Notes:
The mechanical properties of composite laminates play a key role in the success ofcomposite reinforcement method, but various investigations suggest that the stiffness of epoxybasedcomposites is sensitive to the variation of moisture ratio and temperature of the workingenvironment. The aim in this research is to characterize the effect of hygrothermal aged compositepatch on the strength of repaired cracks, under mixed mode I/II conditions. For this purpose areinforced sheet, i.e. a crack fastener hole specimen is examined by using a finite elementsimulation. The crack tip parameters and fracture characteristics of repaired cracks are determinedas a function of the total amount of moisture inside the composite patch. The results of this studyshow that the performance of composite reinforcement technique depends on the amount of waterabsorption within the bonded patches
