Abstract: A process for bonding elastomeric material to a metal part includes coating a heat curable adhesive on surfaces of the metal part to be bonded, placing the metal part in a mold, preheating a bottom plate and an upper transfer pot of a transfer molding machine to a predetermined cure temperature, loading a predetermined quantity of uncured elastomeric material into the transfer pot, clamping the mold containing the adhesive coated metal part to the bottom plate, and almost contemporaneously, pressing the uncured elastomeric material into the mold while maintaining heat and pressure in the mold for a time sufficient to vulcanize and thereby cure the elastomeric material simultaneously with the adhesive, whereby contacting surfaces of the metal part are strongly bonded to the vulcanized elastomeric material.

Abstract: This invention is a process for producing composite laminates containing interlaminar disbonds of controlled sizes, shapes, and positions within a composite structure. A composite layer is provided for later inclusion within a laminate. The surfaces of this composite layer are solvent cleaned and sandblasted, except in desired disbond areas, which are coated with a releasing surface. A template to mask the bond areas is employed to obtain disbond areas of controlled shapes and sizes. The resulting composite layer is then used in the subsequent manufacture of a laminate, whereby faulty adhesion in the laminate can be studied with prior knowledge of the size, shape, and location of the disbond areas.

Abstract: A process for preparing relatively thick composite laminate structures wherein thin layers of prepreg tapes are assembled, these thin layers are cut into strips that are partially cured, stacked into the desired thickness with uncured prepreg disposed between each layer of strips and the thus formed laminate finally cured and thereafter machined to the desired final dimensions.
