The present invention relates to a three-dimensional multilayer structure base material in which fibers are arranged in the thickness direction within the body.

る。When manufacturing fiber-reinforced composite materials, materials such as resins, which cannot be sufficiently strong with a single material, are reinforced with reinforcing materials such as fibers and textiles, and are combined (so-called base materials). m for the material to be reinforced (the so-called matrix)
Reinforcement methods that are often used to obtain relatively high-strength composite materials with relatively high filling rates include the filament wein- taining method, in which continuous fiber bundles such as Low Pink are wound, and the method in which woven fabrics are woven to the required thickness. The fabric lamination method is used by laminating layers.

丁べつを生し易い欠点を有している。Composite materials made by these methods can obtain great strength in one direction of fiber arrangement, but because they have a laminated structure in which rovings or woven fabrics are stacked to the required thickness, it is difficult to combine low pink and low pink or woven fabrics. Bonding strength between (interlaminar strength)
The resistance is small and acts in the direction perpendicular to the laminated surface of the roving or woven fabric: It has a small resistance to peeling force and the plying force that acts in the direction perpendicular to the laminated surface, causing peeling on the laminated surface. It has the disadvantage of being prone to cracking.

。However, in the suturing method using a sewing machine, the fibers of the laminated fabric and the fibers for sewing are cut by the needle that penetrates the fabric during suturing, or the thickness of the fabric to be sewn is caused by the use of a sewing machine. FJ for suturing
The disadvantages are that the laminated fabric is tightened by the fibers and the fiber arrangement is disturbed. In addition, in the above-mentioned three-dimensional fabric, the weaving operation of three-dimensionally weaving the threads and raw pink is complicated, and the equipment for that purpose is also complicated, which poses a major obstacle in increasing speed and automation.

る。In addition, the three-dimensional multilayer structure base material mentioned above generally has the following characteristics:
Although it is used as a reinforcing base material for fiber-reinforced composite materials, it can of course be used for other purposes. As an example, Figures 2 and 3 show a cylindrical three-dimensional multilayer structure base material. To explain the manufacturing method and apparatus, the support body 10 supporting the laminated base material 1 has a cylindrical shape that is rotationally driven by an appropriate drive device, and the laminated base material 1 whose end layers are layered to a required thickness and mm3 for interlayer reinforcement are formed. The laminate with the web 4 is held on the cylindrical support lO while being rolled up one after another.

圧ジェット流の圧力によって変位し。In this case, the jet stream 1 is generated within the laminated base material 1.
The fibers and FIUM bundles moving in the direction of travel of 2 are displaced by the pressure of the high-pressure jet stream.

層面に対して直交する姿勢で再配列される。The jet stream travels straight towards the support 10. and,
The living room reinforcing m male 3 that has entered the laminated base material 1 receives the thrust of the high-pressure jet stream 12 that advances straight toward the surface of the support 10, moves along the jet stream, and removes the lamination of the laminated base material 1. Rearranged to be orthogonal to the plane.

大きくなるため、積層面に直交する姿勢が保持される。When the jet stream 12 reaches the surface of the support lO, the jet stream collides with the support surface and flows out as a decelerated flow, but as a result of the deceleration of the jet stream, the rearranged interlayers are 1m for reinforcement! 3.3°... is the laminated base material l
Since the restraining force due to the fibers is greater than the acting force due to the jet flow 12, the orientation perpendicular to the laminated plane is maintained.

A thin high-pressure jet stream 12 is ejected from the laminated base material 1 while changing its relative position with the laminated base material 1 due to the rotational movement of the support body 10 and the movement of the nozzle 11 along the rotation axis of the support body. On the other hand, high pressure jet flow 1
2 effects are given. The thickness of the laminated base material 1 is determined by laminating the laminated base material 1, which is made by laminating the web 4 of the living room reinforcing fiber 3 on top of the laminated base material l to which the high-pressure jet stream 12 has been applied, and placing the nozzle on top By injecting high-pressure jet flow 12 from 11, yJR can be adjusted freely.
