The number of engineering application in industry demands need light weight, good mechanical properties of material such as aerospace, automotive industry. Day by day selection of material with good mechanical property is the pin point for material selection, hence because it’s high stiffness CNT are considered for widely used reinforcement of material in metal matrix Composite. These work summaries the research work carried out in the field of carbon nanotube (CNT) metal reinforcement for composite material. However, CNT - reinforced CuZn30 (Brass) has received the least attention, so that this work also explore more data regarding CNT reinforced CuZn30 (Brass). The main aim of this project is to fabricate and study the mechanical as well as Tribological properties of CuZn30 - MWCNT composite. Multiwall carbon nanotubes (MWCNTs) reinforced CuZn30 Nano composites are fabricated by mechanical alloying and powder metallurgy technique. The reinforcement material MWCNTs are blended in three weight fractions (0.33%, 0.66%, and 0.99%) with the matrix material CuZn30 (Cu - 70%, Zn - 30%) and blended through mechanical alloying u sing a high energy planetary ball mill. Specimens of CuZn30 and CuZn30 - MWCNT composites are fabricated through powder metallurgy technique. After fabrication of CuZn30 - MWCNT it is sintered to arranged CNT in unidirectional. The microstructure, density, har dness, porosity, and wear properties of CuZn30 and CuZn30 - MWCNT Nano composites are characterized and compared with pure CuZn30 composite for the effect of addition of MWCNT.
