ABSTRACT:
An apparatus and method for gauging the amount of warpage in a composite panel is disclosed. The apparatus is used to measure the gaps between a cured composite panel (12) and the mold (10) upon which the panel was formed. The gaps are indicative of warpage in the panel. The apparatus includes inelastically deformable gauging strips (20) that are placed at selected locations on the mold. Also included is a mechanism (22,42,44) for accuraely positioning the panel adjacent to the mold after the strips are in place so that the panel contacts and partially crushes the strips. After the panel is removed, the thickness of each crushed gauging strip is measured at numerous points along its length. Variations in the thickness of the strip indicate the presence of gaps between the mold and panel, hence warpage in the panel.
