ABSTRACT:
A system for testing the properties of a material used in sealing gaps between aircraft panels. The system includes a first device having a pair of interior plates positionable on opposite sides of a first specimen, a pair of intermediate plates located on the sides of the interior plates remote from the first specimen, a pair of exterior plates located on the sides of the intermediate plates remote from the specimen, drive shafts coupled to the exterior plates, a first mechanism connected to the drive shafts for imparting motion thereto, and a first electrical device connected to the interior plates for testing the properties of the first specimen during the operation of the first mechanism. The system also includes a second device having a pair of primary plates with interior portions spaced from each other, a pair of secondary plates secured to the interior portions of the primary plates on opposite sides of a second specimen, the second specimen being formed in a specimen-receiving space located entirely over only the interior portion of one of the primary plates, a second mechanism connected to the primary plates for imparting motion to at least one of the primary plates and its secured secondary plate, and a second electrical device connected to the secondary plates for testing the properties of the second specimen during the operation of the second mechanism. Also disclosed is a method of testing such specimen.
