Method for Engineered Topology of Composite Structures
This invention is a method for engineering composite structures with well-defined topological characteristics. It allows the resulting composite to be intentionally designed to exhibit either trivial or non-trivial topology, rather than leaving that outcome to the natural result of combining materials. In practical terms, the method gives researchers...
