What's the laminate in the bow and arrow for? Please explain it, it is better to match it.

Laminated bow is a kind of bow classified by technology. Its technical feature is that the arch back is made of different materials. The advantage of lamination is high rebound efficiency, and the shape of arch back can be adjusted as needed.

Traditional laminated bow

Generally, horns, wood and tendons are bonded together layer by layer. Several famous bows in ancient times used this technique. The bow produced by this process has high shooting speed, but the production cycle is long and it is impossible to mass produce.

Modern laminated bow

Generally called glass wood glass or glass wood glass, it refers to two layers of glass with a layer of sawdust or two layers of sawdust, glued with epoxy resin and dried in the shade for 72 hours. In the process of drying in the shade, pressure should be continuously and evenly applied to the arch back to ensure the quality. The common paving size is 40* 1.5* 1200 (unit: mm). Compared with traditional lamination, modern lamination is less efficient, but it can adapt to large-scale industrial production.
