In general, composite materials are composite materials that improve the overall properties of materials by mixing two or more materials. In general, there are composite materials such as FRP (Fiber Glass Reinforced Plastics) The composite material is used as a composite material in which a high strength fiber material such as carbon fiber, glass fiber, and aramid fiber is laminated and cured by impregnating a resin (thermoplastic resin, thermosetting resin) into a mold.

The position of the mold 310 between the braiding machine 100 and the winder 200 is determined by the position of the mold 310 in the braiding machine 100 and the position of the guide 310 of the winder 200 222 allow the fibers 500 of the bobbin 221 to be wound up in the vertical direction as much as possible with respect to the longitudinal direction of the mold 310, ie, the guides 222 of the winder 200, The mold 310 is positioned and moved within the range in which the mold 310 protrudes so that the fibers 500 are fed by the guide 222 to be close to 90 degrees with respect to the longitudinal direction of the mold 310. [

Referring to the flow chart of FIG. 8, a hollow type preform manufacturing method according to the hollow type preform manufacturing system will be described. First, as shown in FIG. 3, the mold preparing step S1 is a hollow type The mold 310 is prepared so as to have an external shape corresponding to the internal structure of the preform to be manufactured. The mold 310 is formed in a cylindrical shape 3, the mold for wheel rims is shown in a simple structure in the preform manufacturing system, and the actual mold for wheel rims is formed in the longitudinal direction And a large number of irregularities are formed.

More specifically, there is no restriction according to the outer shape of the preform by the manufacturing system according to the present invention. The thickness of the preform to be manufactured may be constant along the longitudinal direction, and the diameter and cross- And the thickness of the preform to be manufactured may vary depending on the length direction. Also, since the preform to be manufactured may have a large irregularity along the length direction, the mold 310 having the hollow internal structure of the preform to be manufactured ).

In this way, in the braiding step S2, the braid is braided to the surface of the mold 310 by the braiding machine 100 and the fiber 500 is wound around the braid braided by the winder 200 in the winding step S3 , The winding step (S2) and the winding step (S3) are repeated to have a desired thickness, strength, and external shape. When the preform to be manufactured has a different thickness along the length direction, (Thickness, number of turns) of the wire 500 can be adjusted by adjusting the thickness of the wire 500. In the case of a product having a thickness varying along the longitudinal direction such as a wheel rim of a vehicle, .

The clearance step S4 further includes winding the fibers 400, 410, 420 connected to the braid braided on the surface of the mold 310 by the braiding step S2 and the winding step S3, The fibers 400 and 410 supplied from the braiding machine and the fibers 500 supplied from the winding machine 200 are wound on both sides of the mold 310, And the cut fibers 400, 410, 420, and 500 are attached so that they do not fly, thereby completing the production of the preform on the surface of the mold 310.

Finally, the collection step S5 is a step of collecting the mold 310 in which the fibers 400, 410, 420, and 500 are arranged, and the mold 310 including the preform is separated from the fixture 320 When the robot is applied to the transfer means 330, the robot moves the mold 310 and the fixture 320 together with the mold 310 and the fixture 320 together. The mold 310 or the fixture 320 including the mold 310 can be collected by moving the mold 310 to the side where the mold 310 is taken out and taken out of the winder 200. The collected mold 310 includes a preform, The manufacture of the hollow type preform is completed.

In addition, even if there is irregularity on the surface of the mold 310 for manufacturing the preform, since the braid located at the groove (concave / convex) portion by the winding is in close contact with the surface of the mold 310, the preform is manufactured by winding the fiber like the designed product, The product manufactured by the preform has a high volume ratio of fibers, uniform quality and physical properties as a whole, and excellent strength and rigidity.

Since the preform is manufactured by repeatedly moving the mold 310 between the braiding machine 100 and the winder 200, the preform production space is minimized and the preform can be easily manufactured.

Thus, the hollow type preforms manufactured according to the present invention are uniform as a whole, have excellent heat resistance and high strength, and thus can be applied to the rim of an automotive wheel, The present invention can also be applied to a long flight engine. In addition, the manufacturing system and the manufacturing method of the preform according to the present invention are characterized in that a hollow type preform having a different sectional shape along the longitudinal direction can be manufactured.
