Specifically, a woven fabric (woven fabric) made of thermoplastic resin fibers, reinforcing fibers, or blended yarn thereof is laminated with a thermoplastic resin sheet, and is formed by heating and pressing at a specific temperature.

０３３号。(Prior Art) Conventionally, methods for producing composites include, for example, a method in which reinforcing fiber tow or woven fabric is impregnated with a thermosetting resin and cured, or a reinforcing fiber or its woven fabric is coated with resin powder, and then processed. There is a method of melting and impregnating the tissue with the resin powder under pressure. However, these methods are not easy to handle because the prepreg intermediate is sticky and it is difficult to process the resulting composite into a complicated shape. On the other hand, recently, a method has been developed in which, for example, a continuous fiber tow containing a mixture of a thermoplastic polymer and a non-thermoplastic reinforcing fiber, particularly carbon fiber, in a specific proportion is heated to a temperature higher than the melting point of the thermoplastic polymer fiber (Japanese Patent Application Laid-open No. 1986-209
No. 033.

目的とする。(Problems to be Solved by the Invention) However, the composite obtained by the manufacturing method proposed above does not satisfy all of the required functions, and is particularly strong and reinforced with thermoplastic resin. There is a need for composites that have good wetting of fibers. Therefore, an object of the present invention is to provide a manufacturing method suitable for obtaining a composite having the above-mentioned performance with good moldability.

合体の製造方法である。(Means for Solving the Problems) As a result of intensive studies in view of the above-mentioned problems, the present inventors have laminated a thermoplastic resin sheet and a fabric made of thermoplastic resin fibers and reinforcing fibers or their blended yarns, The present inventors have discovered that a good composite material h"- can be obtained by molding by heating and pressurizing at a high temperature, and have proposed the present invention. That is, the present invention proposes the present invention. A fabric made of yarn and a thermoplastic resin sheet are laminated,
This method of manufacturing a composite is characterized in that the composite is molded by heating and pressing at a temperature that is higher than the melting temperature of the thermoplastic resin and lower than the melting temperature of the reinforcing fiber.

（容量、以下同じ）、好壕しくは３０〜９０％である。The woven fabric used in the present invention is a mixed fiber obtained by weaving the above-mentioned thermoplastic resin fibers and reinforcing fibers. That is, in such a fabric, each warp unit and each weft unit is composed of at least one thermoplastic resin fiber and reinforcing fiber, or a blended yarn of thermoplastic resin fiber and reinforcing fiber. The mixing ratio of thermoplastic resin fibers and reinforcing fibers in each warp unit and each weft unit varies depending on the thickness of the thermoplastic resin sheet to be laminated and the final reinforcing fiber content of the composite, but usually reinforcement Contamination rate of fiber for use is 5-95%
(capacity, the same applies hereinafter), preferably 30 to 90%.

On the other hand, if the mixing amount exceeds 95%, the effect of improving the wetting of reinforcing fibers by the thermoplastic resin decreases.

When using multiple layers of each fabric, such as sheet/fabric/sheet/fabric/sheet, or two or more layers of fabric, each fabric Laminated at any angle, there are 2 layers on each fabric layer.
More than one fabric can be stacked at any angle. At this time, the thermoplastic resin for the sheet and the thermoplastic resin in the fabric may be different types of resins, but it is preferable to use the same type of resin. In addition, when using glass fiber as the reinforcing HI fiber and polyolefin modified with unsaturated cargenic acid or unsaturated silane compound as the thermoplastic resin, it is particularly desirable to use the modified polyolefin for the thermoplastic resin fiber constituting the fabric. The plastic resin sheet may be either unmodified or modified polyolefin.

来る。Pressure molding is generally carried out by compression molding or extrusion lamination at the above-mentioned temperature. A preferred method is to laminate molten thermoplastic resin sheets extruded from a die extruder and press them with a nib roll. In addition, when molding by heating and pressurizing, it is preferable to fix the periphery of the fabric or apply tension to prevent shrinkage caused by melting of the resin. You can get something even better.

兼ね備えた複合体が得られる。(Function and Effect) As is clear from the above description, according to the present invention, by using a woven fabric in which thermoplastic resin fibers are present in close contact with reinforcing fibers, when molding by heating and pressurizing, Since the reinforcing fibers are completely impregnated with the thermoplastic resin, there are no voids, and the wetting is good, a composite that has both good appearance and strength can be obtained.

形状の成形物を作ることができる。Furthermore, since the present invention laminates thermoplastic resin sheets,
The resulting composite also exhibits the following effects. Conventionally, when molding the woven fabric itself by heating and pressing, a considerable amount of thermoplastic resin fiber was required to improve moldability, and when the reinforcing fiber content of the composite was kept low, required a larger amount of thermoplastic resin fibers. A woven fabric with this type of composition has a fine texture when woven, but when it is heated and pressure molded, gaps are created between the thermoplastic resin fibers when melted, and at the same time, the stretched thermoplastic resin When fibers are used, the fibers shrink and the reinforcing fiber fabric structure becomes extremely disordered, resulting in a poor appearance and a weak reinforcing effect. In contrast, in the present invention, thermoplastic resin sheets are laminated, so composite fibers with a relatively high content of reinforcing fibers are used, and the thickness of the thermoplastic resin sheets is varied to achieve the final result. The reinforcing fiber content in the composite can be changed arbitrarily, and the X1 weave of the reinforcing fiber fabric is beautiful and the reinforcing fibers are well wetted by the thermoplastic resin, resulting in excellent appearance and strength. A composite with good moldability can be obtained. Note that the composite obtained in the present invention can be molded into various (arbitrary) shapes by hot stamping molding or the like.
