In this work, flexural properties and failure behavior of unidirectional (UD) carbon fiber reinforced polyamide 6 (CF/Nylon 6) and epoxy resin (CF/ Epoxy) laminates were investigated through three-point bending test. The mechanical properties and failure behavior of 0 and 90 degree CF/Nylon 6 and CF/Epoxy laminates were discussed based on the fiber volume fraction, fiber distribution, void content, interfacial properties, transversal tensile strength and fracture toughness. The effects of fiber volume fraction, fiber distribution, void content and their hybrid effect on the flexural properties were investigated.Step-by-step observation and scanning electron microscope observation of laminates after flexural tests were employed to analyze the fracture process.

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.
