The ultimate and fatigue strengths of the fiber/matrix interfacial bond of four fiber/matrix combinations (fiber: carbon, polyaramid; matrix: polysulfone, polycar bonate) have been quantitatively investigated in a dry 37°C environment using the TRI microbond single fiber pull-out test method. Fatigue testing was conducted at 1 Hz using a sinusoidally varying applied load. Each sample type exhibited a linear relationship be tween peak applied interfacial shear stress and the logarithm of fatigue life. Interfacial bond fatigue behavior is apparently significantly influenced by both matrix viscoelastic be havior and fiber/matrix interfacial bond ultimate strength.
