Abstract:

All apparatus for testing adhesive shear strength having a cylindrical adhesive bond between test specimens which is subjected to pure shear. The test specimens are two cylindrical rods. One rod has a bore and counterbore reamed into one end along its longitudinal axis. The other rod has a diameter essentially equal to the diameter of the bore. The adhesive to be tested is placed within the bore and counterbore and the smaller diameter rod is inserted into and seated at the base of the bore. The adhesive fills the space between the smaller rod and the counterbore, creating a uniform, cylindrical layer of adhesive between the exterior surface of the smaller rod and the inner surface of the counterbore. When the adhesive cures, the assembly is subjected to a tensile load along its longitudinal axis, tending to pull the inserted rod from the bore and subjecting the cylindrical adhesive bond to a pure shear load.
