“…The adjacent polymer chains are disordered forming interphase zones of different properties. 52,53,55 According to Kwon et al, 93 the existence of nanofillers could fill in the surface cracks of fiber reinforced composites and increase the radius of the crack tip to avoid the stress concentration. Consequently, the mechanical properties could be enhanced.…”

“…6 Kemapoxy 150 RGL has been effectively used by many authors in their work. [52][53][54][55][56][57][58][59][60][61] HNC, MC, Al 2 O 3 , SiO 2 , and SiC nanofillers were selected for this study due to the availability, good mechanical properties, and being successfully used for reinforcing polymers. In the literature, there is a little work on using the selected nanofillers in…”

Glass reinforced epoxy composite tubes filled with 1, 2, 3, and 4 wt. % of HNC, MC, Al2O3, SiO2, and SiC nanofillers were fabricated using wet-wrapping process by hand lay-up and tested under quasi-static axial loadings. Crashworthiness parameters and failure modes were recorded. Results indicated that EAC and the specimens’ failure modes are dominated by the type and wt. % of the embedded nanofillers. As compared to pristine glass/epoxy tubes, an enhancement of 230.42, 243.30, 286.43, and 336.12% in the absorbed energy ( U) was attained by the addition of 1, 2, 3, and 4 wt. % of HNC, respectively. An improvement of 21.93, 87.35, 225.99, and 318.07% in U was achieved by the inclusion of 1, 2, 3, and 4 wt. % of MC, respectively. An enhancement of 17.66, 51.63, and 71.94% in U was reported by the integration of 1, 2, and 3% of nano-Al2O3. Whilst a reduction of 31.16% was noticed for 4 wt. % of nano-Al2O3. The incorporation of nano-SiO2 and nano-SiC exhibits a reduction in U of the fabricated tubes. Composites filled with 4 wt. % of HNC has the highest load carrying capacity and EAC of 32.75 kN and 1110.84 J, respectively. So, they seem to be the best appropriate choice for energy absorbing elements. Glass/epoxy composite tubes filled with HNC, MC, and Al2O3 show outstanding energy absorption characteristics. However, specimens filled with SiO2 and SiC nanofillers are ineffective in the crashworthiness applications.

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.

The capability of a structure to absorb enormous amount of energy is a crucial issue, particularly for structural components of vehicles, in decreasing the injury in case of collision. The current study investigates the impact of the presence of halloysite clay nanotubes (HNTs) on crashworthiness performance of glass/epoxy energy absorbent composite tubes. Specimens filled with 0, 1, 2, 3, and 4 wt% of HNTs were manufactured via wet‐wrapping process and tested under quasi‐static axial crushing. The crush load–displacement response, initial crushing load Pip, average crushing load (Pavg), crushing force efficiency (CFE), absorbed energy (U), specific absorbed energy (SEA) for the proposed composite tubes were determined and discussed. The crushing behaviors for all specimens were traced. Results indicated that the specimens' failure mechanisms and the energy absorption capacities of nanofilled glass reinforced epoxy composites are controlled by wt% of HNTs. The presence of HNTs improves the energy absorbing capacities of glass/epoxy composites during the crushing process. Composite tubes filled with 4 wt% of HNTs are recommended as energy dissipating elements in vehicles. Weibull distribution was applied to show the failure probabilities and the scatter in the output data. The obtained failure probability graphs are important tools for helping the designers to understand and chose the suitable material for the required design.
