This study aimed to use D-optimal combined design, and partial least squares discriminate analysis (PLS-DA) to investigate the mechanical properties, and chemical compatibilities of improved epoxy nanocomposites by nano TiO2/Al2O3. Experimental design of adhesion, and wedge bend properties led the results into the optimum values of TiO2= 0.66%, Al2O3= 1.33%, dispersant= 0.000017%. The variable importance […]
