    Debonding es despegamiento.
    Crazing es la red de grietas superficiales que pueden formarse en la cerámica, etc.
    Void es un vacío. Como verbo, vaciar...

    Debonding: "Debonding is, however, a gradual process where slow growth of cracks occurs at the interface, and the characteristics of such growth including the coalescence of cracks is controlled by fracture-mechanics based parameters. Thus, fracture-based characterization of the interface will produce far more useful indicators of interfacial quality than the ultimate bond strength alone. This characterization may also be a better representation of interface damage and durability. The committee will also strive to develop fracture based bond tests." [http://www.rilem.org/tc_frp.php]

    Could you give us more context for "void"?

    Crazing: Fine cracks that may extend in a network on or under the surface of a plastic material.

    Debond: A deliberate separation of a bonded joint or interface, usually for repair or rework purposes.

    Void: A physical and mechanical discontinuity occurring within a material or part, which may be two-dimensional (e.g., disbonds, delaminations) or three-dimensional (e.g., vacuum-, air-, or gas-filled pockets). Porosity is an aggregation of micro-voids. Voids are essentially incapable of transmitting structural stresses or nonradiative energy fields.

    crazing—the development of craze cracks; the pattern of craze cracks existing in a surface. (See also checking and craze cracks.)

    • checking—shallow, closely spaced cracks that form an irregular pattern.
    • craze cracks—fine random cracks or fissures in a surface.
    debond—a separation of bonded surfaces.

    void
    cavity enclosed within an otherwise solid mass; may be intentionally or unintentionally formed and may be filled with air, water, or other gaseous or liquid material.
