Abstract: | <p>Multilayer polymer decorative films are showing a growing presence in the automotive industry, substituting conventional paint applications while maintaining similar aesthetic appeal. However for certain film constructions that have distinct layer properties, the polymer film laminates have shown to form wrinkles on application of heat during thermoforming. In this study, attempts were made to identify the factors influencing wrinkling and to predict the variation in the wrinkle parameters under changing forming conditions using existing theoretical models. A new modified thermoforming technique is proposed for producing thermoformed parts without wrinkles and thereby achieving a <em>Class A</em> finished surface.</p> |
