Abstract : A test fixture for detecting delamination of laminated structures, comprising a contact head with a first cavity in one flat surface thereof with the shank of a dial indicator inserted into a second co-axial cavity in the opposite face of said contact head. The contact point of said indicator is located near the plane of the rim of said first cavity. The first cavity is evacuated so that as the fixture moves over a laminated surface, improperly bonded laminates will be urged into the first cavity under the influence of the vacuum therein and produce a reading on the dial gauge.
