“…To date, a considerable amount of literature has been published on the energy absorption characteristics of composite materials affected by many factors, such as fiber and matrix property [12][13][14], fiber orientation [15; 16], hybridization [17], layup [18], geometry dimension and shape [8; 10; 16; 19; 20], trigger mechanism [21][22][23][24][25] and filler [6; 26]. Through these studies, it can be found that the crushed tubes subjected to axial crushing compression deform in various failure mechanisms, involving delamination, crack propagation, fiber breakage, matrix crack, fiber-matrix debond, lamina bundles fracture and bending etc.…”

“…Lastly, splaying failure mode dominated the post-crushing stage as clearly illustrated in Figures 2(d-f). The studies by Oshkovr et al [7] and Eshkoor et al [8] On silk/epoxy tubes showed that generally buckling (either local buckling or mid-length buckling) and hinge formation are the two main characteristics of woven silk/epoxy tubes, displaying a catastrophic failure.…”

In this study, the effects of mandrel geometry on the crashworthiness performance of the fabric plain weave /epoxy hexagonal tubes are investigated. The energy absorption capacity of the tubes is investigated under uniaxial compression. An experimental, the crushing behaviour of composite hexagonally with aspect ratio 70 and different hexagonal angles ranging from 35˚ to 55˚ in 10˚ increment under axial cashing load were considered. The influence of tube side angles on the crashworthiness of (FPWEH) tubes is determined. Compressive testing indicates that the (H.70.45˚) tube provides a specific absorbed energy of 10.7 (kJ/kg), as well as average crushing load, which is the best value compared with other tubes. Furthermore, the failure modes noted as the progressive failure mode, Therefore, this study suggests that FPWEH tubes could be used in several structural applications, i.e. in automotive as energy absorbers and in civil infrastructure as poles.

“…Crushing force efficiency (CFE) is an important factor in measuring crushing performance and evaluating the crashworthiness of energy absorbing parts [41,42]. The crushing force efficiency (CFE) of the composite can be defined as the average crushing load ( m P ) divided by the max crushing load ( i P ) whose value is calculated from the following mathematical Eq.…”

This current study is to investigate the behaviour of the kenaf/wool natural fibre. Reinforced composite elliptical cones with different content of fibre for each of the two types separately in absorbing energy and the load capacity, the lack studies about the composite elliptical tube, our focus was on this shape of shells of effect content of fibre for each of the two types separately. Various fibre contents were considered, including 30 wt%, 35 wt% and 40 wt%. The composite elliptical tubes were subjected to an axial quasi-static crushing test to achieve the study objectives; the methodology has been divided into three main sections concerning the problem statement, the first section is the mandrels preparation; the second section is specimen's fabrication process and finally is the crushing test. This study concerns the usage of the composite elliptical tube as a collapsible energy absorbing device within an automobile structure, which is supported at the distal end (i.e. the point of attachment) by a stronger structure and is designed to behave in a manner more similar to the quasi-static axial regular progressive mode. Therefore, quasi-static axial compression tests were performed on the tubes using INSTRON universal servohydraulic testing machine. The materials used in this study are polymer resin and kenaf/wool fibres. Environmentally friendly kenaf and wool fibre were used in this study due to several advantages such as environmentally benign, lightweight, low cost, no health risk, and availability. Results showed that including 30 wt% has a higher value of load-caring capacity and energy-absorption capability than including 35wt% and including 40 wt%. The results also show that the wool fibre has a higher value of load-carrying capacity and energy-absorption capability than kenaf fibre.
