Abstract

The invention relates to a ball game racket frame (12) including a head portion (14), a shaft portion (18) and a grip portion (20). The ball game racket frame (12) comprises a fiber composite material having fibers embedded in a matrix. At least 5% of the fibers are natural fibers in at least one cross-section (28, 28a, 28b, 28c, 28d, 28e) of a portion of the ball game racket frame (12).The invention further relates to a ball game racket frame (12) in which the proportion of natural fibers in at least one cross-section (28b, 28c, 28d, 28e) of the shaft portion (18) and/or the grip portion (20), respectively, is greater than the proportion of natural fibers in at least one cross-section (28, 28a) of the head portion (14).The invention further relates to a method for manufacturing such ball game racket frames (12).
