Generally, a prepreg is an intermediate base material of a fiber-reinforced composite material, and is a molding material preliminarily impregnated with a matrix resin in a reinforcing fiber. The prepreg is formed in a state of being wound around a branch pipe in a state of being combined with release paper, The prepreg is separated from the releasing paper, prepregs are stacked, and the resin is cured by heating and pressing to produce a molded product of the fiber-reinforced composite material.

For example, in a general manufacturing system of a prepreg applying a thermoplastic resin, a reinforcing fiber (yarn or sheet) wound on a roller is prepared, and a curing agent (epoxy series) contained in the reinforcing fiber is subjected to a de- the thermoplastic resin film and the releasing paper are laminated to each other, passed between the upper and lower heating rollers, pressed with a suitable pressure, passed through a plurality of heating rollers, A prepreg in which the releasing paper is integrally attached to one surface of the reinforcing fiber is wound around the paper tube by the winding device or the releasing paper is removed in front of the winding device and the thermoplastic resin The impregnated reinforcing fibers are wound around the branch pipe by a winding device to complete the preparation of the prepreg, Examples of the method for manufacturing the prepreg of applying the resin is published in the Republic of Korea Patent Application No. 1991-0021769.

In addition, in Korean Patent Registration No. 0488752, when a prepreg formed by impregnating a base material with resin and semi-cured is cut into a predetermined size, the surface of the prepreg is irradiated with a laser light beam, The resin of the irradiated portion is softened while the position is moved on the prepreg image, the softened resin portion is cut by the cutting blade, and the cutting blade cuts the portion of the resin-softened prepreg, Discloses a method of cutting a prepreg that is not scattered and a cutting apparatus, and the cutting blade specifies cutting blades such as guillotine, rotary cutter, shearing blade and saw blade.

The cutter 510 may include a circular cutter (not shown), which is widely used for slitting the existing prepreg manufacturing system And the circular cutter is configured to be movable up and down so that the circular cutter positioned on the prepreg is moved to a position The circular cutter is rotated, and the prepreg is slitted by the movement of the prepreg.

As shown in Figs. 5 and 6, when a cutter having a one-piece structure is generally used and the cutter 510 is configured to be rotatable by control at a certain angle, The cutter 510 has a structure in which the cutter 510 is rotated and slipped by the movement of the prepreg while being positioned so as to pass through the prepreg. In addition, as shown in FIG. 6, When the guide plate 520 is further provided to cover the surfaces (upper and lower surfaces), the guide plate 520 keeps the prepregs flat to make it easier to slit. In the past, However, since the prepregs manufactured according to the present invention are uniform along the longitudinal direction, a single-element cutter may be applied, and such a single-cutter may be used.Reduce manufacturing costs for the system are more simple features.

Finally, as shown in FIGS. 2 and 5, the winding unit 600 winds the completed prepreg on the paper tube, and when the paper tube is wound on the paper tube for a predetermined length, the measuring unit (encoder or the like) And a cutter (not shown in the drawing, a cutter for cutting the fabric in the width direction is generally used in the field of weaving machines, so a detailed description is omitted) is further provided in front of the winding part 600, Is cut in the width direction of the prepreg.

More specifically, the winding unit 600 is constituted by a roller rotated by a separate winding motor 620, a branch pipe is put on the roller, a prepreg made on the branch pipe is wound, and the roller is wound on a winding motor 620, the prepreg is cut by a cutting machine, and the prepreg is wound in an appropriate amount in the paper tube.

The uniform prepreg manufacturing system according to the present invention includes a material supplying unit 100, a forming unit 200, a release paper removing unit 300, a pulling unit 400, and a winding unit 600, The main motor 700 of the pulling part 400 for pulling the yarn of the material supplying part 100 and the thermoplastic resin film and the release paper are separately constructed from the winding motor 620 of the winding part 600, The heating roller 210 and the cooling roller 220 and 220 'of the forming part 200 are formed to have the same diameter and the pulling part 400 and the heating roller 210' The feed rate of the yarn and the production speed of the prepreg are kept constant to uniformly maintain the quality of the prepreg along the length direction.

The temperatures of the heating rollers 210 and 210 'and the plate heater 230 of the forming unit 200 are changed according to the moving direction of the yarn to facilitate laminating, The characteristics that the degree of impregnation of the thermoplastic resin with respect to the yarn and the degree (thickness) of the laminating can be controlled by changing the speed of the rollers 210 and 210 'and the cooling rollers 220 and 220' have.

For the sake of reference, the material supplying unit 100, the forming unit 200, the releasing paper removing unit 300, the drawing unit 400, the winding unit 600, or the material supplying unit 100, the forming unit 200, The guide rollers that rotate freely are disposed at a plurality of positions between the reject 300, the pulling unit 400 and the winding unit 600 to allow the materials to move while maintaining a proper tensile force, A wheel is provided on each of the lower part 200, the release paper removing part 300, the pulling part 400, and the winding part 600 to facilitate movement.
