本研究探讨了混合红麻/玻璃纤维增强环氧树脂的能量吸收响应时，受到轴向准静态压缩载荷的混合红麻/玻璃纤维增强环氧树脂的三个堆叠顺序的影响。为了测试和评价混杂复合管的物理和机械性能，将混杂复合管与合成玻璃纤维增强环氧树脂进行了比较。采用自动化纤维缠绕技术制备了混杂和合成复合材料管样品，由于纤维和树脂体积的混合/比例由缠绕速度和纤维张力控制，因此该技术提供了适当的制造程序、质量控制和稳定的过程。从准静态压缩响应的角度探讨了混杂复合材料和合成复合材料圆管的耐撞性机理，以了解其破坏模式、行为和吸能特性。在破碎试验中观察到四种不同的失效模式，纤维/树脂断裂，局部屈曲，脆性断裂和分层。从纤维堆积顺序的角度来看，混杂试件（HTSLIS-A）中纤维体积分数最高，同时增强了渐进破坏的能力，与玻璃纤维增强环氧树脂管相比，初始峰值载荷显著增加28%，能量吸收显著增加68%。同时，玻璃纤维增强管表现出最大的比能量吸收特性，具有最低的初始峰值载荷值和稳定的渐进破碎行为。此外，实验结果表明，红麻纤维可以作为一种潜在的增强材料，在杂交与合成玻璃纤维复合材料作为能量吸收管的应用。(C)2019作者由爱思唯尔公司出版
This study investigates the energy absorption response of hybrid kenaf/glass fibre-reinforced epoxy when subjected to an axial quasi-static compression load with the effect of three stacking sequence of hybrid kenaf/glass reinforced epoxy. To characterise and evaluate the physical and mechanical properties, the hybrid composite tube was compared with synthetic glass fibre-reinforced epoxy. The hybrid and synthetic composites tube sampling were prepared by using automated filament winding technique which it provides the process with a proper fabricating procedure, quality control and stable process due to the mixture/ratio of the fibre and resin volume controlled by the winding speed and fibre tension. Crash- worthiness mechanism of hybrid and synthetic composite tubes specimen were discussed to understand failure modes behaviour and energy absorption characteristics in term of quasi-static compressive response. Four different failure modes were observed in crushing tests as fibre/resin fracturing, local buckling, brittle fracturing and delamination. In the view of fibre stacking sequence aspect, fibre volume fraction in the hybrid specimen (HTSLIS -A) is a highest compared to other specimen and at the same time alleviates the capabilities in progressive failure with the significant increase 28% of initial peak load and 68% of the energy absorbed compared to the glass fibre-reinforced epoxy tube. Meanwhile, the glass fibre-reinforced tube showed the greatest specific energy absorption characteristics with the lowest initial peak load value with stability in progressive crushing behaviour. Also, experimental results have showed that kenaf fibre could be utilised as a potential reinforcement material in hybridisation with synthetic glass fibre composites as energy absorption tube application.
