摘要

本研究对来自刚果民主共和国(DRC)的龙舌兰植物纤维进行了表征。进行拉伸试验以确定其机械性能和热重分析(TGA)以确定其热性能。使用工业光学显微镜(Nikon Eclipse LV150,日本)测量光纤直径,考虑3个光纤样品的3个切片在50倍,100倍和200倍的放大倍数下的平均值。此外,ASTM D3379标准用于使用具有5kN称重传感器容量的万能拉力试验机(岛足亲笔AGS-X,日本)来评估拉伸性能。实验以30mm的轨距和1mm /min的十字速度进行。为保证光纤在拉伸机上有足够的固定,光纤提前粘接在宽40mm、长50mm的矩形结构上。在拉伸试验前,将框架的两侧切割以释放纤维样品。进行热重分析以确定纤维的热稳定性。将这些测试和分析的结果与文献中类似的研究进行了比较和解释。

Mechanical and Thermal Characterization of Congolese Agave Sisalana Natural Fibers
In this study, Agave Sisalana plant fibers supplied from the Democratic Republic of the Congo (DRC) are characterized. Tensile test to determine their mechanical properties and Thermogravimetric Analysis (TGA) to determine their thermal properties are performed. Fiber diameter is measured using an Industrial Optical Microscope (Nikon Eclipse LV150, Japan) considering the average value from 3 sections of 3 fiber samples with 50X, 100X and 200X magnification. Furthermore, the ASTM D3379 standard is used in the evaluation of the tensile properties by using a Universal Tensile Testing Machine (Shimadzu Autograph AGS-X, Japan) with a 5kN load cell capacity. The experiment is performed with a 30 mm gauge length and 1 mm/min crosshead speed. To ensure sufficient fiber fastening to the tensile machine, fiber is glued earlier to a rectangular structure of 40 mm in width and 50 mm in length. Both sides of the frame are cut to free the fiber sample before the tensile test. Thermogravimetric analysis is performed to determine the thermal stability of the fibers. The results obtained from these test and analysis are compared with similar studies in the literature and interpreted comparatively.
