“…Besides, foam-filled thin-walled tubes were introduced to enhanced the energy absorption while maintaining the mass of the vehicle. This is because the foam helps to support the energy absorption capability of the structure [22]. It was supported by a study conducted by Hussien et al that found the specific energy absorption of foam-filled structure was higher compared to hollow one [1].…”

Crash box are the structural part designed to absorb energy during crash and minimize the injury to passengers. Various design of energy absorbers has been introduced to unleash design with the best crashworthiness behavior. Foam-filled structures are one of the promising designs. In this study, foam-filled structure was investigated to increase the energy absorption capability and reduce the initial peak force simultaneously. Since most foam-filled structures tend to absorb more energy with high peak force, optimization of the energy absorbers is significant in obtaining the optimum design. Response surface methodology (RSM) has been dominant technique in crashworthiness optimization mainly because of it provides efficient and accurate solution. This paper focused on the optimization foam-filled columns with respect to thickness of the tube and length of foam to enhance energy absorptions and reduce initial peak force. The optimization results suggested by Design Expert software for impact test is 515.9 J for EA and 134.94kN for IPF value with the column thickness of 2.0mm and foam length of 185mm. For quasi-static test, the optimum solution value for EA and IPF are 864.5J and 88.33kN respectively with column thickness of 1.87mm and foam length of 200mm.

“…Polyurethane foam are one of the low density or light weight material that often used for reduce the weight of structure which investigating by Niknejad [8]. The influence of foam density of polyurethane foam-filled steel tubes under quasi-static loading was also study by Onsalung et al [9,10]. The earliest investigations on the crushing behavior of thin-walled metallic tube filled with polyurethane foam was conducted by Guillow et al [11], who study the average crushing loads of polyurethane foam-filled thin-walled aluminium tubes under quasi-static and dynamic condition.…”

In this paper, the experimental investigation of polyurethane (PU) foam-filled into circular aluminum tubes subjected to axial crushing was presented. The purpose of this study is to improve the energy absorption of aluminium tube under axial quasi-static load. The aluminium tube was made from the AA6063-T5 aluminium alloy tubes. Each tube was filled with polyurethane foam. The density of foam was varied from 100, 150 and 200 kg/mP3P including with empty tube. The range of diameter/thickness (D/t) ratio of tube was varied from 15-55. The specimen were tested by quasi-static axial load with crush speed of 50 mm/min using the 2,000 kN universal testing machine. The load-displacement curves while testing were recorded for calculation. The mode of collapse of each specimen was analyzed concerning on foam density and the influence of D/t ratio. The results revealed that the tube with foam-filled provided significantly increment of the energy absorption than that of the empty tube. While the density of foam and D/t ratios increase, the tendency of collapse mode is transformed from asymmetric mode to concertina mode.

“…In order to improve crashworthy of automotive metal structure without increasing too much weight, a metal foam-fill technique was suggested by Y. Yamada et al 1) and W. Yan. 2) Later, C. Thinvongpituk et al 3) also suggested to use Polyurethane foam to fill in tube to gain more specific energy absorption. However, metal is low strength per weight, fatigue and corrosive.…”

This research was aimed to study the effect of fiber orientation and stacking sequence of hybrid tube subjected to axial impact. The specimens were composite AL/GFRP, made of circular aluminum tubes and wrapped with 1, 2 or 3 layers of E-glass/polyester. The specimens were manufactured by hand lay-up technique in vacuum bag. Different ply angles of GFRP fiber which are 0°, 45°and 90°and their combination were applied. Various stacking sequence of GFRP layers were used, forming different types of specimen. Specimens were tested using a vertical impact testing machine with a 30 kg hammer dropped from 2.43 m height to strike the specimens. The results revealed that hybrid tube of AL/GFRP can resist higher impact load than AL tube. The stacking sequence and fiber orientation were found to have influence on failure mode and hence the crashworthiness behavior of specimens. Keeping 90°of fiber ply angle in the outer layer of specimen could to provide highest maximum and also mean loads. The collapse mechanism of each tube was examined in detailed and mode of collapse was also discussed. FEA simulation by ABAQUS μ was also used for detailed investigation and compared to experiment. Good agreement was achieved.
