means Protective armor built from multiple layered materials (like ceramics, metals, and composites) rather than a single solid substance, so each layer defeats threats the others can't.

from The word 'composite' traces back to Latin 'componere' — 'com-' (together) plus 'ponere' (to put or place) — literally 'put together.' The military application took off in the mid-20th century, when engineers discovered that sandwiching hard ceramic plates between metal and fiber layers defeated shaped-charge warheads far better than a single slab of steel ever could — a direct response to the arms race between armor and anti-tank weapons like HEAT rounds.
