Abstract

The greatest concern of an engineer posed from the use of composite materials is structural integrity both during fabrication and in service. The presented experimental investigation, supported initially by numerical analysis, addresses the capability of using two technologies of sensing during the curing cycle of Composite Patch Repair (CPR), so as to guarantee achievement of optimal cure levels. These sensors are further subject to post curing for structural integrity. The presented series of preliminary experiments have exhibited identification and completion of cure simultaneously from both sensor systems. In general, curing is completed prior to the end of the temperature treatment, a fact that could potentially lead to important cost reductions.
