Correlation between crack propagation rate and cure process of epoxy resins
- Fracture mechanics approaches are increasingly applied for the characterization of epoxy resin and adhesive mechanical properties. Therefore, the fracture toughness and crack resistance under static load ISO 13586 [1] are often regarded as state of the art to analyse material improvements. However, experimental investigations on fatigue behaviour, thus the crack propagation according to ISO 15850 [2], seem to be much more sensitive to characterize the materials for in service loading conditions. Firstly, an efficient testing concept was developed at BAM. In this framework, the geometry for a modified single edge notched tensile specimen (SET) was developed in order to assure appropriate resolution in measuring the crack length via a CCD-camera [3]. In the next step, the influence of the cure temperature on the fracture-mechanical properties was investigated.
