Static and dynamic behavior of single‐edge notched glass fabric composites

Abstract This article describes the results of a series of tests conducted to support the development of a semiempirical model, for predicting the mechanical degradation of a satin weave glass fabric composite, with through‐thickness damage in the form of a crack‐like edge‐centered notch. Test specimens were subjected to loading in both static three‐point bending and dynamic mechanical thermal analysis (DMTA) tests. The effect of both notch length and displacement rate, on the static and that of notch length on the dynamic behavior of the materials tested, was evaluated and compared with respective predictions, as derived from the application of the residual property model. A satisfactory agreement between the experimental results and theoretical predictions was observed in all cases. Scanning electron microscopy was applied to observe the failure topographical characteristics of the DMTA specimens that were off‐plane loaded. POLYM.
