CompositeNet Glossary of Terms
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.
CONCRETE REPAIR TERMINOLOGY
crazing—the development of craze cracks; the pattern of craze cracks existing in a surface. (See also checking and craze cracks.)
debond—a separation of bonded surfaces.
- checking—shallow, closely spaced cracks that form an irregular pattern.
- craze cracks—fine random cracks or fissures in a surface.
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.
