Effect of black rice husk ash biosilica on mechanical, wear, and fatigue behavior of stacked aloevera/roselle and glass fiber reinforced epoxy composite
Abstract
<jats:title>Abstract</jats:title><jats:p>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 E<jats:sub>12</jats:sub> and E<jats:sub>22</jats:sub> 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 E<jats:sub>2</jats:sub>, E<jats:sub>21</jats:sub> and E<jats:sub>22</jats:sub> outperformed than E<jats:sub>1</jats:sub>, E<jats:sub>11</jats:sub>, and E<jats:sub>12</jats:sub>. In terms of Izod impact toughness and hardness, composite designation E<jats:sub>22</jats:sub> provides maximum increment of about 94% and 5%. The wear resistance of composite E<jats:sub>22</jats:sub> exhibited lower wear loss and COF. The highest fatigue life count of 41,782 was observed for the composite designation E<jats:sub>22</jats:sub> 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.</jats:p>
