Bottom-up Composite Materials Design for Multifunctionality
Nature has long demonstrated that hierarchical material hybridization—even at the atomic level—can lead to optimized performance with minimal mass. Drawing inspiration from these principles, Dr. Ajit K. Roy presents a compelling vision for the future of composites materials design: one that begins from the atomic scale up.
In this lecture, Dr. Roy explores how bottom-up materials design unlocks unprecedented potential for multifunctional composites, enabling simultaneous optimization of:
- Mechanical strength
- Thermal conductivity
- Electrical and dielectric performance
- Lightweight architecture
Key Highlights:
- Atomic-scale hybridization as the ultimate goal in materials morphology optimization
- Integration of multiscale modeling techniques such as:
- Density Functional Theory (DFT)
- Atomistic Molecular Dynamics (MD)
- Tight-binding DFT
- Monte Carlo & Boltzmann transport models
- Molecular Mechanics (MM)
- Leveraging these tools to connect atomic-level behavior with macroscale performance across time and spatial domains
Through selected examples, the talk illustrates how atomic-scale design can lead to concurrent multifunctionality in composite systems—opening doors to next-generation applications in aerospace, defense, electronics, and energy systems.
This presentation makes a powerful case for hybrid materials design as both a science and an engineering strategy, blending computational rigor with physical insights across scales.
