A composite bow is a traditional bow made from horn, wood, and sinew laminated together, a form of laminated bow. The horn is on the belly, facing the archer, and sinew on the outer side of a wooden core. When the bow is drawn, the sinew (stretched on the outside) and horn (compressed on the inside) store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood "self" bows, with similar draw-length and therefore a similar amount of energy delivered to the arrow from a much shorter bow. However, making a composite bow requires more varieties of material than a self bow, its construction takes much more time, and the finished bow is more sensitive to moisture.
Archaeological finds and art indicate composite bows have existed since the second millennium BCE, but their history is not well recorded, being developed by cultures without a written tradition. They originated among Asiatic pastoralists who used them as daily necessities, classically for mounted archery, although they can also be used on foot. Such bows spread among the military (and hunters) of civilizations that came into contact with nomad tribes; composite bows have been used across Asia from Korea to the Atlantic coasts of Europe and North Africa, and southwards in the Arabian Peninsula and in India. The use of horn in a bow was even remarked on in Homer's epic The Odyssey, believed to have been written in the 8th century BCE.
The details of manufacture varied between the various cultures that used them. Initially, the tips of the limbs were made to bend when the bow was drawn. Later, the tips were stiffened with bone or antler laths; post-classical bows usually have stiff tips, known as siyahs, which are made as an integral part of the wooden core of the bow.
Like other bows, they lost importance with the introduction and increasing accuracy of guns. In some areas, composite bows were still used and were further developed for leisure purposes. Early modern Turkish bows were specialized for flight archery (shooting for distance). Composite bows are still made and used in Korea and in China, and the tradition has been revived elsewhere. Modern replicas are available, often made with fiberglass bellies and backs with a natural or man-made core.
