The Relation Between the Tensile Strength of Ramie (Boehmeria Nivea) Yarn and Its Gauge Length

The chapter investigates the tensile strength of ramie yarn in relation to its gauge length, shedding light on the challenges posed by the high variability in mechanical properties of natural fibres. Through a detailed examination of ramie fibres under tensile loading, the study reveals how gauge length affects tensile strength and strain, with longer lengths exhibiting decreased strength due to increased defects. The research highlights the progressive fracturing of ramie yarn, a beneficial characteristic for structural safety, and the importance of considering variability in tensile strength when designing with ramie yarn. The findings offer crucial insights into the potential of ramie fibres as a sustainable reinforcement material in composite structures, addressing the need for reliable mechanical property characterization in natural fibres.
