During this thesis, the design and development of novel multifunctional MAX reinforced polymer (MRPs) matrix composites was studied. MRPs were fabricated with a certain volumetric ratio of polymers and MAX phases. In Chapter II, synthesis and tribological behavior of PEEK-Ti3SiC2 composites have been reported. A decrease in friction coefficient is observed when 10 volumetric % of Ti3SiC2 was added in the PEEK matrix. Also, the wear rate of the composites decreases by 27 times when 5 volumetric % of Ti3SiC2 was added. In Chapter III, novel self-lubricating Teflon-Ti3SiC2 and Nylon-Ti3SiC2 composites are reported. During self-mating, Ti3SiC2-Teflon composites showed better performance than Ti3SiC2-Nylon composites. In the case of friction coefficient, a marginal decreased is observed for Teflon composites but for Nylon-Ti3SiC2 composites, an increase in friction coefficient is observed as the percent content of Ti3SiC2 was increased. However, the wear rate decreased to (5Â±3) x 10-5 mm3/N.m and (1Â±1.5) x 10-5 mm3/N.m in Teflon-5%312Si and Teflon-10%312Si, respectively, and thereafter retained a similar value of (1.6Â±1.6) x 10-5 in Teflon-30%312Si. We have observed a decrease in wear rate for Nylon-Ti3SiC2 composites but it is very marginal decrease. In Chapter IV of this thesis, the scope of future studies are discussed.
