Fabrication of Glass/Jute Hybrid Composite over Wrapped Aluminum Cylinders: An Advanced Material for Automotive Applications

Abstract

As a class of promising cost-effective lightweight structures, metal-composite hybrids have rapidly emerged in automotive industry largely attributable to their outstanding multifunctional and crashworthy characteristics. The aim of this study is to investigate the potentiality of metal-composite cylinders for crash energy absorption applications. In this context, the crashworthiness performance, and the deformation history of jute (J)/glass (G) reinforced epoxy hybrid composite over wrapped aluminum (Al) cylinders were experimentally studied under quasi-static axial loading. Crashworthiness characteristics of the proposed cylinders were evaluated by measuring the average and peak crushing loads ($${\mathrm{F}}_{\mathrm{avg}}$$ F avg , $${\mathrm{F}}_{\mathrm{ip}}$$ F ip ), specific energy absorption ($$\mathrm{SEA}$$ SEA ), total absorbed energy ($$\mathrm{U})$$ U ) , and crush force efficiency ($$\mathrm{CFE}$$ CFE ). The influence of the number of J-layers on the deformation profiles has also been defined. Result revealed that the highest ($${\mathrm{F}}_{\mathrm{ip}}$$ F ip ), ($${\mathrm{F}}_{\mathrm{avg}})$$ F avg ) , and ($$\mathrm{SEA}$$ SEA ) noted for Al-3G-2 J-3G with values of 85.45 kN, 53.14 kN, and 39.99 J/g, respectively. The maximum ($$\mathrm{U}$$ U ) was documented for Al-8G with a value of 3535.89 J. The highest $$(\mathrm{CFE})$$ ( CFE ) was recorded for Al-2G-4 J-2G followed by Al-3G-2 J-3G with a value of 0.65 and 0.62, respectively. Al-3G-2 J-3G cylinders exhibit excellent energy-absorbing capacity and could be applied as energy-absorbing crashworthiness structures in automotive applications.

Multi attribute decision making through COPRAS on tensile properties of hybrid fiber metal laminate sandwich structures for aerospace and automotive industries

“…Increasing the surface roughness helps to introduce a good bond between Al-sheets and fabrics. The same results were obtained by Megahed et al, 4 Abd El-baky et al, 23,60 and Alshahrani et al 66 .…”

“…Kemapoxy 150 RGL was chosen as a matrix. Kemapoxy 150 RGL has been successfully applied in the literature [53][54][55][56][57][58][59][60] because it is distinguished by a strong resilience to chemical and mechanical properties. Table 2 shows the physical and mechanical properties of Kemapoxy 150 RGL given by the supplier.…”

Carbon‐glass reinforced epoxy hybrid composites for crashworthy structural applications

“…[7][8][9][10][11] The term "crashworthiness" may be described as the material's capacity to protect its occupant from harm in crush incidents. [12][13][14][15][16][17] Several candidates of materials can be used for crashworthy devices. Because of their controllable deformation, metals like steel (St) and aluminum (Al) are commonly used.…”
