Abstract: The methods for determining the fiber volume fraction in carbon fabric reinforced composite laminateswere developed by using the processing and analyzing techniques of section images of laminates , which are sampledby the use of CCD camera and A/ D device. Special measuring step s were designed according to the principles of determining the fiber volume f raction , using the geomet rical method and threshold method. The captured images weremanipulated and analyzed using Photoshop sof tware. The result s are in agreement with the values offered by thecomposites maker. Therefore the methods are considered feasible.
