Abstract
The present paper experimentally explores the influence of the fiber hybridization and layering sequence on crashworthiness behavior and deformation history of polymer/metal thin-walled pipes. Jute (J)/glass (G) reinforced epoxy over wrapped aluminum (Al) pipes were prepared via hand wet wrapping then subjected to axial quasi-static compressive loads. The load versus displacement plots and crashing indicators, i.e. peak crushing load ({mathrm{F}}_{mathrm{ip}}), mean crushing load ({mathrm{F}}_{mathrm{m}}), total energy absorption (mathrm{U}), specific energy absorption left(mathrm{SEA}right), and crush force efficiency left(mathrm{CFE}right) were determined. Experimental results revealed that the maximum left(mathrm{SEA}right) was recorded for Al/2J/4G/2J pipe with a value of about 42.92 kJ/g, with an enhancement of 20.56% in left(mathrm{SEA}right) compared with pure Al-pipes. Al/2J/4G/2J specimens display the maximum (mathrm{U}), left(mathrm{SEA}right), and left(mathrm{CFE}right) and could be employed as energy absorbing members in automobiles.
