The present invention is directed to a shaft and arrow system. The shaft and arrow system includes a hybrid structure that may include two concentric tubes. A first of the two concentric tubes may comprise an outer shell or jacket of thin- walled metal alloy. A second of the two concentric tubes may include an inner core of thin-walled fiber reinforced polymer. The two concentric tubes may be bonded together by a suitable adhesive such as epoxy or urethane. The shaft may have a reduced diameter as compared to conventional arrow shafts, and the shaft may be receptive of a variety of inserts, points, nocks, and other components. Some inserts may be completely recessed within a first end of the shaft.

La présente invention concerne un système de flèche et de tige de flèche. Le système comprend une structure hybride qui peut comprendre deux tubes concentriques. Le premier des deux tubes concentriques peut comprendre une coque ou une chemise extérieure d~un alliage métallique à paroi mince. Le second des deux tubes concentriques peut comprendre un noyau intérieur de polymère renforcé de fibres à paroi mince. Les deux tubes concentriques peuvent être liés ensemble par un adhésif approprié, tel que de la résine d~époxy ou de l~uréthane. La tige peut avoir un diamètre réduit par rapport aux tiges de flèche classiques et la tige peut recevoir une variété d~embouts, de points, d~encoches et d~autres composants. Certains embouts peuvent être complètement enfoncés dans une première extrémité de la tige.
