BVID

Barely Visible Impact Damage 

BVIDBarely Visible Impact Damage is the name given to damage in a composite material (for example CFRP) caused by a low-velocity impact from objects during maintenance or operation. Such objects can be dropped tools or runway debris. Low-velocity impacts cause only minor damage to the surface of the composite, which is generally not readily detectable by visual inspection, hence the term BVID. However, they can cause structurally significant damage internally within laminate composites, such as delamination, matrix cracking, fibre fracture and fibre pullout.
