“…These samples were additively manufactured and investigated both experimentally and numerically under quasi-static loading. Morales et al [61] examined the quasi-static and dynamic crashworthiness behaviour of additively manufactured hollow thin-walled structures reinforced with continuous CF-PA and GF-PA under axial and radial loading. Chang et al [62] fabricated the continuous CF reinforced PEEK laminates by using laser-assisted laminated object additive manufacturing technique.…”

Thin-walled energy absorbing structures based on hybrid structural concepts have a lightweight benefit along with great potential of enhancing the crashworthiness characteristics. Inspired by the huge number of research investigations performed on novel additively manufactured hybrid metal-composite configurations and their latest developments, the current review article extensively reports the latest advances along with promising outcomes of the impact response of various additively manufactured hybrid metal-composite structures for crashworthiness applications. Specific consideration is given to the crushing performance of the hybrid structures fabricated from Fused deposition modelling technique. The significant additive manufacturing techniques, their material selections and exceptional customized structural designs explored in recent times are discussed elaborately. Crushing patterns obtained by hybrid energy absorbing structures under various loading conditions are recognized. Furthermore, comparison of various hybrid structures and their latest advances revealed the efficiency of the thin-walled hybrid configuration based on 3D printing techniques in terms of weight reduction, crashworthiness and energy absorption behaviour. This review article will serve as a catalyst to boost the scientific improvement of hybrid energy absorbing structures utilized as passive safety protective devices in modern vehicles.

The recent article investigates the impact of the presence of halloysite nanoclay (HNC) on crashworthiness performance of glass/epoxy energy absorbent composite tubes. Specimens filled with 0,1,2,3, and 4 wt. % of HNC were manufactured via wet-wrapping process and tested under quasi-static axial loadings. The crush load-displacement response, initial crushing load [Formula: see text], average crushing load ([Formula: see text]), crushing force efficiency ( CFE), absorbed energy ( U), and specific absorbed energy ( SEA) for the proposed composites were determined. The crushing behaviors for all specimens were traced. It was indicated that the specimens’ failure mechanisms and the energy absorption capacities of nanofilled glass/epoxy composites are highly dominated by the wt. % of the embedded HNC. The inclusion of HNC enhances the energy absorbing capacities of glass/epoxy composites during the crushing process. Composite tubes filled with 4 wt. % of HNC has the highest load carrying and energy absorption capacities which are, respectively, 32.75 kN and 1110.84 J. So, they are the most suitable materials for energy dissipating elements. The inclusion of 1, 2, 3, and 4 wt. % of HNC to glass/epoxy composite tubes exhibits, respectively, an enhancement of 8.56, 35.76, 37.96, and 53.33% in [Formula: see text] and an enhancement of 169.29, 215.76, 204.60, and 254.19% in the [Formula: see text]. Also, an improvement in the energy absorbing by, respectively, 220.43, 270.09, 249.11, and 320.98% was attended. The purpose of this work is to experimentally study the applicability of HNC in the energy dissipating composite tubular elements.

Multicellular, thin‐walled impact tubes have been intensely studied and used in various engineering fields in recent years due to their lightweight, high performance, ease of application, superior energy absorption, and stable deformation characteristics. In this study, energy absorption, crashworthiness performances, and deformation properties of thin‐walled structures manufactured from polylactic acid (PLA+) and acrylonitrile butadiene styrene (ABS) using fused deposition modeling (FDM) technology were compared under quasi‐static axial compression. Thin‐walled structures consist of multicellular tubes connected by concentric corner‐edge connections with square and hexagonal cross‐sections. Experimental testing outcomes indicate that the energy absorption capacity increases with increasing the number of corners in multicellular structures. The tubes with square wall‐to‐wall (S‐WW) and hexagonal wall‐to‐wall (H‐WW) cross‐sections exhibit superior crashworthiness performance compared to other cross‐sections. Based on the experimental results, the absorbed energy by WW patterned PLA+ square tubes are 19%, 7%, and 46% more than that of wall‐to‐corner (WC), corner‐to‐wall (CW), and corner‐to‐corner (CC) patterned tubes, respectively, while it is 11%, 19%, and 80% more in hexagonal cross‐section tubes, respectively. This study provides an informative reference for easier applicability of multicellular energy‐absorbing structures with 3D‐print and the design of corner‐edge connections of internal connections in multicellular structures.
