Question: What is the best material for a tennis racquet?
Answer: Because of its high stiffness-to-weight ratio, graphite is the preferred frame material in the better racquets. The graphite used in racquet frames is not the true graphite you would find in a pencil, but a carbon fiber that adds stiffness and strength to the plastic resin with which it is mixed to form a frame. When a racquet is made of resin and graphite alone, it is called 100% graphite, even though it is at least 40% resin. If other materials are used, the frame is called a composite. The quality of a composite frame depends largely on the amount of graphite. Some composites are too flexible for advanced players.
