Definition
A localized penetration of a composite structure caused by a sharp or pointed object striking the surface, producing a hole or piercing damage that breaks through one or more layers of the material.
Plain English
A small hole or piercing made when something sharp pokes through the surface of a part.
Context Anchor
Seen when discussing damage to composite aircraft parts, especially during preflight or after an impact with a tool, rock, bird, or other sharp object.
Derivation
From the Latin punctura, meaning 'a pricking,' from pungere, 'to prick or pierce.' The same root gives us 'point' and 'puncture wound.' This helps because it captures the key idea: damage caused by a sharp point, not a broad impact.
Why Pilots Care
Composite materials can hide serious internal damage behind a small visible puncture. Even a minor-looking hole may indicate broken fibers and weakened structure underneath, so any puncture should be inspected before flight.
Intuition Check
Do not think of puncture only as tire damage. In this context, it can mean a hole or pierced area in any aircraft structure, including composite skin.
Example Sentence 1
During preflight, the pilot found a small puncture in the composite wingtip and grounded the aircraft until a mechanic could inspect it.
Example Sentence 2
Unlike aluminum, the composite skin showed no dent after the hail strike, yet a puncture had occurred beneath the surface.
