| Abstract: | This paper highlights the friction and wear
behaviour of glass-epoxy (G-E) composites with and without silicon carbide
particles (SiCp) filler content as a function of sliding distance, keeping the
sliding velocity and applied load constant. It is seen that the wear rate
increases with increasing sliding distance, but the gradient is not maintained
the same all through. An attempt has also been made to correlate the wear loss
of the worn surfaces using scanning electron microscopic (SEM) observations.
The coefficient of friction is found to be almost same over a wide range of
sliding distance employed. Further, the study indicates that the SiCp-G-E composites show lower coefficient of
friction and lower slide wear loss compared to G-E composites irrespective of
the sliding distance employed. It is found that during the running in wear, the
wear of the resin mix as well as very few broken fibers are noticed. The
breakage of fibers, the matrix debris formation and interface separation take
place at a much later stage (i.e., in the severe wear region). In the steady
state region some of the broken fibers are getting disoriented in the matrix
and also agglomerations of the debris are seen. Other interesting SEM features
have been noticed and discussed taking into account the addition of SiCp filler
content (2.5 and 5.0 wt. %). |
