In this research, nanoclay used as filler in sugar palm‐reinforced composites was investigated by the physical, thermal, and dynamic mechanical properties. Various concentrations of nanoclay were used to fabricate composites by using hand lay‐up technique, followed by hot compression molding with naturally woven sugar palm fiber‐reinforced in polyester matrix. Among various weight concentrations such as 1–5% of nanoclay, it was found that 2% nanoclay‐filled composite (NC) demonstrated the best balance of thermomechanical properties and significantly enhanced the composite. DMA demonstrated that 2% nanoclay content resulted in improved viscoelastic behavior and higher glass transition temperature (T_g) of the composites. TGA also showed improvement in properties, whereas 3% nanoclay‐filled composite showed superior onset temperature, and 5% nanoclay‐filled composite exhibited highest remaining residue. The nanoclay filler was very effective to fill the porous structure and maintain the thickness stability. The thickness swelling was reduced with increasing amount of nanoclay in composites. Overall, the addition of nano clay improved thermal and physical properties of sugar palm‐reinforced polyester composite. J. VINYL ADDIT.

糖棕纤维/聚酯纳米复合材料：添加纳米粘土填料对热，动态机械和物理性能的影响

在这项研究中，通过物理，热和动态力学性能研究了纳米粘土用作糖棕增强复合材料的填料。通过手工铺层技术，使用各种浓度的纳米粘土来制造复合材料，然后通过在聚酯基质中增强的天然编织的糖棕榈纤维进行热压成型。在各种重量浓度（例如1-5％的纳米粘土）中，发现2％的纳米粘土填充复合材料（NC）表现出最佳的热机械性能平衡，并显着增强了复合材料。DMA显示2％的纳米粘土含量可改善粘弹性并提高玻璃化转变温度（T _g）的复合材料。TGA还显示出性能改善，而3％纳米粘土填充的复合材料显示出较高的起始温度，而5％纳米粘土填充的复合材料显示出最高的残留量。纳米粘土填料对填充多孔结构并保持厚度稳定性非常有效。随着复合材料中纳米粘土含量的增加，厚度膨胀减小。总体而言，纳米粘土的添加改善了糖棕榈增强聚酯复合材料的热性能和物理性能。J.乙烯基添加物。TECHNOL。，26：236–243，2020.©2019塑料工程师协会
