Compo is a term often used to refer to a composite material, which is made from two or more different substances to create a new material with enhanced properties. These materials are commonly used in various industries, including construction, automotive, and aerospace, due to their strength, lightweight nature, and resistance to corrosion. In the context of sports, "Compo" can also refer to a composite bat, which combines materials like wood and fiberglass to improve performance. These bats are popular in baseball and softball, as they offer better durability and hitting power compared to traditional wooden bats.
