| Abstract(E) | The application of bead-applied stiffening materials has been investigated to improve the panel stiffness of automotive outer panels. However, panel distortion caused by material shrinkage during the paint baking process is a critical issue. For vehicle implementation, it is necessary to determine appropriate bead dimensions (width and thickness) that do not induce distortion, but no reliable prediction method has been available. Through prototype testing of an actual vehicle door, it was found that incorporating material property changes during thermal curing significantly improves distortion prediction accuracy. |
