An innovative approach has been developed to fabricate composite parts with complicated geometry. The part is first divided into several simple substructures and each substructure is produced by an optimal process. These preformed substructures are then assembled on a specially designed tool and transferred into a mold cavity for resin impregnation by structural reaction injection molding (SRIM). A composite link is used as an example in this study. The mold filling pattern is simulated using a 3‐D computer model. The simulated results compared well with the experimental results when race tracking and fiber impingement effects were considered in the model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
