Experimental, analytical and numerical analysis to investigate the tensile behaviour of hemp fibre yarns

摘要

Natural fibre reinforced composites are emerging as the alternative of synthetic composite materials in several applications due to their limited recyclability and biodegradability. In this study, the tensile behaviour of hemp yarns detached from taffeta and serge fabrics were investigated. Experimental analysis was performed to characterize the crimped yarn properties. Analytical analysis was carried out in order to model and predict the mechanical behaviour of hemp fibre yarns under tensile loading. An inverse optimization approach was also adapted to optimize the mechanical properties of the yarns numerically.
