“…Good dispersion of the fibers in the polymer matrix is considered to be an important criteria for obtaining improved mechanical performance. Also at high fiber loading, it is proved that lack of fiber dispersion can result in agglomeration of fibers which has direct effect to reduce the reinforcing potential of the composites [27,28]. Three different materials with varying diameters (e.g., AMFs with $120 lm, SMFs with $10 lm and CNFs with $ 200 nm) were evaluated for their reinforcement efficacy as dental filler.…”

“…Especially in early 20th century a new era has started after the discovery of synthetic resins (polymers) and in the middle of 20 th century the composites evolved as durable and reliable structural elements reinforced with artificial fibers (glass, carbon, aramid fibers), since then the applications of composites traced in every possible sector like automotive, aerospace, marine, defence, biomedical, etc. Further, these artificial fibers can able to offer very high performance when combined with polymers rather than metal alloys or ceramics [1][2][3][4].…”

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.

“…It is necessary to know the fatigue resistance of FRPs to ensure the integrity of the structures. 10 The long-term retention of mechanical properties of FRPs exposed to severe service environment is a major concern in the design of structural applications. 11 To date, the effect of temperature and water/moisture absorption and diffusion on the mechanical properties has been extensively studied.…”

A pultruded carbon fibre core (CFC) and glass fibre shell (GFS) hybrid fiber reinforced polymer (HFRP) rod with the diameter of 19 mm was developed. It was kept immersed in water in a self‐designed pressure chamber device with adjustable hydraulic pressure (20 MPa); after immersion, the tension‐tension fatigue performance was measured at stress levels of 41.7%, 33.4%, and 25.0%. Significant postcuring of resin was observed, resulting in the increase in Tgs for the core and shell layers. There was no significant decrease in the tensile strength of the hybrid rod. The fatigue failure of the hybrid rod was accompanied by debonding of CFC/GFS interface, redistribution of cyclic load, and catastrophic splitting or bursting of GFS. The immersion in water under hydraulic pressure led to a significant increase in fatigue life. The increase in the fatigue life was because of the improvement in interface bonding strength and toughness of the resin owing to the postcuring of the resin. After fatigue, significant degradation in the residual interface bonding strength was observed for the hybrid rods.
