“…The ultimate tensile strength and the apparent Young's modulus were calculated as reported by. [ 40,41 ] Many researchers, that is, [ 9,19,42–44 ] who worked on the tensile properties of nanocomposites did not use any strain gages in measuring Young's modulus. They just measured the apparent modulus of elasticity and considered it as an indicator.…”

Recently, hybrid nanofillers loading has been utilized to fabricate multifunctional composites. In this study, silica (SiO2) and cobalt ferrite (CoFe2O4) nanoparticles were combined to form a new hybrid composite structure. Nanofilled glass/epoxy hybrid composite laminates were fabricated using hand lay‐up technique. SiO2/CoFe2O4 hybrid fillers were dispersed in epoxy matrix with sonication. The effect of incorporating SiO2/CoFe2O4 hybrid nanoparticles on the mechanical properties of glass fiber/epoxy composites was investigated. The resultant SiO2/CoFe2O4 hybrid nanocomposites showed good mechanical properties as compared to hybrid nanocomposites fabricated by individually loading SiO2 or CoFe2O4 nanoparticles as well as pristine glass fiber/epoxy composite. A visible improvement in the mechanical properties was observed with hybrid nanocomposite that consisted of CoFe2O4/epoxy core layers and SiO2/epoxy skin layers detached with intermediate layers of hybrid SiO2 + CoFe2O4/epoxy. Scanning electron microscopic (SEM) images of tensile and flexural fractured surfaces reveal a good fiber/matrix interfacial bonding.

“…This phase of weight loss completed at 382.8 °C. Compared to existing studies, the graph depicted a similar behavior to a sample of neat epoxy, even though it had 2 wt% of fiber content in it (Srivastava and Pandey 2019). Additionally, the 10wt% untreated fiber epoxy composites lost weight followed by 10 wt% treated fiber epoxy composites and lastly 6 wt% treated fiber with 2 wt% of fly ash epoxy composites.…”

This paper discusses mechanical, morphological, infrared spectral, and thermal properties of fly ash/sugarcane fiber reinforced epoxy polymer composites. Samples were prepared with and without the addition of 2 wt% of fly ash. Sugarcane fiber additions were varied from 0 wt% to 10 wt% (with an increment of 2 wt% for each sample), while the epoxy was used as a binder. A comparative study of these properties was completed on samples with and without the addition of fly ash in the composites. Based on the results obtained, the addition of 2 wt% of fly ash improved the tensile strength and hardness properties but reduced the flexural strength of the composites. Additions of fly ash reduced bubble or void formation in the composites, while toughening the composites and improving adhesion between the fiber and matrix. Samples with 4 w% of fiber and 2 wt% of fly ash composites showed high tensile strength and hardness properties, while 2 wt% of fiber composites showed high flexural strength.

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.
