Abstract This study examined cantala fiber (CF) that was subjected to fumigation treatment to increase interfacial shear strength (IFSS) and fiber mechanical properties. The CF was fumigated for 0 h, 5 h, 10 h, and 15 h using coconut skin for fumigation at a temperature of ±60 °C. X-ray diffraction was performed, and the crystallinity index (Cr.I) increased after fumigation. Thermogravimetric Analysis (TGA) and derivative TGA revealed a decrease in hemicellulose content. Scanning electron microscopy (SEM) results showed that fumigation treatment for up to 10 h resulted in a cleaner CF surface. The contact angles of water and ethylene glycol with CF were measured, and the results showed that the contact angle decreased with increased treatment time and increased wetting. The resulting IFSS showed that the interaction between the CF and the matrix increased with fumigation treatment. Testing of the tensile strength and modulus of elasticity of composites with unsaturated polyester matrix and Microcrystalline Cellulose (MCC) showed that fumigation treatment for 10 h produced the best results.

微晶纤维素和熏蒸处理复合增强卡塔拉纤维(CF)力学特性的实验研究

摘要 本研究检测了经过熏蒸处理以提高界面剪切强度 (IFSS) 和纤维机械性能的康塔拉纤维 (CF)。使用椰子皮在±60°C 的温度下熏蒸CF 0 小时、5 小时、10 小时和15 小时。进行 X 射线衍射,熏蒸后结晶度指数 (Cr.I) 增加。热重分析 (TGA) 和衍生 TGA 显示半纤维素含量减少。扫描电子显微镜 (SEM) 结果表明,长达 10 小时的熏蒸处理导致 CF 表面更清洁。测量了水和乙二醇与 CF 的接触角,结果表明接触角随着处理时间的增加和润湿性的增加而减小。由此产生的 IFSS 表明,CF 和基质之间的相互作用随着熏蒸处理而增加。对具有不饱和聚酯基体和微晶纤维素 (MCC) 的复合材料的拉伸强度和弹性模量的测试表明,熏蒸处理 10 小时产生了最好的结果。
