    摘要： A ball game racket frame includes a head portion, a grip portion and a shaft portion which connects the grip portion and the head portion. The ball game racket frame is at least partially made of at least one layer of a plurality of fibers which are randomly orientated and intertwined within the layer. According to further aspects, a ball game racket includes the ball game racket frame according to any of the embodiments described herein and a string bed plane comprising a plurality of strings which are attached to at least a portion of the head portion of the ball game racket frame. The string bed plane provides at least one striking surface for striking a game ball. According to yet further aspects, a method for manufacturing a ball game racket frame is disclosed.

    摘要： A tennis racket may include a handle with a butt end, and a head configured to support strings. The tennis racket may also include a throat connecting the handle and the head, wherein the racket may have a Power Maneuverability Ratio from about 4500 to about 7915, the Power Maneuverability Ratio governed by the equation: P   M   R = ( SW )  ( RW ) ( PUW ) , where SW=the moment of inertia in kilogram-centimeters squared of the tennis racket about a swingweight axis that is perpendicular to a longitudinal axis of the tennis racket, parallel to a tennis ball hitting surface contained by the head, and intersecting a point on the handle that is four inches from the butt end along the longitudinal axis, RW = RW - ( Wt 1000 )  ( b 10 - 10.16 ) 2 , Wt=the weight of the racket in grams, b=the distance in millimeters between a center of gravity of the racket to the butt end.
