Grey-Taguchi technique statistical investigation of the mechanical characteristics of hybrid composites made of wood and jute fiber

Abstract

Nowadays, composites are used because they are easy to manufacture and have qualities such being lightweight, non-abrasive, non-flammable, and non-harmful. This article aims to create natural fiber-reinforced polymers with good mechanical qualities based on wood and jute. The necessary composite materials were created using hand layup technique. The Gray-Taguchi approach was used to choose the following three parameters at three distinct levels for composite development: (i) wood density; (ii) wood weight ratio; and (iii) woven jute kind. To estimate the compressive, double shear, and hardness parameters of the manufactured laminates, mechanical testing was conducted in accordance with ASTM guidelines. Nine investigative trials were carried out using the L9 orthogonal array of the Grey Taguchi approach. Based on the Analysis of Variance, determined to be the most important factor improving the mechanical strength of hybrid composites
