Intersecting Rib Geometry for Warping Suppression in Composite Moldings

The patent applies local quality by forming rib portions only in specific regions where warping is most likely to occur, rather than uniformly across the entire surface. The rib portions are strategically positioned based on the warping tendency map, which identifies high-risk areas. This localized approach provides effective warping suppression while minimizing the additional mass compared to uniform rib formation across the entire surface.

The patent implements partial action by forming rib portions only in certain areas where warping suppression is most needed, rather than applying the same treatment uniformly across the entire molded body surface. The rib portions are positioned according to warping tendency analysis, providing sufficient stabilization in critical regions while avoiding unnecessary material addition in areas where warping is less likely to occur.

The patent reduces manufacturing cost by applying rib portions only in specific high-warping-risk regions identified through warping tendency analysis, rather than uniformly across the entire surface. This localized approach minimizes the amount of additional material and processing required, thereby reducing manufacturing costs while maintaining effective warping suppression in critical areas.

The patent implements cost-effective warping suppression by applying rib portions only partially in regions where they are most needed, rather than uniformly across the entire molded body. This partial application reduces material consumption and manufacturing complexity, leading to lower production costs while achieving sufficient warping control in high-risk areas.

The patent applies segmentation by dividing the fiber reinforcement into two components: long fibers (several mm to several tens mm) that provide overall strength, and short fibers (1 mm or less) concentrated in rib portions that provide local stabilization. This segmented fiber length strategy allows the main body to maintain high strength with long fibers while the rib portions with short fibers effectively suppress warping during demolding through localized reinforcement.

The patent uses local quality by concentrating short fibers specifically in the rib portions where warping suppression is needed, rather than uniformly distributing all short fibers throughout the entire molded body. This localized fiber distribution optimizes the fiber length composition in critical regions, providing effective warping resistance at the rib portions while maintaining overall structural strength through the long fiber network.
