Nature-inspired microvascular networks have profound potential to offer a wide range of multi-functionality to host materials by enabling internal fluid/mass transport. Fiber-reinforced polymer composites exhibit superior structural performance (e.g., high specific strength/stiffness) whereby internal vasculature provides additional functionality including self-healing, thermal regulation, electromagnetic modulation, etc. We focus on the thermal management capability of microvascular fiber-composites which has a broad range of applications including electric vehicle battery packaging, space re-entry and hypersonic aircraft, and heat exchangers for microelectronics.
We are interested in developing a comprehensive design framework for microvascular composites to improve their thermal performance. This design framework includes Topology Optimization (TO), Hybrid Topology Optimization (HyTopS), Shape Optimization (SO), and Size Optimization.
