Mechanical behavior of woven natural fiber fabric composites: Effect of weaving architecture, intra-ply hybridization and stacking sequence of fabrics

Abstract

A comprehensive analysis carried out on the mechanical and free vibration properties of woven natural fiber polymer composites is presented. Jute fabric with three different weave types (plain, basket and herringbone) and intra-ply woven jute-banana fabrics are considered for investigation of the effect of weave type of a fabric and its stacking sequence on mechanical, dynamic mechanical and free vibration properties. Enhancement of the properties is found with the number of layers of fabric and better properties obtained for four layers. Uniform stress distribution along warp and weft direction of fabric with basket weave type lead to better properties compared to other weave types for four-layered composites. Intra-ply hybridization of jute-banana also enhances the mechanical properties but slightly less than the jute-basket fabric composite. The investigations on effect of layer sequence of fabrics revealed improvement in mechanical properties. Layered composite with relatively strong intra-ply fabric as the facing layer and relatively weak jute plain fabrics as the core layer has higher tensile and flexural properties. Experimental modal analysis carried out on beam-like composite laminates reveal that natural frequencies and associated modal damping factor are significantly influenced by stacking sequence and weave type of a fabric. The density of the composite calculated based on Archimedes principle matches well with the theoretical values.

A comprehensive review on the vibration and damping characteristics of vegetable fiber-reinforced composites

“…As different to above studies, Rajesh et al. 33 have investigated the effect of number of layers and stacking sequence on free vibration properties polyester matrix composites of woven jute, banana fabrics. Results show that vibration characteristics were best for four-layered composites compared to one-, two-, and three-layered composites.…”

Effect of Surface Modification on Mechanical Properties of Buri Palm (Corypha Utan) Fibre Composite Reinforcement

“…Rajesh and Pitchaimani [13] discovered a stacking sequence to affect the flexural strength of two different layers of jute fibre, whereby a four-layer jute fibre is higher than three-layer jute fibre composite. Rajesh et al [14] studied the mechanical behaviour of woven natural fibre fabric composite, and indicated that a fourlayer plain weave fibre gave the highest mechanical performance as compared to one-layer, two-layer, and three-layer jute fibre. A study by Sathishkumar et al [15] found that the composite mechanical properties were increased by increasing the number of layers.…”

“…This treatment capable of increasing the surface roughness by removed a certain amount of cellulose, lignin, wax and oil content at the external fibre surface. The rough surface fibre is known to have better mechanical interlocking [13][14][15]. Alawar et al [19] who analysed the characteristics of treated date palm tree fibre revealed that treatment with 1% concentration NaOH for 1 h at 100°C was the ideal treatment.…”

Hierarchical framework for quantifying multiscale structures of two-dimensional woven carbon fibre-reinforced composites considering geometric variability

“…Finally, the moulding process will alter the relatively regular structures due to the forced displacement of moulds. As is widely recognized, the properties of composites are directly decided by the microstructures [8–10]. In order to improve the accuracy of multiscale FE modelling of CFRP, the primary task is to establish geometric structures of representative domains as closer to realistic geometric characteristics as possible.…”
