Mechanical, wear, and fatigue behavior of alkali-silane-treated areca fiber, RHA biochar, and cardanol oil-toughened epoxy biocomposite

High toughness grape seed oil‐epoxy based composite coating material was prepared in this present study with sea urchin (Echinoidea) spike particle (SSP) for weather protection and insect repellent anti rusting coating applications. The main aim of this research was to study the effect of adding SSP along with grape seed oil in epoxy resin composite and their mechanical, thermal and barrier properties. The SSP used in this present study was prepared from marine waste dead sea‐urchin spikes using ball‐milling process. The prepared particles are then silane treated using aminosilane via acid hydrolysis. According to the results of the present study, the hardness values showed an increment of 7% for 4.0 vol% of SSP and 10 vol% of grape seed oil for composite designation EGS4. Similarly, the wear properties showed that the sp. wear rate and COF decreases up to 0.007 mm3/Nm and 0.51 for composite designation EGS4. However, for 10 vol% of grape seed oil and 0.5 vol% minimum mechanical properties were observed. The better thermal stability was observed for composite designation EGS4 whereas the barrier properties increased with 10 vol% of grape seed oil and 0.5 vol% of SSP. Nevertheless it is noted that the addition of SSP reduces the oxygen permeability and marginally increased the water permeability. These mechanically, thermally and barrier properties strengthened epoxy bio composite coating materials could be used in food packaging, medical and household product making applications.

“…Natural fibers as a substitute for glass and carbon fibers in polymer composites have gained the attention of several academics and scientists in recent decades due to their benefits over traditional glass and carbon fibers. [ 1 ] Due to their acceptable mechanical qualities, natural fibers (e.g., jute, banana, sisal, kenaf, aleovera, hemp, bamboo, roselle, and pineapple leaf) are being utilized in place of glass and other synthetic fibers. Natural fibers have several advantages, including, cheap cost, low density, abundant availability, environmental friendliness, renewability, and biodegradability, ease of processing, as well as high specific strength and modulus.…”

In this present study, a high‐performance structural epoxy biocomposite has been prepared and characterized for its mechanical, wear, and fatigue behavior. The main aim of this research was to determine the effect of fiber stacking order and the biosilica addition in the epoxy hybrid composite when it is subjected to external loading. The research also focused on how the surface treatment process on fiber and particle affects the mechanical, wear, and fatigue behavior of composite. The biosilica particles were synthesized from black rice husks and then surface treated with 3‐aminopropyltriethoxysilane. Similarly, a base treatment was applied to fiber mats and the composite laminates for this investigation were fabricated by hand layup process. It is noted that the composite designations E12 and E22 exhibited an improved tensile strength of 58, 62% and flexural strength of 45, 51% for 1.0 vol% biosilica in both staking sequence models. Similarly, in inter‐laminar shear strength the composites E2, E21 and E22 outperformed than E1, E11, and E12. In terms of Izod impact toughness and hardness, composite designation E22 provides maximum increment of about 94% and 5%. The wear resistance of composite E22 exhibited lower wear loss and COF. The highest fatigue life count of 41,782 was observed for the composite designation E22 in tension‐tension fatigue mode. Overall the stacking order R/A/G/A/R gives better results than others. These load bearing properties enhanced hybrid composites might be employed in structural, industrial, automotive, home appliance, defense, and lightweight industrial applications.

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
