Abstract

Natural plant fibres are increasingly being used in composites as reinforcement due to their favorable environmental considerations. In these composites, the fiber and fabric properties play a significant role in enhancing composite properties. Fiber arrangement is controlled by converting the fiber into yarn and fabric. This optimizes the simplicity with which reinforcement may be handled throughout the production of composites, as well as the fibre alignment. This paper aims at the characterization of woven sisal fabrics. Three different types of woven fabrics were analyzed to comprehend the impact of textile mechanical properties like fabric stretch, flexural strength, tensile strength and recovery in warp and weft directions. All three woven fabrics' tensile characteristics and elongation were found to be better in the weft direction than the warp direction. As the gram per centimeter square increased, the flexural modulus increased as well. Crimp in the warp and weft directions directly correlates to the fabric's stretch and recovery. The bursting strength of the fabric depends on the grams per centimeter square, cover factor, and yarn linear density. Three woven sisal fabrics with cover factors of 53 to 93% in the warp and weft orientations are appropriate for composite reinforcement. The results also reveal that load carrying capacity is enhanced by adding fabric in sawdust bricks and superior strain value. The bending characteristics of the sawdust composites have shown considerable impact on the woven design as well as grams per unit area. Combinative Distance-based Assessment (COMDAS) Multi Objective Optimization Techniques used to study the ranking for sisal fabric mechanical properties.
