OSTI ID:5954195
Purpose is to develop statistical and micromechanical models of time-dependent failure in fiber composites in order to forecast long-term reliability. Three problems are being studied: micromechanics of stress transfer at fiber fracture sites; modeling time-dependent effects in both fiber and matrix under one unified power-law framework; and creep-rupture of single Kevlar 49 fibers at high temperatures up to 200/sup 0/C.
