This AFOSR URI addressed complex research problems of materials degradation and fatigue in aerospace structures in severe or extreme environments. A better understanding of materials degradation and flaw initiation dynamics was achieved through a multi-disciplinary research program encompassing chemistry, surface physics, materials science and mechanics, both experimental and theoretical. The Subprojects were as follows 1 Surface Induced Degradation of Fluorocarbon Lubricants 2 Molecular Tribology of Perfluoroether Lubricants 3 Fluids, Including Lubricants Under Extreme Conditions of High PressureHigh Temperature and Confinement 4 Surface Crack Propagation Under Combined Mechanical and High Pressure Fluid Loading and 5 Lubricant Assisted Fatigue Crack Growth in Ceramics.
