The analysis of variance (ANOVA) was applied to identify the effect of mixture ratio of SGF and PTFE reinforced PC composites for the permittivity and dielectric strength and tensile strength.By regression analysis, a mathematical predictive model ofthe permittivity and dielectric strength and tensile strength were developed in terms of the mixture ratio setting. The combining BPNN/GA optimization method can be obtained for the appropriate combinations of the optimal mixture ratio setting. In addition, the result of BPNN integrating GA was also predictive with BPNN approach. The results show that the optimal mixture ratio setting gives appropriate combinations with a PC of 0.72, a SGF of 0.20, and a PTFE of 0.08 by RSM approach. Additionally, BPNN/GA approaches are gives appropriate combinations with a PC of 0.73, a SGF of 0.20, and a PTFE of 0.07. By verification results show the proposed algorithm of GA approach has better prediction result than the RSM method. Yung-Kuang Yang 楊永光 2011 學位論文 ; thesis 88 zh-TW |
