Effects of surface-modified pineapple fibre-reinforced micro B<sub>4</sub>C and CTBN rubber particle toughened epoxy hybrid composites in mechanical, impact damage, thermal and water absorption behavior

Kevlar fiber and brass wire mesh reinforced with cubic boron nitride (CBN) particle-toughened epoxy composites are investigated in this study. This study aims to determine the hybrid composite's mechanical and drop load impact behavior, as well as the effect of surface treatment on the lamina delamination resistance and load bearing phenomenon. The composite laminates were fabricated by hand layup process and characterized according to ASTM standards. The tensile, flexural, Izod impact, ILSS, and hardness testing results shows that adding 35 vol% reinforcements and 3.0 vol% CBN particles indicates the

“…Thus relatively higher energy absorption is observed. [32] It is further noted that adding 0.5 and 1.0 vol% of SiC particle into epoxy resin along with nanoclay particle greatly improved the tear modulus. The presence of high strength and hard SiC particle observes the load effectively and reduces the stress intensity factor of composite's inbuilt flaws.…”

High toughness epoxy resin hybrid composites were prepared using nanoclay, SiC, and glass-caryota intra ply fibers. The main aim of this research was to study the effect of adding Caryota urens natural fiber from biomass as a potential fiber along with synthetic glass fiber in load-bearing and wear properties of nanoclay and silicon carbide (SiC) particle toughened epoxy composite. The intra-ply glass-caryota fiber, silicon carbide, and nanoclay were surface-treated using 3-Aminopropyltrimethoxysilane. The composites were prepared using the hand lay-up method. The tensile result shows that the addition of 1 vol% of the silicon carbide particle along with nanoclay in intra-ply glass-caryota fiberreinforced epoxy composite gives improved results than other composite designations. The wear properties show that the addition of silicon carbide of 1.0 vol% gives a lower specific wear rate of 0.024 mm 3 /Nm. Similarly, the composite, which contains 1.0 vol% of silicon carbide and nanoclay gives higher penetration resistance and energy absorption. In all properties, the addition of silicon carbide modifies the values significantly. This high toughness intra-ply glass-caryota fiber-reinforced silicon carbide/nanoclay toughened epoxy resin composite could be used in automotive, sports components, domestic appliances, and structural body applications.

“…According to author's claim the reinforced 10 vol% of caryota urens fiber as a replacement for asbestos does the job equal to it by improving wear resistance and mechanical properties. Vinoth et al 6 investigates the epoxy composites made of novel morinda‐citrifolia woven fiber. The outcome of research study revealed improvements in mechanical properties and wear behavior for 40 vol% of fiber addition.…”

Novel spinifex littores fiber‐reinforced echinoidea spike particle dispersed epoxy resin hybrid composite has been prepared and characterized. The main objective of this research work was to prepare a new system of epoxy hybrid composite comprises of surface‐treated novel spinifex littores fiber (SLF) and echinoidea spike powder (ESP) for sustainable material development. The fiber was treated with alkali and silane for effective adhesion with matrix. The composites were prepared using hand layup method and post cured at 120°C. The mechanical properties were improved with increasing particle content. The wear result shows a lowest coefficient of friction and sp. wear rate of 0.43 and 0.004 mm3/Nm for SP5 composite designation. Fracture toughness of 32.1 ± 0.69 MPa √m and energy release rate of 1.257 ± 0.071 mJ/m2 was observed for composite designation SP4. A highest fatigue life count of 26,832 was observed for composite contains 1 vol% of silane‐treated ESP and 8 h alkali cum silane‐treated SPF. The fractographs reveals toughness improved matrix phase via shear cup formation. These marine based eco‐friendly reinforcement based epoxy composites could be used in various applications in the cadre of automobile, mini‐aircrafts, structural, sports, and domestic.
