Abstract

Nowadays, composites made of plant-based fibers may be used to polymer resin synthetic fiber reinforced composites since they are less expensive, renewable, abundant, less abrasive, and lightweight. Echinatus fiber obtained from the stem of the echinatus plant in an abundant amount. The main objective of this study was to develop echinatus polyester-resin fiber reinforced composite material and investigate its flexural strength, hardness and tensile strength. Echinatus plant was collected and echinatus fiber was extracted by the decortication process from the echinatus plants manually, and treated with 5% NaOH for the improvement of bond and interfacial shear strength. And then, the test specimens were manufactured using a mass fraction with 0 , 45 and 90 orientations using technique of hand lay-up. The tensile strength, hardness, and flexural strength were investigated using samples that were prepared according to the ASTM standards. 70% echinatus fiber to 30% polyester composite material with 0 orientation was found as the material with maximum tensile strength of 60.60 MPa, flexural strength of 96.8 MPa, and hardness values of 44.54 HRA. Considering the mechanical properties’ experimental results, echinatus fiber-reinforced composite with 70% fiber at 0 orientation can be good substitutes for synthetic materials.

聚酯树脂棘草纤维增强复合材料拉伸、弯曲和硬度性能的试验研究

目前，植物纤维复合材料具有价格低廉、可再生、储量丰富、磨耗小、重量轻等优点，可用于聚合物树脂合成纤维增强复合材料。棘果纤维从棘果属植物的茎中提取，含量丰富。本研究的主要目的是研制棘草聚酯-树脂纤维增强复合材料，并对其抗弯强度、硬度和抗拉强度进行研究。采集棘毛虫，采用人工去皮法提取棘毛虫纤维，用5% NaOH处理，提高棘毛虫黏结和界面剪切强度。然后，采用手工铺层技术，采用0、45和90取向的质量分数制备试样。使用根据ASTM标准制备的样品进行拉伸强度、硬度和抗弯强度的研究。结果表明，70%棘毛虫纤维与30%聚酯0取向复合材料的抗拉强度为60.60 MPa，抗折强度为96.8 MPa，硬度值为44.54 HRA。从力学性能的实验结果来看，0取向70%纤维的刺竹纤维增强复合材料可以很好地替代合成材料。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
