摘要

近年来,纺织复合材料因其优异的机械性能、尺寸稳定性和低廉的生产成本而备受青睐。在本分析中,采用手糊法制造了加入或不加入纳米椰壳灰 (CSA) 作为填料的平纹编织碳纤维和 E 玻璃纤维增强复合材料。对制造的复合材料进行了机械性能和热性能测定。同时,通过扫描电子显微镜进行了断口研究,以预测复合材料的不同失效类型。结果发现,当添加 2 wt.% 的 CSA 时,复合材料的机械性能明显提高。含有 2 wt.% 纳米填料的杂化间复合材料显示出最高的拉伸强度(245.96 兆帕)、弯曲强度(496.03 兆帕)和最大降解温度(重量变化率为 81.08%)。内杂交和间杂交编织复合材料的组合显示出最高的抗冲击性,为 3.3 J。内杂交复合材料的假韧性也很明显,显示出中等拉伸应力,为 299.376 MPa,最大伸长率为 5.137 mm。目前的科学研究清楚地表明,将碳纤维置于内部、玻璃纤维置于外部可获得最大的拉伸强度。纳米填料在复合材料中的表面接近和扩散进一步增强了其拉伸性能。在纤维内部和纤维之间交织的复合材料中,剪切分散也导致了最大的能量吸收,而无需使用纳米填料。

Effect of bio nanofiller in influencing the carbon and E-glass fabric reinforced composites
The exceptional mechanical properties, dimensional stability and low cost of production of textile composites have made them quite popular in recent years. In the present analysis, plain woven inter, intra and hybrid carbon and E-glass fibre reinforced composites incorporated with or without nano-coconut shell ash (CSA) as filler were manufactured by hand lay-up method. The mechanical and thermal properties were determined for the manufactured composites. Simultaneously, the fractographic study was conducted by scanning electron microscopy to predict the different kind of failures in composites. The mechanical properties of the composites were found to be significantly better when 2 wt.% of CSA was substituted in it. The inter-hybrid composite containing 2 wt.% nanofiller demonstrated the highest tensile strength of 245.96 MPa, flexural strength of 496.03 MPa and maximum degradation temperature with weight change of 81.08%. A combination of intra- and inter-hybrid woven composite revealed the highest impact resistance of 3.3 J. The pseudo-ductile performance of intra-hybrid composites is also distinctly observed, showing moderate tensile stress of 299.376 MPa and maximum elongation of 5.137 mm. The current scientific effort makes it clear that the greatest tensile strength was obtained by positioning carbon fibres inside and the glass fibres outside. The surface proximity and diffusion of nanofillers in the composites further enhanced their tensile properties. Shear dispersion also led to maximum energy absorption without the need for nanofiller in case of combination of intra- and inter-woven fibre composites.
