Embodiment 1

[0017] A method of manufacturing martial arts sticks from composite materials, utilizing such as figure 1 The shown production device is produced, comprising the following steps: the reinforced polypropylene prepreg tape of aramid fiber is wound on the thermoplastic continuous fiber prepreg tape reel 1, is heated and melted through oven 2, and the temperature of oven 2 is controlled at 190-230°C, the thermoplastic resin reaches a molten state, and then is wound by a winding device, and the winding shaft reciprocates at a constant speed up and down, so that the prepreg tape is wound into a hollow structure in the direction of an inclination angle of 20° from the winding shaft 3 Stick 4.

Embodiment 2

[0019] A method for manufacturing martial arts sticks with composite materials, the method includes the following steps: winding the reinforced polyethylene terephthalate prepreg tape of boron fiber on a reel of thermoplastic continuous fiber prepreg tape, heating and melting in an oven, The temperature of the oven is controlled at 250-270°C to make the thermoplastic resin reach a molten state, and then it is wound by the winding device, and the winding shaft moves up and down at a constant speed, so that the prepreg tape is wound in the direction of an inclination angle of 35° with the winding shaft. Martial arts stick with hollow structure.

Abstract

The invention relates to a method for manufacturing a Wushu stick by composite materials, and the method comprises the following steps: heating and melting a prepreg tape of continuous fiber reinforced thermoplastic resin in an oven, and winding the tape into a Wushu stick with a hollow structure by a winding device. Compared with the prior art, the invention has a simple process and an easy operation, and allows direct molding; and the produced product has the advantages of low cost, high strength, and good shock resistance.

Description

technical field [0001] The invention relates to a method for manufacturing martial arts training equipment, in particular to a method for manufacturing martial arts sticks with composite materials. Background technique [0002] Martial arts sticks are mostly made of wood, and existing martial arts sticks are easy to corrode, easy to break, non-renewable, and do not meet the concept of environmental protection. In order to overcome the various defects of the above-mentioned materials, it is necessary to provide a good performance and cheap martial arts stick made of new materials. Continuous fiber reinforced thermoplastic resin composite material prepreg tape (see patent 200810201216.9, 200910048973.1 for details) has excellent mechanical properties such as high tensile strength, flexural strength / modulus, high and low temperature impact strength, etc., and has relatively low density and It is a new type of composite material that has the characteristics of recyclability, hi...
