Abstract
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.
