Aramid and aramid copolymer fibres are used in a wide variety of military and civilian applications; however, the effects of environmental exposure on mechanical properties are still not well understood. This paper analyzes the changes of Aramid 1414's mechanical properties after its exposure to high temperatures, chemical solvents and sunlight, and then compares them with the properties of poly (p-phenylene benzobisoxazole) as-spun and polysulfonamide fibres. The experimental results suggest that the overall environmental resistant performance of aramid filaments is better than poly (p-phenylene benzobisoxazole) as-spun and polysulfonamide materials, some conclusions are put forward for the applications of aramid filaments.
