delamination

This term is primarily used in technical, engineering, and materials science contexts. It describes a specific type of structural failure where layers that were intended to be bonded together separate. While it can describe a natural process of decay, it is most frequently used to denote a defect or a critical failure in composite materials, such as carbon fiber or plywood.

Because it refers to a process or a state of failure, it is typically treated as an uncountable noun. It describes the phenomenon itself rather than individual instances of peeling, which would be referred to as "layers" or "flakes."
