Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pile material for cellulose resin. In fiber reinforced resin (hereinafter referred to as FRP)
The form of AM material for reinforcing resins is as follows.

It is generally well known that textiles are used.

A common method of manufacturing FRBs consists of laminating layers of fabric, impregnating the fabric with a material such as a thermosetting resin, and then curing the resin.

However, laminating fabrics is complicated, and depending on the lamination condition, the physical properties of FRP may take an unfavorable direction. Namely.

The tensile strength of the fabric in FRP in the diagonal direction is extremely low. At the same time, it has the disadvantage of low shear stiffness in the plane direction.

Therefore, it is desired to design a fiber-based material for reinforcing resin that does not have the above-mentioned problems.

The object and object of the present invention is to solve the above-mentioned drawbacks of the conventional resin reinforcing fiber materials, and to have a high working sigma rate when manufacturing FRP, uniform physical properties, and high strength.

It is an object of the present invention to provide a method and device for integrally fabricating fiber laminated materials that have daylight resistance and stiffness.

Pregnancy, therefore, non-invention.

(1) When aligning the yarn groups and combining them with the fabric, multiple layers of sheath-like yarn groups made of yarns aligned in a + row are stacked so as to intersect with each other for 7F5 suspension. , a manufacturing policy for fiber laminates that focuses on integrating a sheet consisting of a group of eye threads and a fabric.

+2+ In a device for accumulating and integrating sheet-like yarn groups into a 7i5 woven fabric.

B. A yarn supply device that attaches and supplies a group of yarns.

and a device for pressing and gripping the supplied sheet-like yarn group and the fabric.

. . . to integrate the sheet-like yarn group and the fabric.
The present invention is an apparatus for producing a fiber laminate, characterized in that it comprises a device for relatively rotating the yarn supplying device and the pressing and gripping device.

What is the fiber material for fiber reinforced resin in the present invention?

Glass fibers, carbon fibers, silicon-based #Ij fibers, polyester yarn fibers, polyamide fibers, aromatic polyamide fibers (including aramid fibers), wholly aromatic polyester yarns, and other known reinforcing fiber materials are shown. 1. These reinforcing fiber materials may be composed of a single type, or may be composed of a combination of different materials. In addition, such materials are 9
It is more preferable if it can also be used as a sewing thread, which is the integrating means of the present invention.

The reinforcing fiber material may be filament, stable fiber, or any material that exhibits a fiber shape. When staple fibers are used, they are twisted or formed into a fiber shape using a binder or resin.

In the present invention, the fabric may be any known fabric such as woven fabric, side cloth fabric, or non-woven fabric. Among these, particularly preferred fabrics are woven fabrics. This is the vertical direction.

This is because the strength in the horizontal direction is the best, and the strength of the fabric composition is the highest. Also, among glass fibers, carbon fibers, silicon fibers, etc., textiles are the easiest to process.

This is because it is also easy to handle.

In the uninvented method, sheet-like yarn groups consisting of yarns arranged in 12+ rows are superimposed on a fabric so as to intersect with each other. Such a sheet-like yarn group is a group of many yarns arranged in a row.

This shows a sheet that has been expanded flat.

Preferably, a woven fabric is used as the fabric, and the sheet-like yarn groups are laminated so as to be intersected with each other in the warp or weft direction of the woven fabric.

The number of laminations of the sheet-like yarn group can be any number as long as it is plural. Moreover, one or more layers of fabric may be stacked.

Additionally, the present invention is to integrate the above-mentioned laminate.

Although known means such as contacting, sewing, etc. can be used for the integration, it is preferable to integrate by sewing.

Any known stitching structure may be used. Preferably, a sewing machine is used to perform lock stitches, single chain stitches, double chain stitches, etc., and the shape of the seams may include single chain stitches, zigzag stitches, and dotted zigzag stitches. Of course, the present invention may be applied to other known methods as described above. Further, the seam direction is preferably the warp or weft direction of the fabric. This is because the laminate tends to move easily during sewing.

In the non-inventive method, as long as a plurality of sheet-like yarn groups are laminated on the fabric, it may be laminated in any manner. For example, in the case of fe, diagonal sheet-like yarn groups may be laminated on both sides of the object, or may be laminated on one side. The arrangement direction of the yarns in the sheet-like yarn group is I.

Since the fabric is made of warp threads and weft threads, it is best to make it at an angle of approximately 45 degrees to the warp threads and weft threads.

Also, the thickness of yarn groups, single yarn thickness, and fabric thickness.

The thickness of the laminate can be arbitrarily selected.

