Why don't composite bow pieces use carbon steel?

Heat treatment of steel is the key. . This is not carbon steel. . The overstretching tension of wood chip composite laminates is more dangerous than that of metals. . Generally speaking, if the bearing capacity of the bow is 40 pounds, it must have at least 80 pounds of fracture resistance. . . In this way, whatever you pull is safe, and at most it is inelastic. . The disadvantage of carbon steel is that it is too thin and too thick, which will break and have no elasticity. . Heat treatment is the key. The quenching temperature of spring steel is too high, which will cause waste. . Deformation is too low. . Tempering is steel wire. . Go to the experiment yourself. . Generally, people with low tension will not get hurt or have an accident.
