Abstract
Introduction
Augmenting concern towards effective utilization of agro waste into useful products has formented the scientific community to look for alternate sources of materials. On a circular economy contemplation, natural fibers extricated from agro waste have a potential headway towards the evolution of newer materials.
Methods
The current research activity is focused on the optimization of influential parameters, namely fiber volume, load, sliding distance and sliding velocity on the wear characteristics of inflorescence fiber-fortified epoxy composites. Coconut Inflorescence fiber is selected as reinforcement material for the present work. NaOH treatment at 5% wt/vol for 1 hour towards removal of amorphous contents present in the fibers. Taguchi-inspired L16 orthogonal array is used for the design of experiments using Minitab software. The control factors chosen for the optimization study are namely fiber content (10 mm, 15 mm, 20 mm and 25 mm), a load of (5 N, 10N, 15 N and 20 N), a sliding distance of (200 m, 400 m, 600 m and 800 m) and sliding velocity of (6 m/s, 12 m/s, 18 m/s and 24 m/s).
Results
The optimal combination of parameters, namely fiber content of 20 wt%, load of 5N, a sliding distance of 600 m and sliding velocity of 24 m/s, contributed to the merest wear rate of 4.328 m3/N.m. Morphological evaluation of the composites revealed agglomeration of fibers in the matrix, thereby, the matrix was not able to transfer load uniformly.
Conclusion
Leading to failure of composites as a result of wear rate increase. Thus, inflorescence fiber-fortified epoxy composites fabricated on the above-mentioned control factors will have better wear rate for futuristic applications.
