Field of the Invention This invention relates to a method of manufacturing a bicycle rim, and more particularly to a method of manufacturing a bicycle rim capable of producing a high temperature resistant finished product. [Prior Art] As shown in Fig. 1, the conventional bicycle rim process is mainly: a rim primordial which is formed by stacking carbon fiber prepreg and having an air bag built therein, and is placed in a temperature range of 16 generations to non-mold. In the Lai cave, and give: paragraph filling ^ procedure (first stage: wind pressure UKg / cm2, between 2 ~ 3 minutes; second stage: wind pressure 8Kg / cm2, between 35 · 8 ~ 36 8 minutes ) With the heating program ^ The thermal temperature is between 140 ° C and 150 °. 〇, to form a rim of a mold that is molded into the cavity to form an embryo. Next, the rim is taken out from the mold, and the milk in the sputum is removed. Then, the rim is placed into the embryo to sequentially perform the heat supply setting and surface processing procedures, that is, a bicycle rim finished product is obtained. However, as shown in Fig. 2, the glass transition temperature (Tg point) of the finished bicycle rim is usually low, only about 1〇〇t>c~12〇ec (U8 is shown). °C), can not tolerate high heat, and easy to soften and deform. Therefore, when riding, the friction caused by the brakes is high, and the bicycle wheel rim is easily damaged due to the poor heat resistance and wear resistance of the bicycle rim, and the overall service life is relatively shortened. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of manufacturing a bicycle rim that can improve the heat resistance of a bicycle rim. The manufacturing method of the 毛本毛明 bicycle rim, including steps 5 1308527 (4) ~ (9). In step (A)', a plurality of layers of carbon fiber prepreg are fed to form a rim embryo with an -inflated space. In step (B), the air bag is placed into the inflatable space of the rim of the rim. In the step (6), preparing - the mold 'the inner mold surface of the mold defines a cavity, and the inner rim of the rim is placed inside the mold hole, and according to = " M ^ ^ ^ —— P from the slave order to continue to inflate the air bag for the wind pressure G kg Ping Fang Gongfen between 10~20 minutes 'The second stage is the wind pressure between 3 kg, square centimeter and time between 10 to 20 minutes, the third stage is a wind pressure of 5 to 8 kg; the cent and the time is between 70 and 90 minutes, and the air bag is inflated to force the outer surface of the rim to be completely tightly attached. Combining the inner mold surface of the mold with a heating program to form a shape of the rim of the mold to form an embryo: in step (D) 'removing the rim from the mold to take out the rim, and taking out the The air bag is then subjected to a procedure of heat supply setting and surface processing in order to produce a bicycle rim finished product. The purpose of the present invention is to provide a high heat resistance and phase life of the finished bicycle rim finished product by using the three-stage inflation procedure to determine the wind pressure and time conditions 'in conjunction with the control of the mold temperature and heating temperature'.
