Composite structures have been developed for use in aerospace, automotive, sports and marine industries since the early 1940s. Compared to conventional metallic structures, high-performance composite structures provide benefits such as decreased weight and energy consumption. An ISO subcommittee on Industrial Data has developed and implemented a standard for sharing the manufacturing information for these complex composite structures. This standard is essential for improving the design, analysis, and manufacturing productivity of composite structures, and for enabling the long-term data retention necessary to support the composite structures throughout the lifetime of the products that use them. This paper will describe the development and content of the ISO 10303 data models for composite structural shape and composition. The paper will also report the status of ongoing implementation efforts, including efforts to use this standard to support long-term data retention. The varied usage scenarios have motivated several areas of improvement such as full 3D representation and the efficient, cost-effective visualization of composite structural parts. Issues and their proposed solutions, along with their impacts on the design, analysis, manufacturing, and long-term support of composite structures will also be discussed.
