107329 - Architected Cellular Materials for Structure Design in Aerospace Applications 

Designing high-performance, lightweight materials has always been an ongoing challenge in aerospace structural design. Sandwich panel composites with lattice cores are one of the widely used structures in various aerospace applications. However, most of the existing used lattices (e.g., honeycomb) structures have a limited material property spectrum, thus limiting the achievable functionalities. This paper proposes implicitly represented microstructures for functional part design in aerospace applications. Unlike lattice materials, implicitly represented materials can have more combined functionalities in the same design. They also can be controlled by the minimum number of parameters and are highly scalable. We present a novel design paradigm specifically altered for aerospace applications. A multi-scale modeling framework uses implicitly represented architected materials with high-performance, multifunctional, and lightweight characteristics. As a demonstration of the novelty and capabilities of this framework, two structures with different applications are designed using the presented paradigm. The first case study is to model an airplane wing leading edge with embedded anti-ice functionality. The second case study is a lightweight, high-performance heat exchanger optimized for maximizing the specific surface area of the porous material.
