Advanced Composite Performance: Material Behavior and Life Cycle Prediction for Rotating Machines

Abstract : The Virginia Tech life prediction methodology is applied to composite materials to determine a fundamental understanding of material behavior and life cycle issues (e.g. fatigue damage, creep, creep rupture). Specific areas addressed in this activity include: (1) establishing the likely damage and failure modes for rotating machines; (2) constructing micromechanical models of the material failure modes; (3) constructing a methodology for the life analysis of composite rotors operating under high temperature and loading.
