## Summary

In the field of aerospace engineering, polymer matrix composites have emerged as a highly sought-after material due to their exceptional lightweight and high strength properties. These composites are composed of advanced polymers, fibers, and fillers that possess a hierarchical structure at multiple length scales. This unique structure allows for the optimization of composite materials to meet specific design requirements. However, the complex nature of the design space, encompassing various constituent materials and architectural choices, presents a significant challenge for engineers. To address this challenge, a systematic and efficient approach known as the  has been proposed by researchers Satyajit Mojumder, Lei Tao, Ying Li, and Wing Kam Liu. This framework aims to identify the underlying mechanisms governing materials systems using limited available data and create a comprehensive composite knowledge database. Within this database, information on polymers at the nanoscale with , unidirectional structures at the microscale, and woven structures at mesoscale is compiled. These mechanisms can then be leveraged for part-scale composite design and analysis. The  not only facilitates a deeper understanding of  but also enables rapid evaluation of new materials system designs. By extending this approach to other material systems, designers will have access to essential tools for enhancing the efficiency and effectiveness of their design processes in