Next, the method of the present invention will be explained with reference to the drawings. The $1 diagram is a non-inventive preferred process diagram. The yarn package cage 1 is layered on a creel on the frame 6, the yarn groups 7 and 8 are pulled out, and fed to the pressing and gripping means 10 through the guide groups 2 and 3.
On the other hand, the fabric 9 is supplied to the pressing and gripping means 10.

Then, fold the thread groups 7 and 8 diagonally.

Gives relative rotation. As a result, the sheet-like yarn group 7.
8 so that they cross each other.

Here, the sheet-like yarn group is as shown in Figures 2 and 6.

They are arranged in two parallel rows, 977170
When the rotational speed and the advancing speed of the threads become equal, the thread groups intersect in a diagonal pattern at an angle of approximately 45 degrees with respect to the horizontal direction. FIG. 6 shows such a basic principle diagram.

After laminating the fabric 9 and the thread groups 7, 8, the laminated body 16 is integrated with the suture thread 16 using the sewing means 11, 12. During such integration, work operability will be better if the laminate is held by the pressing and gripping means 10 and 14 and tension is applied.

Next, the second invention of the present invention will be explained.

The apparatus of the present invention is as shown in FIGS. 1 to 5.
．． A means for layering the yarns, for example, a yarn supply device consisting of a beam 1 and guide groups 2 and 3 for guiding the yarn, and a device for pressing and gripping the supplied sheet-like yarn group and the fabric 9, such as a nip roller. and a ten means for integrating the laminated body consisting of the seal group and the fabric; It has the function of rotating the Here, "relatively rotating" may be any means that fully rotates the yarn group between the guide groups 2 and 5 and the pressing and gripping device 10; for example, the pressing and gripping device 10
by fixing the guide group 2.6 and rotating the guide group 2.6 in synchronization with the frame 6, or fixing the thread supply device and rotating the guide group 2.6 by fixing the
t10. Fabric 9. The suturing device or the like may be rotated.

In the above, the guide groups 2 and 5 may be of any type as long as they have the function of keeping the supplied yarn in a sheet shape and transporting the yarn in the same rotational direction. For example, as shown in Figure 2, the jig 17 feeds the threads 7 and 8 independently.
In addition to the guide 2゜3 with a guide 2.3, other means such as rotating using a spiral grooved bar can also be used. Also, the pressure gripping device y
When rotating a device of It, 1o or less, a fixed guide may be used.

In FIG. 1, 4 is a rotating shaft, 5 is a creel support member, 11 is a sewing needle, and 12 is a hook.

Next, an example of a device for transporting the guide group 2.3 in the same rotational direction will be described. FIG. 4 is a cross-sectional view of the guide transfer device, and FIG. 5 is a plan view thereof. Guide 2
moves on the rail 17 and is pushed in fourteen directions by an arm 1F3 protruding from the machine 20. After passing the straight rail, the guide 2 is sent from the arm 18 to the riplock 1 rotating section 21. In the rotating section 21, the material is sent in one direction by another transfer means.

In the present invention, another reinforcing yarn may be inserted into the reversed portion, that is, the end portion of the sheet-like yarn group.

By inserting such reinforcing threads, the ears are significantly strengthened.

The laminate according to the second aspect of the present invention may be used as it is as a reinforcing material, but preferably about 2 to 50 laminates are used.

The laminate of the present invention is used in a stacked manner. When stacking a plurality of such laminates of the present invention, it is necessary to integrate them by stitching or by laminating them together. The stitch interval during integration by suturing is preferably about 1/2 of the thickness of the entire laminate to about the thickness of the entire laminate. Further, it is preferable that the interval between the stitch rows is also approximately the same as the above-mentioned stitch interval.

It is preferable that a plurality of stacked laminates according to the present invention be impregnated with a resin and used as a molding material.

Next, the effects of the present invention will be explained below.

A. Since the stacked sheet-like yarn groups are stacked at almost right angles, the tenacity utilization rate is high.

B. Materials with poor workability that cannot be turned into m-products.

For example, even non-flexible materials can be laminated.

It can be used as a reinforcing material.

C. The basis weight of the sheet-like yarn group can be changed freely.
It can be easily made thicker or thinner depending on the object.

D. As for the sheet-like yarn group, it is not necessary to process it into a fabric such as a woven fabric, so that the ramming body can be obtained at a lower cost.

E, compared to the conventional contact laminate of prepreg boards.

Since the sewing strength can be increased, delamination can be prevented.

F. Since the sheet-like yarn group has enemy fibers arranged in one direction, it is easy to be impregnated with resin due to capillary phenomenon during resin impregnation, and easy to process.

G8 production has good operability, so laminates can be manufactured efficiently.
