Problems solved by technology

But the defect of this method is: the air bag is routed complicatedly, is scrapped easily, and the caliber of each part of the air bag is the same, and at the bending part and the variable diameter part of the rim blank, the air bag is wrinkled, so that the carbon fiber will shrink after being heated. Flow into the folds, causing the inner wall of the rim to form irregular protrusions and make it not smooth, resulting in low yield

Embodiment 1

[0040] Such as figure 1 Shown, be a kind of new craft of making carbon fiber rim of the present invention, specifically comprise the following steps:

[0041] ⑴The knife part of the carbon fiber rim is made in the following way:

[0042] ① Make the mandrel of the knife part with the same shape as the knife part;

[0043] ② Apply liquid glue on the outer surface of the knife mandrel until the liquid glue is completely covered on the knife mandrel; in this embodiment, the air duct glue is used to add a curing agent to form a liquid glue, and the air duct glue can be painted On the outer surface of the mandrel with any shape, it also has the function of a traditional air duct air bag, and its elasticity (toughness) is better than that of a traditional air bag;

[0044] ③ Paste carbon fiber cloth on the mandrel of the knife part covered with liquid glue to form a semi-finished product of the knife part wrapped with carbon fiber cloth;

[0045] 4. Put the half-finished knife par...

Embodiment 2

[0061] Such as figure 2 As shown, it specifically includes the following steps:

[0062] ⑴The knife part of the carbon fiber rim is made in the following way:

[0063] ① Make the mandrel of the knife part with the same shape as the knife part, and the mandrel of the knife part is made of Styrofoam material;

[0064] ② Coating liquid glue on the outer surface of the mandrel of the knife part until the liquid glue completely covers the mandrel of the knife part. In this embodiment, latex is used to add curing agent to become liquid glue;

[0065] ③ Paste carbon fiber cloth on the mandrel of the knife part covered with liquid glue to form a semi-finished product of the knife part wrapped with carbon fiber cloth;

[0066] 4. Put the half-finished knife part with the knife part mandrel built-in by step 3. into the mold cavity of the forming mold;

[0067] ⑤Press and heat the mold cavity, the pressure is 30kg / cm 2 , the heating temperature is 160°C, the liquid glue is solidifie...

Embodiment 3

[0082] The difference between this embodiment and Embodiment 2 is that the frame of the carbon fiber rim is made by the traditional air bag molding method, and the finished knife part obtained in step (1) and the finished frame part obtained in step (2) are combined and spliced ​​together. Get the finished carbon fiber rim.

[0083] In other embodiments, in the step ⑴ of ⑤, the set temperature is 120-180°C; in the step ⑴ of ⑤, the pressure when applying pressure and heating the mold cavity is 15-30kg / cm 2 , the heating temperature is 100-180°C; in step (1)-6, the cooling temperature when cooling the mold cavity is 55-65°C.

Abstract

A novel process of manufacturing a carbon fiber rim is disclosed. According to the process, (1) at least a tool portion of the carbon fiber rim is prepared by: 1) manufacturing a tool portion mandrel having the same shape as the tool portion, 2) coating the external surface of the tool portion mandrel with a liquid adhesive, 3) adhering a carbon fiber cloth to the tool portion mandrel coated with the liquid adhesive, 4) putting a semi-finished product of the tool portion into a cavity of a forming mold, 5) pressurizing, heating the cavity, allowing the liquid adhesive to cure, inflating the position between the liquid adhesive and the tool portion mandrel, and stopping heating until the temperature in the cavity reaches a set temperature, 6) cooling the cavity, 7) opening the forming mold to obtain a finished product of the tool portion, and 8) removing the tool portion mandrel and the liquid adhesive in the finished product of the tool portion to obtain the finished product of the tool portion. The carbon fiber rim prepared by the process is hollow and is light in weight and light and convenient to use. The process avoids the disadvantage that the yield is low in traditional airbag forming methods, and overcomes the technical problem that traditional airbag wire arrangement is complex and easily scrapped. The process is simple in manufacturing process, and increases the yield.

Description

technical field [0001] The invention relates to a new process for making carbon fiber rims. Background technique [0002] The carbon fiber rim is mainly composed of the knife part in the middle and the frame part around the periphery. At present, the common manufacturing methods of carbon fiber rims are filling molding method and air bag forming method, both of which are integrally formed of carbon fiber rims. Among them, the compression molding method is to fill the cavity of the molding die with carbon fiber material, apply pressure and heat to form it to obtain a carbon fiber rim. However, the carbon fiber rim made by this method is solid and therefore heavy. [0003] The air bag molding method is to place the rim blank formed by stacking carbon fiber prepreg materials with an air bag inside into the cavity of a mold with a temperature between 160 and 170°C, and apply a two-stage inflation process and heating The procedure is to form a rim blank with a shape that fits ...
