The purpose of this thesis is to explore the influence of parameters of fire resistance of composite materials with the Taguchi method by using the least number of experiment and cost. The orthogonal array of Taguchi method is used to organize the experiment and the limiting oxygen index (L.O.I.)、the smoke density 、the mechanical properties. of fire resistance of composite material PEIPET which is obtained according to the test standard ASTM D2863,ASTM E662,ASTM D3029-84. The test data are used to do the controllable factors (parameters) of signal to noise ratio (SIN) analysis in order understand the influence of controllable factors of the materials. The contribution rate of each controllable factors is estimated by analysis of variance (ANOVA). The optimal factors are chosen and verified by experiment to the best.
