“…Many papers in the literature discussed the different factors which can affect energy absorption capability and crashworthiness performance of composite structures. These factors are such as the properties of the fiber and resin, fiber orientation, fiber and resin contents, filler, specimen shape, geometry and dimensions, lay‐up, trigger mechanism, and the fiber hybridization .…”

This article provides an experimental investigation into the crashworthiness of carbon–jute–glass reinforced epoxy circular composite tubes. The test specimens were fabricated of 6 layers with different stacking sequence using wet‐wrapping process and tested under uniaxial quasi‐static compression loading up to complete crushing. The effects of hybrid reinforcement, stacking sequence, and relative reinforcement amounts on the energy absorption capabilities and failure modes were studied. Also, the crush load–displacement response, initial crushing failure load, total energy absorption, specific energy absorption, average crushing load, and crushing force efficiency were determined and discussed. The scanning electron microscope study was considered to analyze the failure modes of the crushed specimens. Results indicate that specimens' failure modes and energy absorption capabilities were highly dominated by the reinforcement combinations and plies stacking sequence. Also, hybrid carbon–jute–glass reinforced epoxy composite tubes have the potential to be used as energy absorbers as compared to jute‐reinforced epoxy composite tubes. The JGC composite tube has a higher load carrying capacity and energy absorption capability compared to other hybrid composite tubes, so it seems to be the best appropriate choice for energy absorbing devices.

“…Where h is the thickness of the bundle and Lu is the undulation length-assumed equal to 8h on the basis of the studies by Zhang [34], and Jensen [46] report values between 6 and 10. The inclination angle β (x) of the undulating fibre bundle is given by the equation: (5) The elastic constants of the FCU region are determined by the following formula:…”

“…The effect of winding angle on the strength of FWC subjected to combined external pressure and axial compression was studied by Mistry [4], and the result show that in the case of hydrostatic external pressure loading, the optimum angle is close to 80° instead of 55° reported elsewhere for internal pressure loading [3]. The collapse characteristics and energy absorption capability of FWC with different fibre orientation and wall thickness were studied under axial quasi-static and impact crushing conditions by Wang [5], the fibre orientation and wall thickness were found to have significant influences on energy absorption performance. Martins [6] [7] [8] performed a comparative study between two typical loading conditions (closed-end and restrained-end Full Article conditions) in the pipeline manufactured by FWC tubes.…”

The occurrence of fibre crossover and undulation(FCU) is inherent of the filament windingproc ess .However, the study on the effect of FCU on the mechanical performance and failure of filament wound composite(FWC) structure were mainly experimental research. So in this paper, a macro-meso failure analysis model for FWC considering FCU is established based on Puck, Hashin failure criterion and Linde stiffness degradation model. The influence of fibre crossove r and undulation on the stiffness failure is calculated and analyzed. The numerical results show that the strain in FCU region is higher by about 1.07-1.13 times than it in laminate region, the FCU have a certain influence on the failure strength of filament wound composite and the failure position of FWC under axial tensile load and internal pressure is mainly located FCU region and the failure position under axial compressive load is related to the winding angle.

“…The effect of fiber orientation was studied in numerous papers, [3,18] and experimental tests were applied considering the orientations of 15/−75 , [19] 15 , 45 , and 75 . [20] It was observed that the tube with the fiber orientation of 15 can reach the highest amount of specific energy absorption.…”

Numerical study of the effect of torsional fatigue loading on the energy absorption of composite tubes

A three-dimensional finite element model is developed to predict the effect of torsional fatigue loading on the energy absorption of unidirectional carbon/epoxy (AS4/3501-6) composite tubes. Progressive fatigue damage model for fatigue loading and progressive failure model for axial velocity impact are implemented separately in the Abaqus software through user subroutine VUMAT. Each model is validated by the experimental data available in literature and good agreement is observed between the simulation results and experimental data. Then, these two models are sequentially applied to the composite tube with three different layups.The tube is first placed under torsional fatigue loading and a number of predefined loading cycles is applied. During this loading, the mechanical properties of the material are degraded based on sudden and gradual material properties degradation rules. Next, the fatigued tube is placed under axial impact loading. The resultsshow that by increasing the number of fatigue cycles, the tube's ability to absorb energy is first reduced uniformly but in a particular cycle, due to the sudden drop in the shear mechanical properties of the material, the amount of energy absorption drops sharply and the tube loses its ability to absorb energy before it's catastrophic fatigue failure.
