==Advantages and disadvantages of composite construction==

===Advantages===
The main advantage of composite bows over [[self bow]]s (made from a single piece of wood) is their combination of smaller size with high power. They are therefore more convenient than self bows when the archer is mobile, as from horseback, or from a chariot. Almost all composite bows are also [[recurve bow]]s as the shape curves away from the archer; this design gives higher draw-weight in the early stages of the archer's draw, storing somewhat more total energy for a given final draw-weight. It would be possible to make a wooden bow that has the same shape, length, and draw-weight as a traditional composite bow, but it could not store the energy, and would break before full draw.<ref name=TBB/>

For most practical non-mounted archery purposes, composite construction offers no advantage; "the initial velocity is about the same for all types of bow... within certain limits, the design parameters... appear to be less important than is often claimed." However, they are superior for horsemen and in the specialized art of flight archery: "A combination of many technical factors made the composite flight bow better for flight shooting."<ref name=Kooi>{{cite journal |url=http://www.bio.vu.nl/thb/users/kooi/kobe97.pdf |title=An Approach to the Study of Ancient Archery using Mathematical Modelling. |first1=B.W. |last1=Kooi |first2=C.A. |last2=Bergman |journal=Antiquity |volume=71:(271) |pages=124–134 |year=1997 |issue=271 |doi=10.1017/S0003598X00084611 |s2cid=36104959 |access-date=28 October 2007 |archive-url=https://web.archive.org/web/20061121144334/http://www.bio.vu.nl/thb/users/kooi/kobe97.pdf |archive-date=21 November 2006 |url-status=dead }}</ref> The higher arrow velocity is only for well-designed composite bows of high draw-weight. At the weights more usual for modern amateurs, the greater density of horn and sinew compared with wood usually cancels any advantage.<ref name="ottoman-turkish-bows.com"/>

===Disadvantages===
Constructing composite bows requires much more time and a greater variety of materials than self bows, and the [[animal glue]] used can lose strength in humid conditions; the 6th-century [[Byzantine Empire|Byzantine]] military manual, the ''[[Strategikon of Maurice|Strategikon]]'', advised the cavalry of the [[Byzantine army]], many of whom were armed with composite bows, to keep their bows in leather cases to keep them dry. Karpowicz suggests that crafting a composite bow may take a week's work, excluding drying time (months) and gathering materials, while a self bow can be made in a day and dried in a week.<ref name="ottoman-turkish-bows.com"/> Peoples living in humid or rainy regions historically have favoured self bows, while those living in temperate, dry, or arid regions have favoured composite bows. 

[[Medieval European History|Medieval Europeans]] favoured [[self bow]]s as hand bows, but they made composite [[Crossbow#Construction|prods]] for crossbows. The prods were usually well protected from rain and humidity, which are prevalent in parts of Europe. Ancient Mediterranean civilizations, influenced by Eastern Archery, preferred composite recurve bows, and the Romans manufactured and used them as far north as [[Roman Britain|Britannia]].<ref>Coulston, J.C.

The civilizations of [[India]] used both self bows and composite bows. The Mughals were especially known for their composite bows due to their Turko-Mongol roots. Waterproofing and proper storage of composite bows were essential due to India's extremely wet and humid subtropical climate and plentiful rainfall today (which averages {{convert|38|-|58|in|mm|abbr=in|order=flip|disp=or}} in most of the country, and exceeds well over {{convert|100|in|mm|abbr=in|order=flip|disp=or}} per year in the wettest areas due to monsoons).<ref name="eldoradoweather.com">{{Cite web|url=https://www.eldoradoweather.com/climate/world-maps/world-annual-precip-map.html|title=World Average Yearly Annual Precipitation|access-date=1 April 2019|archive-date=1 April 2019|archive-url=https://web.archive.org/web/20190401150157/https://www.eldoradoweather.com/climate/world-maps/world-annual-precip-map.html|url-status=live}}</ref>

The civilizations of [[China]] also used a combination of self bows, composite recurve bows, and laminated reflex bows. Self bows and laminated bows were preferred in southern China in earlier periods of history due to the region's extremely wet, humid, and rainy subtropical climate. The average rainfall in southern China exceeds {{convert|38|in|mm|abbr=in|order=flip}}, averaging {{convert|58|-|97|in|mm|abbr=in|order=flip}} in many areas today.<ref name="eldoradoweather.com"/>
