DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for continuously manufacturing a sheet-like tape of unidirectionally aligned fiber bundles uniformly and with less generation of fuzz, etc., in connection with widening or opening of fiber bundles. Involved.

Currently, fiber bundle tapes are made of epoxy resins, unsaturated polyester resins, etc. for reinforcing carbon fibers, glass fibers, fully aromatic polyamide fibers, etc., and thermosetting resins such as epoxy resins, unsaturated polyester resins, etc. are used for fiber bundle tapes. Prepreg impregnated with the above is widely used as industrial materials such as leaf springs and honeycomb structural materials, as well as sports and leisure equipment such as fishing rods, golf shafts, and badminton shafts. Furthermore, in recent years, many studies have been conducted on the use of molding materials using the above-mentioned prepreg in aircraft materials, automobile materials, and medical materials, and some of them have even been put into practical use.

As the uses and applications of prepregs become more diverse, the need for uniform and thin prepregs tends to increase. Uniform and thin prepreg allows for a variety of designs that take advantage of the anisotropic characteristics of the unidirectionally aligned reinforced fiber-reinforced resin, without making it difficult to obtain thin-walled molded objects, further expanding the uses of composite materials. it is conceivable that.

In order to make uniform and thin prepreg, usually thin fiber bundles or fiber bundles with a small number of filaments are aligned in one direction to make a thin fiber bundle sheet, or relatively thick fiber bundles or fiber bundles with a large number of filaments are made. One of two methods is adopted: widening the fibers by some means and aligning them in one direction to make a thin fiber bundle sheet.

Generally, thin fiber bundles or fiber bundles with a small number of filaments are expensive, so it is considered advantageous to widen the thickest fiber bundles or fiber bundles with a large number of filaments as much as possible to make a thin fiber bundle sheet and convert it into prepreg.

The present inventors have arrived at the present invention as a result of various studies regarding the manufacturing method of thin prepreg sheets. That is, the gist of the present invention is to provide an apparatus having guide rolls on each of the supply side and the outlet side, and a plurality of widening rolls parallel to each other between the guide rolls. There is a fiber bundle widening device in which each widening roll is arranged so that the exit angle of the fiber bundles arranged in parallel to each other is 30 to 90 degrees.

According to the apparatus according to the present invention, it is possible to continuously and efficiently widen the aligned fiber bundle, so that when used as a part of a prepreg manufacturing apparatus, a thin prepreg of high quality can be obtained.

Figure 1(A) shows a thick fiber bundle running under tension T on the surface of a roll with radius R. Furthermore, a schematic diagram of the cross section of the fiber bundle at portions a and b is shown in FIG. 2(B).

In Fig. 1(A), if the individual fibers constituting the fiber bundle do not slip against each other in the running direction, the outermost single fiber will receive a strain of - and an excessive tension of △'r4f-H will be applied. , and is pressed inward by a force of △P.

According to this principle, the fibers running on the outside of the fiber bundle are pressed inward. At this time, when a bend is generated between each single fiber in a direction perpendicular to the running direction, each single fiber sinks inward and as a result is pushed out in the lateral direction by a force P'. If the roll is fixed at this time, the lateral weight of the single fiber in contact with the roll increases, so
It's even more effective. It is thought that this is because when the roll rotates in tandem, it becomes a stationary mass, but when it is fixed, it becomes a dynamic mass, which improves the fiber slippage in the lateral direction.

As a result of various studies on fiber bundle widening devices based on the above-mentioned principle, the device of the present invention was developed.

Below sOQ, the load on the roll due to tension becomes large, causing bending of the roll, and the occurrence of fuzz due to damage to the fiber bundles, making it impractical. Moreover, if the angle exceeds 90°, the effect of widening the fiber bundle is small, making it unsuitable for producing the desired thin prepreg. The widening roll can be rotated and fixed, and can be selected depending on the purpose. Further, SK material or stainless steel material is suitable as the material of the roll, but the surface is preferably satin-finished to improve slippage and promote widening of the fiber bundle, and to suppress the generation of fuzz. Furthermore, in order to prevent wear and endure long-term use, it is best to have the surface of the roll plated with chrome and then finished with a satin finish.

It is appropriate to use three or more width widening rolls, but if the guide rolls 4 and E are fixed rolls with a satin-finished surface, it will have a widening effect, although it will be slight. It is possible to widen the width to some extent even with a five-roll device such as No. 3.
