Participant Support Cost for GOALI: Investigation of Cyclic Failure in Aluminosilicate Nanocomposites SP0054183

Project: Research project

Description

Aluminosilicate material composites are a new breed of multifunctional inorganic polymer composites with advanced properties such as low density, high strength, high thermal stability, and low shrinkage. Potential applications include porous membranes for renewable energy, biomaterials for bone grafting, insulation system parts, and alternative cementitious materials. However, the resistance to cyclic failure of aluminosilicate nanocomposites is poorly known. The lack of knowledge reduces the widespread integration of aluminosilicate nanohybrids in science and industry despite their many advantages. Our research goal is to gain a fundamental understanding of fatigue processes at the nano- and micrometer lengthscales in nanoreinforced aluminosilicate composites. The proposed research is organized around three major objectives: (i) Generate fatigue crack growth curves for homogeneous aluminosilicate materials using novel depth-sensing experiments, (ii) Investigate the influence of pore size on the fatigue behavior for porous aluminosilicates, and (iii) Investigate microstructure-fatigue relationship in nano-reinforced aluminosilicate composites
