Abstract

In this study the mechanical and erosion wear behavior of bamboo fiber reinforce epoxy composites filled with Cement By-Pass Dust (CBPD) were studied. The effect of CBPD content and alkalization on the various properties of these composites was also investigated. Taguchi’s orthogonal arrays are used for analysis of experiential results. It identifies significant control factors influencing the erosion wear and also outlines significant interaction effects. Analysis of variance (ANOVA) test has also been performed on the measured data to find the most significant factors affecting erosion rate. Finally, eroded surfaces of both untreated and alkali treated bamboo fiber reinforced composites were characterized using SEM.

Highlights

  • Over the last decade there has been renewed interest in the use of natural fibers to replace synthetic fibers in composite applications

  • In this study the mechanical and erosion wear behavior of bamboo fiber reinforce epoxy composites filled with Cement By-Pass Dust (CBPD) were studied

  • It is observed from the figure that the void fraction of untreated composites increases with increase in filler content

Summary

Introduction

Over the last decade there has been renewed interest in the use of natural fibers to replace synthetic fibers in composite applications. Compared with conventional fibers natural fibers have many advantages like renewable, environmental friendly, low cost, lightweight, high specific mechanical performance. Bamboo has numerous advantages over other natural fibers such as its availability, excellent mechanical properties in comparison with its weight due to longitudinally aligned fibers, one of the fastest renewable plants etc. Cement By-Pass Dust (CBPD) is a by-product of cement manufacturing It is a fine powdery material similar to Portland cement in appearance. As the raw materials are heated in the kiln, dust particles are produced and carried out with the exhaust gases at the upper end of the kiln. Other compounds include SiO2, Al2O3, Fe2O3, K2O, Na2O, etc To this end, the present research work is undertaken to study the mechanical and erosion wear behavior of bamboo fiber reinforce epoxy composites filled with Cement By-Pass Dust (CBPD) were studied. Analysis of variance (ANOVA) test has been performed on the measured data to find the most significant factors affecting erosion rate
