Optimizing synthesis parameters of short carbon fiber reinforced polysulfonamide composites by using response surface methodology

Abstract In this paper, the synthesis parameters of short carbon fiber reinforced polysulfonamide composites (SCF/PSA composites) were optimized. Box-Behnken design was applied to conduct the experiments. The influences of temperature, time and composition on mechanical strength of SCF/PSA composites were studied by response surface methodology and grey relational analysis. The results show the composition was the most influential factor and the optimal process parameters are as follows: 372.88 °C (temperature), 29.17 min (time), and 40 wt% (composition). The fracture surface morphology of compression and tension sections of the obtained composites was analyzed by Tungsten filament scanning electron microscopy (TF-SEM).
