Bow (weapon)

A bow is a weapon that projects arrows powered by the elasticity of the bow. Essentially, it is a form of Spring . As the bow is drawn, energy is stored in the limbs of the bow and transformed into rapid motion when the string is released, with the string transferring this force to the arrow....

 to use materials on the back of the bow that are particularly strong in tension, and materials strong in compression on the belly; it is also easier to apply powered machinery to the manufacturing process so as to save time. For the amateur, lamination may make it possible to apply a strong backing to wood that would not otherwise make a good bow. A laminated backing may also save a great deal of time that would be spent following the grain of a natural stave in order to make a self bow

History


Laminated bows were rare in most of the world before modern waterproof glues became widely available, almost unknown before about 1900CE, and outside Japan and Northern Asia they have never formed a significant proportion of traditional bows. The modern Japanese yumi
