Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing

The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0?/90? and ?45?. The main tensile properties were determined as a basis for subsequent dynamic tests, in which permanent dynamic strength, crack growth, and crack growth rate in the material due to the action of fatigue load were assessed. Comparisons were made regarding the structure of the tested specimens. Samples were obtained from...
