<p>A composite sporting implement, such as a ball bat or bat barrel, is formed with layers of continuous structural fibers embedded in a binder material having a high melting point. Such a binder does not undergo a chemical conversion process during forming of the ball bat. The layers are shaped into a preform and placed in a mold. Heat and pressure are applied to bring the binder to its melting point and to cause the binder material to flow between adjacent layers. The mold is then cooled below the binder's melting point to solidify the composite structure. A composite sporting implement formed in this manner exhibits excellent shear strength, toughness, and damping qualities.</p> |
