چکیده
In this study, the optimum process parameters for manufacture of brake friction linings (BFLs) from palm kernel shells (PKS), periwinkle (PWS), and coconut shell (CNS) composites were established using signal–to–noise ratio based on Taguchi technique. The L9(34) orthogonal array was set up investigation performance metrics (coefficient friction, wear rate, hardness) synergized by multiple criteria evaluation. manufacturing considered molding pressure, temperature, curing time, heat treatment time. Consequently, optimized utilized production different BFL PKS/PWS/CNS mix. Finally, entropy TOPSIS techniques employed to isolate best composite comparative analysis. results show that are 29 MPa (molding pressure), 120 °C temperature), 6 min (curing time), 2 h (heat time). ANOVA Minitab 21.1.0.0 shows effects pressure time statistically significant at α = 0.05, with a total contribution 94.45%. entropy-TOPSIS analysis gave sample S2pkpc composition 12% PKS, 15% PWS, 18% CNS as composite. Compared asbestos BFL, an improvement in coefficient (45.7%), rate (66%), density (60.2%), oil water absorption (233%) (542.8%) respectively. live test Peugeot 301 confirms satisfactory However, increased observed vehicle speeds above 90 km/h.

The main objective of this study was production of ethanol from three lignocellulosic biomasses like sugarcane bagasse, rice straw and wheat straw by Sacchromyces cervisae. All the three substrates were ground to powder form (2 mm) and pretreated with 3%H2O2 + 2% NaOH followed by steaming at 130 °C for 60 min. These substrates were hydrolyzed by commercial cellulase enzyme. The whole fermentati...
