This study explores the effect of interfacial properties on damage evolution and damage mechanisms in model glass fiber reinforced epoxy matrix composites. The composite properties were varied by changing the interfacial bond between the fiber and the matrix. Double‐edge‐notched specimens were tested in tension and evaluated using thermoelastic stress analysis (TSA) to observe damage initiation and evolution, and to identify the operative damage mechanism. Changing the interface properties was found to change the operative damage mechanism. This study conclusively demonstrates that the damage mechanism in composites can be controlled by judicious changes in the interface properties. POLYM.
