Abstrakt: This work used de-oiled cashew nut husk biosilica and ramie fiber to create a new vinyl ester–based biocomposite. This study's main goal was to determine how the silane treatment of biosilica particles and their volume percent affected the characteristics of composite materials. Through a thermo-chemical technique, the biosilica was removed from the deoiled husks of cashew nuts, and the surface of the silane was then treated with 3-aminopropyltrimethoxysilane. According to the findings, adding 3 vol.% biosilica and 40 vol.% ramie fiber (VRS2) resulted in the higher values of tensile strength, flexural strength, compression strength, Izod impact, hardness, and ILSS, which were 147.37 MPa, 178.47 MPa, 18.18 MPa, 5.82 J, and 27 MPa, respectively. Similar to this, increased fatigue life counts for the composite designation VRS2 are seen to be 30,192, 26,073, and 23,884 at 30%, 60%, and 90% of UTS, respectively. Comparing composite designation VRS1 and VRS2, it can be seen that the VRS2 has a higher storage modulus of 6.1 GPa and a lower loss tangent value of 0.5. Due to their enhanced load-bearing capability, time-dependent behavior, and for being lightweight, the products made out of these composites could have less inertia and be easy to construct. Moreover, these environmentally friendly polymer composites could be used in lightweight engineering applications such as automobiles, drones, storage tanks, agriculture products, manholes, and sports gadgets.
