Studies on the geometrical relationships of plain woven jute fabrics and its application

Purpose This study aims to provide a new and novel method for geometric characterisation of plain woven jute fabrics. Design/methodology/approach This present method is governed by fabric cross-section analysis obtained from optical microscopy. The proposed method bridges the limitations of classical models, providing deeper insights into fabric structure-property relationships. Findings Results revealed higher constants for the relationships between h/p and √c. This study also helps to obtain the fabric volume fraction and resin volume fraction for woven jute fabric reinforced composite. Predicted composite density were 1.15 g/cm3 with 3.36 % error compared to the measure composite density of 1.19 g/cm3. Research limitations/implications Only plain woven jute fabrics were studied. Practical implications These findings highlight the critical role of yarn structure, thickness and areal density in determining the density of jute fabric-reinforced composites. This study establishes a comprehensive and robust framework for the optimization of woven jute fabric composites, thereby advancing the understanding of the underlying architectural principles of composite materials. Originality/value The study introduces a new and novel approach for characterisation addressing the shortcomings of classical models, which can predict the property with a very small deviation from the measured value. This study enhances the scientific understanding of jute fabric structure which contributes to the development of eco-friendly composite materials aligning with sustainable engineering trends.
