造基材に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a three-dimensional multilayer structure base material for use as a fiber-reinforced composite material. The present invention relates to a three-dimensional multilayer structure base material in which fibers are arranged in the thickness direction.

がある。[Prior Art] When manufacturing fiber-reinforced composite materials in which a material such as resin, which cannot have sufficient strength with a single material, is reinforced with a reinforcing fiber aggregate (so-called base material) such as fiber or fabric, The filling ratio of fibers to the material to be reinforced (so-called matrix) is large,
Reinforcement methods that are often used to obtain relatively high-strength composite materials include the filament winding method, in which continuous fiber bundles such as rovings are wound, and the textile lamination method, in which textiles are laminated to the required thickness. and so on.

べりを生じ易い欠点を有している。 Composite materials made by these methods have great strength in the fiber arrangement direction, but because they have a laminated structure in which rovings or woven fabrics are stacked to the required size, the bond between rovings and woven fabrics is weak. The force (interlaminar strength) is small, and the resistance force is small against peeling force acting in a direction perpendicular to the laminated surface of roving or textiles, and shear force acting in a direction perpendicular to the laminated surface, and It has the disadvantage of being prone to peeling and slipping.

なる。 As reinforcing base materials that compensate for these drawbacks, there are multilayered fabrics made by laminating fabrics to the required thickness and sewn together using a sewing machine, and three-dimensional fabrics in which threads and rovings are woven in the thickness direction of the fabric. Proposed.
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 limited due to the use of a sewing machine. In addition, the laminated fabrics are tightened by the stitching fibers, and the fiber arrangement is disturbed. Furthermore, in the above-mentioned three-dimensional fabric, the weaving operation for three-dimensionally weaving yarns and rovings is complicated, and the equipment for this is also complicated, which becomes a major obstacle in increasing speed and automation.

By using short fibers that can be arranged in the original textile arrangement, there is no damage to the fibers, unnecessary tightening of the fiber aggregate, or disturbance of the fiber arrangement, and it can be formed to any thickness, and is simple. The purpose of this invention is to obtain a three-dimensional multilayer structure base material that can be manufactured by a mechanical mechanism.

The action of stream 12 is given. The thickness of the laminated base material 1 is such that the laminated base material 1 is further laminated with a web 4 of interlayer reinforcing fibers 3 on top of the laminated base material 1 to which the action of the high-pressure jet flow 12 is applied, and the nozzle 11 is placed on top of the laminated base material 1 which is further laminated with the web 4 of the interlayer reinforcing fibers 3.
