Abstract

The goal of this research is to show that epoxy resin (ER) / coir fiber mats (CFM) hybrid composite laminates with nano-silica particle (NP) reinforcement improve mechanical characteristics and water absorption. Lately, it has been employed in automotive, aerospace, and structural industries where coir fiber-reinforced polymers are safe for ecologically friendly composite applications. The Compression - Hand layup technique is used to make the epoxy composites reinforced with natural coir fibres and nano-silica particles in various weight fractions (5, 10, 15, 20 and 25% by weight). Mechanical parameters such as tensile, flexural, compressive, impact strength, thermal conductivity and also water absorption of composites are evaluated in this study. Scanning electron microscopy is also used to analyze the surface morphology of cracked surfaces (SEM). Hybrid nanosilica-coir fiber mat reinforced epoxy resin has decreased water absorption (percent) suggesting better mechanical qualities. Furthermore, the hybrid epoxy-containing 20% nano-silica coir mat improves all the said mechanical properties.

纳米二氧化硅纤维垫增强环氧树脂复合材料的力学、导热性和吸水性

本研究的目的是表明环氧树脂(ER) /椰壳纤维垫(CFM)复合材料层合板与纳米二氧化硅颗粒(NP)增强改善力学性能和吸水性。最近，它已被用于汽车、航空航天和结构行业，在这些行业中，椰壳纤维增强聚合物是安全的生态友好型复合材料应用。压缩-手工叠加技术用于用天然椰胶纤维和纳米二氧化硅颗粒以不同重量分量(按重量计为5、10、15、20和25%)来增强环氧复合材料。本研究评估了复合材料的拉伸、弯曲、压缩、冲击强度、导热系数和吸水性等力学参数。扫描电子显微镜也用于分析裂纹表面的表面形貌。杂化纳米硅-椰子纤维垫增强环氧树脂的吸水率降低(百分比)，表明更好的机械质量。此外，含20%环氧树脂的杂化纳米二氧化硅可改善上述所有力学性能。
