Abstract

Derivative Thermogravimetric analysis under air was used to observe the thermal decomposition process of Chicken feather fiber (CFF) reinforced Poly-lactic acid (PLA) composite filament of 2.2 mm diameter. The thermal degradation of the sample was initiated at 140 ֯C. Approximately 75 % of the thermal degradation occurred between the temperature of 357 ֯C and 399 ֯C. The composite's activation energy was established using the Coats-Redfern method. The results showed that the activation energy of 112.06 kJ/mol is utilized for the sample throughout the temperature range of 23 ֯C to 398 ֯C. A low activation energy is indicative of rapid chemical reactions between the CFF and PLA molecules. The results from TGA and DTGA indicate that the addition of CFF in the PLA matrix enhanced the thermal stability.

摘要

在空气中进行导数热重分析，以观察直径为2.2毫米的鸡毛纤维（CFF）增强聚乳酸（PLA）复合长丝的热分解过程。样品的热降解在140℃开始。约75%的热降解发生在357℃至399℃之间。使用Coats-Redfern方法确定了复合材料的活化能。结果表明，在23℃至398℃的整个温度范围内，样品的活化能为112.06 kJ/mol。低活化能表明CFF和PLA分子之间发生了快速化学反应。热重分析（TGA）和导数热重分析（DTGA）的结果表明，在PLA基体中添加CFF提高了热稳定性。
