    Abstract

    A variety of experimental procedures for measuring composite fiber and void content has been evaluated, including resin removal by sulfuric acid digestion, water takeup, and quantitative microscopy. These techniques were applied to a series of graphite/epoxy laminates; a comparison of the results showed the more convenient resin-removal method to be sufficiently precise unless spatial distributions of the constituents are required, in which case microscopy is indicated.
