Thermal and Mechanical Behavior of the Coir Powder Filled Polyester Micro-Composites

ABSTRACT

Reinforcement of micro- or nano-fillers is the new key technique to enhance the mechanical properties of polymers. The present work pertaining to the thermo-mechanical behavior of micron range coir filler reinforced polyester matrix composites. The polyester micro-composites are manufactured by hand lay-up method in which the reinforcement is coir micro-fillers, which are uniformly dispersed in the polyester matrix. The following testing and characterizations were performed to predict the thermo-mechanical behavior of the micro-composites and pristine polymer: tensile and flexural tests, Dynamic Mechanical Analysis (DMA), and Field Emission Scanning Electron Microscopy (FESEM). The mechanical properties of micro-composites were attained highest when the filler reinforcements were maximum. Dynamic light scattering (DLS) particle size analysis shown the size distribution of coir micro-particles and the avg. size of coir micro-particles was 0.255 µm.

摘要

微纳米填料的增强是提高聚合物力学性能的关键新技术。本文研究了微米级椰壳填料增强聚酯基复合材料的热力学性能。采用手工铺层法制备了聚酯微复合材料，其中增强体为均匀分散在聚酯基体中的Coir微填料。为了预测微复合材料和原始聚合物的热力学行为，进行了以下测试和表征：拉伸和弯曲试验、动态力学分析（DMA）和场发射扫描电子显微镜（FESEM）。当填料增强量最大时，复合材料的力学性能最高。动态光散射（DLS）粒度分析表明，缪尔微粒的粒度分布和缪尔微粒的平均粒径为0.255 µm。
