Description

{Apparatus for pultrusion molding of fiber reinforced composites}

The present invention relates to a pultrusion molding device for producing fiber-reinforced composite moldings, and more specifically, to a pultrusion molding device capable of efficiently manufacturing fiber-reinforced composite moldings with improved mechanical properties in the width (thickness) direction.

In general, pultrusion is a method of continuously forming products by impregnating fiber roving or mat with resin and curing it through a heated mold with a constant cross-sectional shape. It is a method of continuously forming products such as long tubes, rods, and channels. It is used to manufacture products with

The conventional pultrusion molding machine used in the pultrusion method consists of a reinforcing fiber creel, a resin bath, a forming buide, a heating mold, a puller, and a cutter. As the supplied reinforcing fiber passes through a resin impregnation device, the reinforcing fiber is impregnated with resin. Reinforcement fibers impregnated with resin are hardened into a composite material as they pass through a heated mold, and the composite product that exits the mold is continuously pulled by a pulling device. The molded composite product is cut to the desired length by a cutter and finally completed.

This type of pultrusion has the advantage of being highly productive, capable of producing products with a high fiber volume content, and producing products of unlimited length.

In the pultrusion process, several rovings, which are a combination of fiber yarns, are impregnated and then passed through a heated tunnel, where they are mixed together into bulk to produce bulky fiber bundles or groups. At this time, lack of impregnation uniformity and subsequent air retention between non-impregnated fibers may cause defects in the mechanical properties of the final product. This effect becomes more noticeable as the number of rovings increases and the final molding becomes larger.

Meanwhile, in the conventional pultrusion method as described above, reinforcing fibers are formed in the longitudinal (slant) direction of the molded product, so reinforcement in the thickness (weft) direction is difficult to achieve, resulting in cracks in the thickness direction, etc. There is a problem that the mechanical properties of the direction are weak.

For example, it is possible to manufacture thermoplastic resin moldings using reinforcing yarn coated with thermoplastic resin such as polypropylene (PP), polyethylene (PE), or nylon 6 (PA6).

Meanwhile, in the embodiment shown in Figures 1 and 2, the fiber reinforcement is laminated in four layers in the order of longitudinal direction (WP) - thickness direction (WF) - thickness direction (WF) - longitudinal direction (WP). Although a composite molding or a device for forming such a fiber-reinforced composite molding is exemplified, a fiber-reinforced composite molding or a fiber-reinforced composite molding in which two layers of thickness-direction reinforcing yarn and longitudinal reinforcing yarn are further laminated one or more times on top of the longitudinal reinforcing yarn. A pultrusion molding device for manufacturing is also available. However, since drawing is performed at the final stage as described later, longitudinal reinforcing yarns must be arranged at the outermost edge to prevent the thickness direction reinforcing yarns from being pushed by the roller during drawing. And, as described later, the reinforcing yarns in the thickness direction are wound in opposite directions.

The pultrusion molding device (1) for manufacturing fiber-reinforced composite moldings according to the present invention, which is designed to produce such fiber-reinforced composite moldings (P), alternately supplies longitudinal reinforcement yarns and thickness-direction reinforcement yarns sequentially according to the shape of the molding. It is equipped with elements that supply resin liquid in the form of a spray to impregnate the elements and each reinforcing yarn at each supplied stage, and basically includes elements that allow the supplied materials to be molded to the intended shape. .

One or more longitudinal reinforcing yarns (WP) can be supplied together in one guide hole. However, the plurality of guide holes 20a are spaced apart from each other at regular intervals to prevent the longitudinal reinforcing yarns WP passing through different guide holes 20a from clumping or overlapping.

Meanwhile, as shown in FIGS. 3 and 4, the weft creels 52 disposed in the first weft creel portion 50 are composed of two or more weft threads on one axis 53 provided on the disk 51. The creels 52 are arranged in a stacked manner, and a plurality of weft creels 52 are arranged in a stacked manner on adjacently arranged shafts 53, so that the thickness of several strands is obtained from a large number of weft creels 52 at a time. By configuring the directional reinforcing yarn (WF) to be supplied at once through one yarn guide 54, the area covered per rotation during covering is formed to be large, so even if the rotation speed of the disk 51 is not increased, the production speed is increased. It can be faster, and as a result, stable covering is achieved and quality homogeneity is improved.

In addition, in order to prevent the reinforcement yarn (WF) in the thickness direction from being disturbed during operation such as rotation of the weft creel 52, a brake function that holds the weft creel 52 is attached to the shaft 53 to maintain the tension of the yarn. do.

Meanwhile, the yarn guide 54 is divided into a support part 54a fixed to the disk and a hollow guide rod part 54b screwed to the tip of the support part 54a, as shown in FIG. 5, and the support part 54a ), assembly and disassembly are possible by coupling between the threaded bolt hole (54a-a) formed at the tip of the guide rod portion (54b) and the threaded thread (54b-a) formed on the upper outer diameter of the guide rod portion (54b), and in particular, the thickness direction reinforcing yarn (WF) ) can be adjusted in height so that it can be supplied to the correct location.

A second weft creel unit 70 is disposed in front of the second injection unit 60.

The second weft creel portion 70 may be composed of the same elements as the first weft creel portion 50, except that the disk 71 rotates in the opposite direction to that of the first weft creel portion 50, The thickness direction reinforcing yarn (WF) supplied from the weft creels 72 of the second weft creel portion 70 is configured to cover in the opposite direction to the covering performed in the first weft creel portion 50.

A third spraying unit 80 is disposed in front of the second weft creel part 70 to spray a resin solution so that the thickness direction reinforcing yarn (WF) covered in the second weft creel part is impregnated and sprays a predetermined resin solution. I do it.

Meanwhile, a second inclined creel unit 90 in which a plurality of inclined creels 91 on which longitudinal reinforcing yarns (WP) are wound is disposed is disposed at the front part of the third injection unit 80 in the moving direction. 2 A second guide guide 100 is disposed in front of the inclined creel portion 90.
