A composite bow is a bow made from disparate materials laminated together, usually applied under tension. Different materials are used in order to take advantage of the properties of each material. This article describes mainly the traditional Asiatic composite bow, which normally uses horn on the belly and sinew on the back of a wooden core. Sinew and horn will store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood bows, with similar draw-length and therefore a similar or greater amount of energy delivered to the arrow from a much shorter bow. Some Mongolian composite bows are known to have been able to produce a draw weight of nearly 160 lb (72.5 kg).
