Study of mechanical properties and performance of aging hemp fibers

摘要: The weathering of hemp fiber influences their appearance and mechanical properties. aim this study is to better understand the mechanism aging exposed different conditions (moisture, heat UV aging). A xenon test machine was used simulate accelerate natural ageing. influence each condition on properties investigated by micro tensile tests. microstructures water absorption these fibers were analyzed means SEM gravimetric methods. Humidity depends relative humidity, not concerning temperature. Temperature accelerates saturation fibers. All process reduced After 4 weeks exposure, aged has worst compared humidity temperature aging.
