Abstract: A hollow fiber pipe structure includes a fiber pipe body. The fiber pipe body is hollow and formed with a through hole. The inner wall of the through hole is integrally formed with a plurality of reinforcement ribs. Each of the reinforcement ribs includes a foam material layer therein. The inner wall of the through hole is integrally formed with a plurality of reinforcement ribs to enhance the strength of the present invention greatly, and each reinforcement rib comprises a foam material layer therein so that the fiber pipe body is more compact by compressing the foam material layer. The present invention not only enhances its whole strength but also saves the use of the fiber fabric so as to lower the manufacture cost. Besides, the product is light. This is beneficial for hitting a ball.
