摘要：
Products molded from fiber reinforced material are subject to several problems during the manufacturing process such as sink marks, warpage and short shots. In an earlier work, the authors used finite element analysis to analyze the in-mold flow behavior of sheet molding compound (SMC) during the compression molding process. The analytical results were then verified through experimentation. This report first proposes an explanation for the mechanism generating sink marks in a ribbed product having a simple shape. Based on that understanding of the mechanism, a method for minimizing sink marks has been devised and confirmed through experimentation to be effective. The results of the present work are now being used to establish a molding concept for a one-piece outer panel. © 1990.
