Porous Functionally Graded Materials (pFGM)
Our research is dedicated to developing cutting-edge tools for designing and manufacturing 3D porous functionally graded materials (pFGMs) with tailored mechanical properties, particularly in energy absorption profiles. These advancements are crucial for a wide range of industrial applications, including aerospace, construction, transportation, and bioengineering. The complex nature of pFGMs has historically limited researchers to empirical trial-and-error methods due to the absence of comprehensive design models.
Key Research Areas:
In-Silico Modelling for Optimized Energy Absorption:
We are focused on creating efficient numerical models for pFGMs by utilizing finite element modeling (FEM) coupled with AI-based search algorithms. This approach enables the design of 3D architectures and materials optimized for energy absorption, offering precise control over the mechanical properties of porous structures.Innovative Digital Manufacturing Techniques:
Our research incorporates advanced 3D printing technologies using dispersed materials, such as emulsions or foams. We control droplet and bubble sizes on demand by employing reconfigurable microfluidic printing heads. The integration of 3D printing with microfluidics allows for unprecedented control over local material properties, including pore size, pore connectivity, and material composition.Advanced Material Characterization:
We utilize state-of-the-art technologies for material characterization, including mechanical testing paired with high-resolution micro-computed tomography. This allows us to thoroughly analyze and validate the properties and performance of the manufactured pFGMs.
