The effect of reinforcing natural fiber in the form of woven fabric on dynamic mechanical and thermogravimetric analysis was investigated. Further the influence of water molecule interaction on dynamic mechanical analysis of natural fiber composite were studied. Results revealed that basket type and intra-ply hybridized composites enhances the dynamic mechanical properties of the composites due to the enhancement in modulus by the reinforcement, whereas herringbone composites enhance the loss factor of the composites. It was noticed that, irrespective of the weaving architecture and intra-ply hybridization, composite samples immersed in the water for 45 days affects the storage and loss modulus of the composite and to enhance the loss factor. Thermogravimetric analysis carried out on composites revealed that, compared to weaving architecture, the presence of cellulose and hemicellulose in the fiber cell wall influences the thermal properties of the composites.

研究了机织织物形式的天然纤维增强对动态力学和热重分析的影响。进一步研究了水分子相互作用对天然纤维复合材料动态力学分析的影响。结果表明，篮型和层内杂化复合材料由于增强模量的增加而增强了复合材料的动态力学性能，而人字形复合材料则增强了复合材料的损耗因子。注意到，不管编织结构和层内杂交如何，将复合样品浸入水中45天都会影响复合材料的储存和损耗模量，并增加损耗因子。对复合材料进行的热重分析表明，与编织结构相比，
