Research and development of a composite with transparent polypropene fiber Part I: a study of combining the Taguchi method with the analytic hierarchy process for masterbatch modification and toughening to enhance characteristics:

Polypropene (PP) has weak mechanical properties; relevant fibrous composite products are likely to bend under stress, becoming unavailable due to creases and folds. In order to maintain the product haze and tensile characteristic, the toughening property is enhanced greatly in this study. Firstly, the PP and enhanced rubber segment-styrene ethylene/butylene styrene (ERS-SEBS) are analyzed, and the two materials’ melting points and cracking points are confirmed. Three proportions of composite are made by single-screw mixing. The cost is reduced and the efficiency is confirmed by the Taguchi experiment. The single quality optimum combination is obtained by analysis of variance (ANOVA) and a factor response table. The optimum process parameters are designed according to the contribution degrees of quality weight and control parameters by using the analytic hierarchy process and ANOVA of the Taguchi method based on the reproducibility of the single quality optimum combination validation experiment.
