“…Particle cavitations have enhanced the fatigue life of the modified composite; the strength and stiffness of the material were improved by 10.4% and 3.5%. 20 Damage mechanisms such as fiber-matrix interface debonding and nanoparticle-matrix debonding enhanced the fatigue life of reinforced epoxy composite with multi-walled carbon nanotubes. 21 Incorporation of nanoclay in glass fiber-reinforced epoxy composites enhanced the fatigue life of the composites through fiber breakage, which was an additional damage mechanism that occurred after complete delamination in the thick region.…”

The aim of this study is to investigate the influence of nanosilica on glass-reinforced epoxy composites under static mechanical and tension–tension fatigue loading. The glass-reinforced epoxy composites were manufactured with three different concentrations of nanosilica (6, 7, and 8 wt%). Static mechanical tests include tensile, flexure and short-beam strength. 6 wt% nanosilica composites showed the greatest enhancement in tensile strength, percentage elongation, and inter-laminar shear strength compared to the other concentrations and the control. Extensive tension–tension fatigue tests (R-ratio of 0.1 and frequency 2 Hz) were conducted on the control and 6 wt% nanosilica composites. In load-controlled and constant amplitude tests, a percentage of the ultimate tensile strength was applied to the specimens. Stress applied was from 80% of UTS, and reduced in steps of 10% until specimens survived 1 million cycles. In high-cycle and low-cycle fatigue tests, 6 wt% nanosilica composites showed 10 and 3 times improvement in fatigue life, respectively, compared to the control composites. Stiffness degradation curves were explained with three stages of damage mechanisms. The final failure occurred due to fiber breakage in the third stage. Both the control and 6 wt% nanosilica composites survived 1 million cycles at a maximum stress of 46.6 MPa, but at the end of 1 million cycles, control composites lost 65% modulus compared to 45% modulus loss in the 6 wt% nanosilica composites.

“…Due to these material and geometrical discontinuities, a tapered laminate is prone to interlaminar disbond (delamination) between these sub-laminates in the ply drop location, following earlier failure associated with the resin pocket [4,5]. A considerable amount of work has been reported in the literature on the failure mechanisms of tapered laminates under tensile loading [2][3][4][5][6][7][8][9]. As illustrated in Fig.…”

“…Among many artificial fibers especially glass fiber reinforced polymer composites (GFRPs) and carbon firber reinforced polymer composites (CFRPs) are very popular and widely accepted for the commercial applications because of its high strength and stiffness, large fracture toughness and strength, huge fatigue capacities, low density and ease of fabrication [5][6]. Apart from the superior mechanical properties, GFRPs and CFRPs exhibit low cost to performance ratio when compared with Kevlar and aramid reinforced polymer composites.…”

In the present work multi-walled carbon nanotubes (MWNTs), the highly anisotropic, promising nanofillers used as additional structural reinforcement to improve the tensile, fatigue and damping capabilities of glass fiber reinforced composites (GFRP) for the Micro Air Vehicle (MAV) application. Further, the GFRP nanocomposites have been strengthened by making use of strong anisotropy of MWNT’s by aligning them on each layer of GFRP laminate. GFRP nanocomposites have been prepared for very low weight percentage (0.5 wt%) of MWNT, with alignment and without alignment. The alignment has been done with the newly developed in-house electrode-fixture assembly, which can be scalable to any size. The result shows that the alignment of MWNTs on GFRP lamina has a significant effect over GFRP lamina without MWNT alignment and the neat GFRP (without any nano reinforcements) without sacrificing any of the mechanical properties.
