“…The adjacent polymer chains are disordered forming interphase zones of different properties. Gurusideswar and Velmurugan [ 55 ] reported that the nano‐modified epoxy resin shows a good wetting to the glass fibers in the interfacial zone than the neat epoxy matrix. Thus, adding nanoparticles into epoxy matrix improves the adhesion between glass fibers and matrix.…”

The present study investigates the effect of halloysite clay nanotubes (HCNT S) on the mechanical properties of glass reinforced aluminum laminate (GLARE) as a very popular fiber metal laminate (FML). GLARE (3/2) with quasi-isotropic lay-up, [Al/[(0 /90)/(45 /−45)]s/Al/[(0 /90)/(45 /−45)]s/Al], filled with different wt% ofHCNTs (0, 0.25, 0.5, 1, 2, and 3 wt%) were fabricated using hand lay-up followed by compression molding. Tensile, flexural, and impact properties of the fabricated GLAREs were evaluated. The failure of the specimens was examined using field emissionscanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDX) and visual inspection. Test results demonstrated that the incorporation of HCNTs improves the mechanical properties of GLARE. Among the studied wt%, the inclusion of 1 wt% of HCNTs to GLARE leads to maximum improvements of 35.67%, 8.50%, 28.85%, 50.47%, 50.27%, 30.43%, and 51.52% in tensile strength, tensile strain, Young's modulus, modulus of toughness, flexural strength, flexural strain, and impact strength, respectively, was attained by adding 1 wt% of HCNTs to GLARE compared to pristine GLARE. Meanwhile, increasing HCNT S content to 3 wt% reverse the trend. FESEM showed that, HCNT S are well dispersed in epoxy. However, a higher weight fraction of HCNT S in epoxy, that is, 3 wt% leads little agglomerations.

“…The shear strength of these nanocomposites was enhanced by 5.5%, 4.9% and 6.3% and shear moduli enhanced by 10.3%, 16%, and 8.1%. Gurusideswar [112] evaluated the effect of nanoclay on tensile modulus of neat epoxy and glass/epoxy composites at low strain rates. The ultrasonication technique disperses the nanofiller in epoxy resin by different wt% (1.5, 3, and 5)%.…”

A recent development in the field of eco-friendly, lightweight and high-performance nanocomposite and a broad range of their innovative applications attract enormous interest in the field of research. However, the search for lighter materials to replace legacy heavy materials in engineering structures especially in automobile and aerospace industries has made the study of tribological properties of epoxy resin based composites significant. Fly ash, from the thermal power plant, is an industrial by-product that can be utilized as filler in epoxy resin with different wt% owing to its distinctive properties like low density, wide availability, good filler factor, good thermal resistance, and glassy nature instead of dumping into the large area of landfills and ash ponds. This review article presents an expanded literature overview on the utilization of industrial waste fly ash, as reinforcement for matrix in making lightweight, high strength composites. In this investigation broaden literature groundwork also covers the effect of nanoparticles on thermal, morphological and mechanical characteristics such as impact strength, tensile strength and flexural strength of fly ash/epoxy nanocomposites.

“…With the increase in filler loading, the composite structure suffers from imperfections such as porosities and voids together with particles agglomerating, as clearly visible in Figure 4 a in 5 wt.% baggage particle-loaded composites. The failure of composites during tensile testing might be caused by the crack initiation from voids or poor interfacial bonding between agglomerated particles and the polymer matrix [16,17].…”

Viscoelastic materials, such as natural fibre-reinforced polymer composites, are strain rate sensitive. In the present investigation, the low strain rate sensitivity (0.00028 s−1, 0.00085 s−1 and 0.0017 s−1) of different sized bagasse particle-reinforced (212 µm and 300 µm) epoxy composites was examined using the Weibull analysis method. The filler loading content was optimized at 2 wt.% to achieve better mechanical properties. Based on the experimental results, it was observed that composites with 212 µm filler particles had higher characteristic strengths, more consistent failure strengths and higher energy absorption properties with higher loading speeds, compared to that of 300 µm filler particles. Based on the mathematical models for particle–matrix interactions, improvements in mechanical properties are attributed to proper filler dispersion and a better fibre–matrix interfacial strength.
