Laser Raman Spectroscopy (LRS) is a powerful technique for studying the structure of materials and for measuring strain at a micron level resolution. LRS was utilized for microstrain analysis in carbon-carbon (CC) composites and for characterization. First order Raman spectra corresponding to carbon fibers and carbon matrices were found to be clearly distinguishable. The graphitic nature of the fiber and matrix material was quantified and compared. Strain measurements were taken in both the fiber and the matrix under bending conditions and thermal exposure conditions. Distribution of the strain along fibers in carbon prepreg was also evaluated. In summary, LRS is an innovative approach for evaluating the strain distribution and degree of graphitization in CC composites.
