force, mean
crush force, crush force efficiency and energy absorption properties of the collapsed hybrid composite
columnars were increased by adding of layers in the overwrap thickness. |
