An experimental study of the thermal performance characteristics of TMA glass transition
temperature is developed. Three kinds of nanopowder, namely, alumina, silica and carbon
black, are selected and mixed with reactive diluent to prepare a novel epoxy
nanocomposite. By analysis of variance, it is found that the control factors are significant
factors to qualify the glass transition temperature of the nanocomposite. In the study, the
glass transition temperature is effectively optimized by using Taguchi method. As a result,
the optimum composition is to adding 2 wt.% of Al2O3, 2 wt.% of SiO2, and 2 wt.% of
carbon black of the nanocomposite. The multiple regression equation can be established
from the experiment to determine the weighted coefficient of control factors and quality
characteristics. The error between the experimental value and the prediction value, which
is calculated by the regression equation, is only 0.06%. It confirms the reliability of this
study.
