| description | In this study, the comparative role of nano‐ and
micro‐sized Cu powder in exploring the influence on the
tribo‐performance of friction materials in the form of
brake‐pads is discussed. Two friction composites were
developed by keeping allthe ingredients constant and
varying the size of the selected filler (copper powder).
The developed micro‐composite contained 10 % (wt) Cu
(400 ‐ 600 μm) while in the nano‐composite only a part (2
%) of the micro‐powder was replaced by a nano‐powder
(50 ‐ 200 nm) since 10 % replacement was not possible
because of the agglomeration problem. One more
composite without any metallic filler was also developed
for the sake of comparison. For tribo‐evaluation, the
brake‐dynamometer testing was selected. The
performance properties, such as friction, wear and
sensitivity of friction towards load, speed and
temperature were studied as per industrial practice. It
was concluded that the inclusion of nano‐Cu powder (just
2 %) improved the performance properties significantly.
Micro‐composite was a moderate performer while
composite without Cu powder proved the poorest. The
quality of a tribo‐layer transferred to the disc as studied
in SEM was confirmed to be one of the reasons for the
improved performance of the nano‐composite. |
