The origin and damage of curing residual stress were firstly investigated briefly in this paper.And then Fiber Bragg Grating (FBG) sensors with different central wavelength were used to test the temperature sensitivity and the strain sensitivity. At last, the naked and encapsulated FBG sensors were layed parallelling into prepreg to monitor the whole curing process, and the results clearly showed the situation change of strain, the appearance of gel point and glass transition temperature.
