Abstract
Reinforcement is used in the manufacture of shafts having multiple layers with multiple types of material in various combinations for the arrows, crossbow bolts, and sporting goods of the present invention. The reinforced shaft is a cylindrical tube made of a base material with a reinforcing layer applied to the cylindrical tube. In one embodiment, the reinforced shaft is a carbon fiber blank with a steel mesh used as the reinforcing layer. The reinforcing layer applied over the carbon fiber blank increases the overall strength of the shaft.
