abstract = "Chemical cure shrinkage of polymer matrix is a significant source of residual strain formation in composite products during curing. In this paper, fiber Bragg grating (FBG) sensors were used to monitor the free strain development caused by chemical shrinkage and compared with results of differential scanning calorimetry and rheological analysis. The results showed that the gel point could be clearly identified by FBG sensors and compressive residual strain of around 800με was caused by isothermal curing reaction after gelation. The relationship between the chemical shrinkage ratio and conversion degree was found to be nonlinear.",
