We research and develop next-generation, structural composites that can sense, respond and adapt to their environment. Motivated by evolutionary advantage in living organisms, we create materials that achieve biomimetic, self-regulating (i.e., homeostatic) functions including thermal management and self-healing. Our latest thermal remending system can achieve 1,000+ self-repair cycles, which translates to century-scale healing, and greatly extends fiber-composites’ decades design life.
One way we mimic load-bearing biomaterials is by creating microvascular networks, akin to osteonic canals in bone, through a patented process known as Vaporization of Sacrificial Components (VaSC). These novel fiber-composites containing 3D microvasculature achieve multifunctional performance (e.g., thermal regulation, electromagnetic modulation) via substitution of circulated fluids within the vascular networks. By employing the latest in materials fabrication techniques, e.g., 3D weaving/printing, we can produce increasingly complex fiber-composite architectures.
Our latest research involves the integration of microelectronic sensors into advanced composite systems for coupling structural health monitoring (i.e., self-sensing) with self-regulating functions.
The group’s holistic vision for modern fiber-composites remains focused on bioinspired enhancements and synergistic functionality to imbue these engineered materials with nature’s evolutionary advantages.
