Abstract

In this paper, a methodology to build the required models for the performance comparison of materials that usually pass the standard inclined plane tracking and erosion tests, is presented. Samples made of silicone rubber and cycloaliphatic epoxy resin were evaluated to present the practical aspects of the proposed methodology. Factorial experiments, using the modified version of the inclined plane test method, were conducted to obtain the response variable. Generalized linear models provided the base for the proposed statistical models since the selected response variable was not normally distributed
