Compression molding is widely used process for the industrial forming of fiber reinforced plastic articles. Its applications are of an extreme variety and the products range from large parts, such as used in the automotive industry to much smaller objects. In this paper, distribution of fiber orientation by the image processing method for rib type compression molded products of each fiber content is measured. And the effects of fiber content, product size on the orientation state are discussed.

This study aims to systematically research the various phenomena which arise from compression molding of fiber reinforced plastic composites. Long fiber reinforced plastic composites are rib type compression molded in order to measure the orientation in products, and the specimens are photographed with soft X-ray. The intensity of the photograph is applied by an image scanner, and the fiber orientation distribution of products is measured by using an image processing technique.
