Abstract: Resin mat rix composites are of ten used with metallic materials. The unidirectional laminate was fabricated by a filament wound method. The Fiber Bragg Grating ( FBG) was embedded between filament wound compositelamination and aluminum plate to monitor the interface performance of two different materials during the cureprocess , and it was compared with the result s f rom the internal composite monitoring. The result s show that thetemperature evolution of the composite cure process was monitored exactly by the Fiber Bragg Grating ; it was foundthat there is an obvious difference between the st rains before and af ter the curing process. The Fiber Bragg Gratingprovides a tool to monitor the cure process between two different materials and a new method to analyze the interfaceperformance.
