Humidity Impact on the Material Characteristics of a Sisal Laminate: The Role of the Rapid Vibrational Method
Main Article Content
Abstract
Natural fabrics have great potential and numerous benefits. Nevertheless, their widespread acceptance has been hampered by a lack of faith in their structural behaviour. Problems include vulnerability to increased water uptake. This research aims to use a novel technique to characterise the influence of hydration on sisal and epoxy synthetic structures. This substance can be employed in the automotive (doors, dashboards, etc.) and construction management sectors. The characterization technique applied is novel and is founded on the impulsive stimulation method. The material properties discovered are similar to all those acquired by traditional characterization techniques such as three-point flexural and shear testing. These data reveal that the increased water content reduces the electrical (frequency range) and mechanical (elastic modulus) characteristics of a sisal/epoxy composite. At bulk saturation, we observed a 10% fall in the required rate and the relative density losing 29% to 48% of its initial value. Furthermore, the temperature in the water baths is used to significantly influence the dispersion rate and the deterioration of mechanical features.
