Abstract: The Raman spectra of the carbon fiber sheet, carbon fiber sheet/epoxy resin sheet, carbon fiber sheet/epoxy resin sheet/carbon fiber sheet were carried out. And the Raman spectra of carbon fiber sheet under high temperature and uniaxial stress were also carried out to explore the residual stress evolution. The testing results show that the Raman D mode and G mode are sensitive to the epoxy resin sheet solidification, temperature and uniaxial stress, and can be used to explore the interfacial residual stress between carbon fiber sheet and epoxy resin sheet. The Raman technology has the potential in the future nondestructive testing field.
