Quantifying the Uncertainty Associated with the Material Properties of a Natural Fiber

Nowadays, natural fibers have earned a great deal of attention because they help produce eco-products. Since natural fibers grow naturally and their microscopic structures cannot be controlled, their material properties exhibit a great deal of variability. This variability or uncertainty must be known beforehand to ensure the reliability of a natural-fiber-based product. In this article, we use a widely used natural fiber collected from a plant called jute to perform the tensile tests, and, then, to determine the tensile strength and modulus of elasticity. We also quantify the uncertainty associated with abovementioned material properties using both statistical and logical approaches. Finally, we describe the design implications (while designing structure elements using jute fibers) of the quantified uncertainty.
