The deformation of SVM aromatic polyamide fibres in the temperature range from room temperature to 400°C was investigated by thermomechanical analysis and dilatometry. In the first heating, fibres which had not been thermally drawn were characterized by self-elongation along the axis of orientation and transverse shrinkage, while thermally drawn fibres were characterized by shrinkage in two directions at temperatures below 200°C and self-elongation at higher temperatures. Self-elongation and transverse expansion were observed on repeated heating for both types of fibres in the investigated temperature region.
