	abstract = {Para-aramid fibres possess excellent properties, including high modulus, high strength, and high-temperature
resistance, making them highly practical and cost-effective reinforcement materials. To further analyse the usage
performance of para-aramid fibres under extreme conditions and explore their degradation behaviour and mechanisms
at high temperatures, this paper investigates para-aramid fibres through high-temperature annealing. Various tests,
including thermogravimetric analysis, infrared spectroscopy, X-ray diffraction, Ubbelohde viscometry, and universal
material testing, were employed to analyse changes in the thermal degradation temperature, molecular structure, and
mechanical properties of para-aramid fibres. Tests have shown that after high-temperature treatment of para-aramid
fibres, different protruding particles and pits appear on the surface of the fibres, and the molecular structure gradually
undergoes cleavage and cross-linking. This results in varying degrees of increase in the crystallinity, intrinsic viscosity,
and apparent grain size of crystal planes in different directions of the para-aramid fibres with rising temperatures. On
the other hand, the degree of orientation, the rate of the second type of lattice distortion, thermal performance, and
mechanical properties show a declining trend. The thermal degradation conforms to the kinetics of a second-order
reaction.},
