Abstract

Optimizing the curing temperature to reducing the process costs may influence the properties of the material and bring quality assurance aspects. To solving the problem, real-time strain monitoring of the curing process has become more and more important and urgent. Fiber Bragg grating sensors were successfully used in this work to monitoring the residual strain building-up and the gelling phenomena of an RTM epoxy resin. The results shows chemical shrinkage strain during isothermal curing is bigger for higher curing temperature, but the average linear shrinkage ratio during cooling is smaller.
