采用热机械分析、动态热重分析和差示扫描量热法研究了芳香族纤维Arselon、Arselon-C、Arimid和Armos的纺丝态和热处理态的热性能。根据TMA的数据，Arselon、Arselon-C、Arimid和热处理的Armos纤维在高达400°C的温度下保持尺寸稳定性。收缩率不超过1- 2%。初纺Armos纤维的伸长不显著（低于7%）。由TGA和DSC得到的芳香族纤维的温度特性表明，在390-400°C以上的温度下，芳香族纤维的热氧降解开始明显。
The thermal properties of the aromatic fibres Arselon, Arselon-C, Arimid, and Armos, as-spun and heat-treated are investigated using methods of thermomechanical and dynamic thermogravimetric analysis and differential scanning calorimetry. According to the TMA data, Arselon, Arselon-C, Arimid, and heat-treated Armos fibres retain size stability up to 400°C. Shrinkage is no more than 1–2%. As-spun Armos fibres lengthen insignificantly (under 7%). The temperature characteristics of aromatic fibres obtained by TGA and DSC show that thermooxidative degradation markedly begins at temperature above 390–400°C.
