摘要
本研究评估了环氧树脂复合材料中未加工和碱处理过的 Borassus Flabellifer (BF) 纤维的影响。研究考察了拉伸强度、伸长率和抗冲击性等机械性能，以衡量 "无人驾驶飞行器"（UAV）起落架的承载能力和对突发力的适应能力。傅立叶变换红外衰减全反射（ATR-FTIR）用于确认碱处理前后纤维的成分。扫描电子显微镜（SEM）分析探测了复合材料的微观结构，揭示了纤维与基体之间的相互作用和整体形态。能量色散 X 射线分析（EDX）可深入了解元素组成，有助于理解元素分布和纤维-环氧基质之间的相互作用。热重分析（TGA）显示了所制备环氧树脂复合材料的热稳定性。对吸水性能进行了评估，以衡量耐湿性，这对于在潮湿条件下的耐用性至关重要。这些研究结果为无人机起落架应用提供了有关机械性能、扫描电子显微镜显微结构、EDX 元素组成和吸水性的重要数据。对变形结果的综合研究表明，Borassus Flabellifer (BF) 复合材料在无人机起落架应用中表现优异，超过了香蕉/环氧、菱形/环氧和椰壳/环氧复合材料。在 100 N 负载下，起落架的变形量为 1.50 mm，这些结果凸显了增强无人机设计可持续性的潜力。本研究的结果可为开发更环保、更可持续的无人机铺平道路，以满足快速增长的无人机行业的关键需求。
Investigating the impact of epoxy Borassus flabellifer fiber-based composites for UAV landing gear
This study assesses the impact of raw and alkali-treated Borassus Flabellifer (BF) fibers in an epoxy composite. It examines mechanical properties such as tensile strength, elongation, and impact resistance to gauge load-bearing capacity and resilience to sudden forces in “unmanned aerial vehicle” (UAV) landing gear. Attenuated total reflectance for Fourier transform infrared (ATR-FTIR) were taken to confirm the composition of fiber before and after alkali treatment. Scanning electron microscope (SEM) analysis probes the composite microstructure, shedding light on fiber-matrix interaction and overall morphology. Energy dispersive X-ray analysis (EDX) offers insights into elemental composition, aiding comprehension of element distribution and fiber-epoxy matrix interplay. Thermogravimetric analysis (TGA) showed the thermal stability of the prepared epoxy composites. Water absorption properties are evaluated to gauge resistance to moisture, vital for durability in humid or wet conditions. These findings provide vital data on mechanical properties, SEM microstructure, EDX elemental composition, and water absorption for UAV landing gear applications. The comprehensive investigation of deformation results indicated that Borassus Flabellifer (BF) composite performed exceptionally well for UAV landing gear applications, surpassing banana/epoxy, sisel/epoxy, and coir/epoxy composites. With a landing gear deformation of 1.50 mm under 100 N load, these outcomes underscore the potential for enhancing sustainability in UAV designs. The findings of this study can pave the way for the development of more environmentally friendly and sustainable UAVs to address the critical needs of the rapidly growing UAV industry.
