Lightweight cost-effective hybrid materials for energy absorption applications

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 ($${\mathrm{F}}_{\mathrm{ip}}$$ F ip ), mean crushing load ($${\mathrm{F}}_{\mathrm{m}}$$ F m ), total energy absorption ($$\mathrm{U})$$ U ) , specific energy absorption $$\left(\mathrm{SEA}\right)$$ SEA , and crush force efficiency $$\left(\mathrm{CFE}\right)$$ CFE were determined. Experimental results revealed that the maximum $$\left(\mathrm{SEA}\right)$$ SEA was recorded for Al/2J/4G/2J pipe with a value of about 42.92 kJ/g, with an enhancement of 20.56% in $$\left(\mathrm{SEA}\right)$$ SEA compared with pure Al-pipes. Al/2J/4G/2J specimens display the maximum ($$\mathrm{U})$$ U ) , $$\left(\mathrm{SEA}\right)$$ SEA , and $$\left(\mathrm{CFE}\right)$$ CFE and could be employed as energy absorbing members in automobiles.

Carbon‐glass reinforced epoxy hybrid composites for crashworthy structural applications

“…[22] It has been effectively used by many authors in the literature. [22,24,25,[35][36][37] The mechanical characteristics of the reinforcements and matrix employed in this study are shown in Table 1.…”

“…Based on numerous studies, a crosshead speed of 10 mm/min was chosen for uniaxial quasi-static crush testing. [37,[39][40][41] Test specimens were set up between two flat steel plates that were parallel to each other before the test start. An autonomous data collection system was used to directly record loaddisplacement data.…”

Multi-response optimization of crashworthy performance of perforated thin walled tubes

“…51,52 Others performed the tests at V = 5 mm/min 53–55 . However, Ma and Yan 56 and Abd El-baky et al 57,58 selected V = 10 mm/min in their scholarships. In this study, the researchers tried to understand how crosshead speed affected the crushing attitude of the thin-walled, induced-hole (GFRP) tubes.…”

Jute-basalt reinforced epoxy hybrid composites for lightweight structural automotive applications

“…1–7 Because of these advantages, natural fibers are a viable option for completely or partially replacing synthetic fibers in various applications. 8–13 Despite their attraction, they have some difficulties when compared to synthetic fibers, including high variability, poor moisture resistance, weaker mechanical qualities, and lower impact resistance. 14,15…”

“…[1][2][3][4][5][6][7] Because of these advantages, natural fibers are a viable option for completely or partially replacing synthetic fibers in various applications. [8][9][10][11][12][13] Despite their attraction, they have some difficulties when compared to synthetic fibers, including high variability, poor moisture resistance, weaker mechanical qualities, and lower impact resistance. 14,15 Jute (J) is one of the most promising natural fibers because of its low cost, light weight, moderate mechanical properties, low thermal conductivity, moderate moisture regain, and vast production.…”
