In this article, flexural, impact and dynamic mechanical properties of the Pineapple leaf fibres (PALF) and Washingtonia trunk fibres (GW) based bio-phenolic hybrid composites were examined. The pure and hybrid composites were fabricated using the hand lay-up technique with an overall fibre weight ratio of 50% in which GW and PALF were maintained in the fibre weight ratios of 50:50, 30:70, and 70:30 denoted as 1G1P, 3G7P, and 7G3P, respectively. Hybrid composites displayed better flexural strength, flexural modulus and impact strength than the GW composites and better viscoelastic properties than the PALF composites. Results revealed that 1G1P hybrid composites exhibited 25% and 12% improvements in flexural strength and modulus compared to the GW composites. 3P7K composites showed a twofold increase in impact strength than GW composites. The storage modulus of the pure and hybrid composites declined rapidly beyond the glass transition temperature. Furthermore, it was observed that the values of storage modulus for all the composites at 150 °C were similar regardless of the composite configuration. The Peak of loss modulus was found to increase in the following order: GW > 7G3P > 3G7P > 1G1P > PALF. Furthermore, the temperature at the peak tan delta was improved, and a reduction in the tan delta peak was observed for hybrid composites compared to the pure composites. Finally, the PALF and GW hybrid combinations can be suitable for use in various applications such as textiles, machinery part production industries, medicine, automobiles, etc.

菠萝叶/华盛顿树干纤维基生物酚类杂化复合材料的力学、形态和动态力学分析

本文研究了基于菠萝叶纤维 (PALF) 和华盛顿树干纤维 (GW) 的生物酚醛混合复合材料的弯曲、冲击和动态力学性能。纯复合复合材料和混合复合材料采用手糊工艺制造,总纤维重量比为 50%,其中 GW 和 PALF 保持在 50:50、30:70 和 70:30 的纤维重量比,表示为分别为 1G1P、3G7P 和 7G3P。混合复合材料的弯曲强度、弯曲模量和冲击强度比 GW 复合材料好,粘弹性比 PALF 复合材料好。结果表明,与 GW 复合材料相比,1G1P 混合复合材料的弯曲强度和模量分别提高了 25% 和 12%。3P7K 复合材料的冲击强度是 GW 复合材料的两倍。纯复合材料和杂化复合材料的储能模量在超过玻璃化转变温度后迅速下降。此外,观察到所有复合材料在 150 °C 下的储能模量值相似,无论复合材料配置如何。发现损耗模量的峰值按以下顺序增加:GW > 7G3P > 3G7P > 1G1P > PALF。此外,与纯复合材料相比,杂化复合材料的 tan delta 峰值温度得到改善,并且观察到 tan delta 峰值降低。最后,PALF 和 GW 混合组合可适用于各种应用,如纺织、机械零件生产行业、医药、汽车等。观察到所有复合材料在 150 °C 下的储能模量值是相似的,无论复合材料配置如何。发现损耗模量的峰值按以下顺序增加:GW > 7G3P > 3G7P > 1G1P > PALF。此外,与纯复合材料相比,杂化复合材料的 tan delta 峰值温度得到改善,并且观察到 tan delta 峰值降低。最后,PALF 和 GW 混合组合可适用于各种应用,如纺织、机械零件生产行业、医药、汽车等。观察到所有复合材料在 150 °C 下的储能模量值是相似的,无论复合材料配置如何。发现损耗模量的峰值按以下顺序增加:GW > 7G3P > 3G7P > 1G1P > PALF。此外,与纯复合材料相比,杂化复合材料的 tan delta 峰值温度得到改善,并且观察到 tan delta 峰值降低。最后,PALF 和 GW 混合组合可适用于各种应用,如纺织、机械零件生产行业、医药、汽车等。与纯复合材料相比,混合复合材料的 tan delta 峰值温度得到改善,并且观察到 tan delta 峰值降低。最后,PALF 和 GW 混合组合可适用于各种应用,如纺织、机械零件生产行业、医药、汽车等。与纯复合材料相比,混合复合材料的 tan delta 峰值温度得到改善,并且观察到 tan delta 峰值降低。最后,PALF 和 GW 混合组合可适用于各种应用,如纺织、机械零件生产行业、医药、汽车等。
