Thermal Ageing and Heat Stability Testing
topic
Thermal ageing exposes fabric specimens to elevated temperatures in circulating air ovens for defined periods, measuring tensile strength retention, elongation change, colour shift, and mass loss as functions of temperature and exposure time; Arrhenius analysis of multi-temperature datasets extrapolates accelerated degradation rates to real-use temperature service life predictions.
Role
Predicts the thermal stability and service life of synthetic technical textiles, safety belt webbing, and high-temperature filtration fabrics in applications involving continuous or intermittent elevated temperature exposure, enabling stabiliser selection and service temperature limit specification.
