Embodiment Construction

[0018] The method for making a carbon fiber composite arrow shaft of the present invention will be described in detail below.

[0019] (1) Cutting: Use a large precision cutting machine to cut the high carbon fiber cloth to ensure no burrs, no tears, and vertical corners;

[0020] (2) Grease-coated core: Apply uniform epoxy resin on the core tube. The viscosity of the epoxy resin should not be too high. After 15 minutes, use an electric iron with a temperature of 60°C to 70°C and a voltage of 100V to iron the core.

[0021] (3) Rolling tube: adjust the pressure of the upper and lower plates of the large-scale tube rolling machine to 2.5~3.0MPa, check the quality of the ironing core, whether the cloth has openings, sticking obliquely, whether the front and rear pads are added correctly, and the burr should be removed in time, and the main cloth is spread out. Flat, then roll the tube. Keep the silicone plate on the coiling machine clean to prevent the material from sticking to...

Abstract

The invention provides a manufacturing method of a carbon fiber composite arrow shaft, which solves the technical problems that a present arrow shaft is heavy in weight, bad in wind resistance and straightness, small in strength and inaccurate in shooting. The manufacturing method of a carbon fiber composite arrow shaft includes the following steps: (1) a step of cutting, namely a step of cuttinghigh carbon fiber cloth by using a large precise fabric cutting machine to ensure no hairy edges, no tearing, and vertical edges and corners; (2) a step of resin coating and core ironing, namely a step of uniformly coating a core pipe with epoxy resin and ironing the core by using an electric iron after 15 minutes; (3) a step of pipe rolling, namely a step of adjusting the pressure of the upper and lower plates of a pipe rolling machine, flattening the main cloth, and rolling the pipe; (4) a step of wrapping, namely a step of wrapping the rolled arrow shaft material; and (5) a step of high temperature curing and fine grinding, namely a step of placing the arrow shaft material into a high temperature curing furnace for high temperature curing and placing the arrow shaft material into a finegrinding machine for deep fine grinding. The manufacturing method is widely applied to the technical field of arrow shaft manufacture.

Description

technical field [0001] The invention relates to a method for making an arrow shaft, in particular to a method for making a carbon fiber composite arrow shaft. Background technique [0002] The traditional one-time extrusion molding commonly used in the manufacture of aluminum arrows has low cost, but the internal stress distribution is uneven, the overall weight is large, the diameter is large, and the wind resistance is poor. After a period of use, the internal stress will cause changes in the degree of curvature, strength and straightness, which will affect the accuracy, and the wood with ordinary strength is easy to bend. The traditional pure carbon arrow shaft is made of carbon fibers arranged along the direction of the arrow shaft and then glued to form a shaft. This manufacturing process is relatively simple, but because there is no carbon fiber reinforcement in the horizontal direction of the arrow shaft, it can only rely on the strength of the glue, but the strength ...
