Definition
In aircraft construction, a material made by combining two or more distinct substances — typically reinforcing fibers (such as carbon, glass, or aramid) bonded together with a resin matrix — to produce a structure that is stronger, lighter, or more corrosion-resistant than either material alone.
Plain English
A material made by mixing strong fibers with a glue-like resin so the finished part is light but very strong. Many modern aircraft skins, control surfaces, and fairings are built from these materials instead of metal.
Context Anchor
Seen when describing aircraft structures such as wingtips, control surfaces, fairings, tail sections, and some complete airframes.
Derivation
From Latin compositus, meaning 'put together' or 'made up of parts.' That original meaning fits exactly: a composite part is literally several different materials put together to behave as one.
Why Pilots Care
Composite parts reduce aircraft weight, improve fuel efficiency, and resist corrosion, but they demand different inspection and repair methods than metal.
Intuition Check
Composite does not just mean any general mixture here. In aircraft structure, it means a built-up material whose combined parts act together as one structural material.
Example Sentence 1
The wingtips and tail fairings on this airplane are made of composite, which keeps the structure light without sacrificing strength.
Example Sentence 2
After the incident the mechanic checked the composite tail for any signs of damage.
