This study illustrates how the mechanical characteristics of a composite may be altered by adding powdered natural fillers such as fish scales or coconut shells. Hand lay-up approach has been used to create the Jute/Basalt hybrid composite with fillers. The epoxy and hardener were combined at a weight ratio of 10:1, and then the natural fillers were added at varied percentages of 3%, 6%, and 9%. The ASTM standards were used for the mechanical test. Fish scale filler has greater tensile and flexural strengths than coconut shell powder, but the latter's impact strength grows with increasing amounts of filler. Jute/basalt composites were also subjected to a water absorption test, the results of which showed that those containing fish scale powder absorbed significantly less water than those containing coconut shell powder.

Dry sliding wear behaviour of Silicon Carbide (SiC) filled glass-jute hybrid epoxy composite has been studied using Response Surface Methodology (RSM) and Taguchi method. RSM developed the regression model for wear loss (WL) and coefficient of friction (COF) as function of sliding velocity, filler content and normal load. Taguchi orthogonal array provided the design of experiment and optimization with sliding velocity, filler content and normal loads, as the control factors with three levels. The ‘smaller-is-better’ characteristic was used to calculate the S/N ratio based on the experimental data. The model accuracy of the developed regression models for WL and COF were obtained. ANOVA analysis was performed to determine the percentage contribution of various control factors on the WL and COF.
