Virtual Manufacturing of Composite Structures for Ground Platforms, A DARPA Instant Foundry Adaptive Through Bits (iFAB) Program.

摘要

This effort focused specifically on the Liquid Composite Molding (LCM) class of processes as they are the ideal processes for medium to large scale components for ground platforms. UD-CCM has long history of fabricating composite structures for ground vehicles using these processes and the Figure below shows some examples of components fabricated over the years. The goal in this effort is to link composites design with process modeling, enabling the designer to evaluate manufacturability of the components in question. Historically, this has been a sequential process with component design and analysis followed by manufacturability assessment, usually through model fabrication runs or trial and error. The goal is to move to a concurrent approach, to significantly reduce the time from component design to functional prototype stage.
