Abstract
A computer-aided method for predicting the layup of fiber-reinforced prepreg resin material for compression molding into three-dimensional shapes depends on the area relationships of the final thickness of the molded shape to the initial thickness of the prepreg material. A graphic display is generated incorporating the initial thickness needed at each location on the prepreg material to provide the desired final thickness of the three-dimensional shape with controlled fiber distribution throughout the shape.
