Method for producing a connecting tube interconnecting the shaft and the handle of a racket |
摘要 |
A method of producing a connecting tube that interconnects the shaft and the handle of a racket includes the steps of performing two foamed preforms which cooperatively form a foamed layer; placing the two foamed preforms around an internal impregnated fiber wall of the connecting tube; wrapping predetermined layers of impregnated fibers around the two preforms to form an external impregnated fiber wall; and heating the internal and external impregnated fiber walls and the preforms in a mold to allow the internal and external impregnated fiber walls and the preforms to connect integrally.
