摘要

This work seeks to develop a lightweight hybrid biocomposite for UAVs, consisting of birch and Khusha grass fibers with tamarind-derived cellulose embedded in a vinyl ester matrix. This Researchers examined fatigue, low-velocity effect, and mechanical properties of the hybrid composites concerning influence of cellulose particles and the silane treatment on the fibers. Biocomposite was fabricated accompanied by cellulose loadings varied from 1 to 5 vol% utilizing hand lay-up method. Materials comprising 5 vol% cellulose exhibited enhancements in impact strength (6.5 J), tensile strength (155 MPa), flexural strength (220 MPa), interlaminar shear strength (20.4 MPa), and hardness (80 shore-Durometer). The fatigue life measurements increased to 43084.98, 30124.44, and 18182.47 at 30%, 60%, and 90% of UTS, respectively, in the biocomposite containing 3 vol% cellulose. A comparable enhancement in low velocity effect toughness 11.11 J was observed in composite reinforced with 3 vol% cellulose. The results demonstrate that these mechanically reinforced and highly durable biocomposites possess the potential for deployment in diverse sectors, including residential infrastructure, automotive transportation, and unmanned aerial vehicle (UAV) structures within the aerospace industry.
