Investigation of Possibility of Using Lignocellulosic Materials and Nano Alominum Oxide in Manufacture of Brake Lining

In the present study، development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. Variable factors were the type of lignocellulosic materials (Jute، bagass and rice husk) and the size of aluminum particles (nano and micron). These newly formulated brake pads have been tested under the grey cast iron disc. Friction coefficient and wear rate and thermal expansion were examined. Results showed that brake pads made from jute fibers and nano alumina have the best shear strength properties and the highest shear strength was obtained by using of rice husk and micro alumina. Also the best friction coefficient was about the manufactured linings by bagass fhbers and nano alumina and the lowest wear rate was observed in the linings made of rice husk and micro alumina. Results showed that brake pads made from Lignocellulosic fibers have desirable properties in comparison with standard values. Therefore using of this material in manufacture of brake lining is possible and properties of the linings made of nanoaumina were improved.
