2. Description of the Related Art It is a well-known fact today that bonding a ceramic plate and an ACM plate can be an impact-resistant body against objects falling from a high place or objects flying at high speed. In recent years, it has also been practiced in foreign countries to bond a ceramic curved plate (usually one having a curved surface on both sides) to an ACM curved plate. However, in the case of a curved plate, the damage near the apex of the ceramic curved surface is large, and when a ceramic seam comes near the center near the apex, when a very large impact is given, the damage to the ACM at the rear of the composite molded product is also damaged. There is a large phenomenon that the function as an impact-resistant body is reduced, and it is necessary to further improve this point.

SUMMARY OF THE INVENTION According to the present invention, when ceramics of a predetermined shape are arranged in a predetermined number in combination on an ACM curved plate, a relatively central portion (a portion for receiving a high-speed flying object at a right angle) of the molded product is provided. If there is a seam, it is understood that the impact resistance decreases when a high-speed flying object collides with the seam.As a result of various examinations, when arranging ceramics, make sure that the seam of ceramic does not come to the center of the molded product. By doing so, it was found that even if a high-speed flying object collides with the central part, it is possible to obtain almost the same impact force as the other parts, and it is clear that the bridge shape of the ceramic cross section will further increase it , Reduces the separation of ceramic and ACM,
This has led to the completion of a composite molded article excellent in impact resistance with extremely small swelling on the back surface of M.

In order to obtain ACM, in the case of a thermosetting resin,
A prepreg is prepared by impregnating or coating a high-strength fiber with a thermosetting resin, a compression molding method in which a plurality of prepregs are stacked and heated and pressed, or a hand lay-up method in which a prepreg is not formed. The resin content can be in the range of 5 to 80% (% by weight, the same applies hereinafter), but is usually 5 to 80%.
It is 50%, preferably 8 to 30%. On the other hand, in the case of a thermoplastic resin, a high-strength fiber and a sheet-like material such as a thermoplastic resin film or a woven fabric are alternately stacked and heated or pressed, or a compression molding method in which the resin is melted in advance and the resin is melted. There is also a method of adhering to a high-strength fiber. The content of the thermoplastic resin is the same as that of the thermosetting resin.

As a method of fixing ceramics on the surface of the ACM obtained by the above method, as shown in FIG.
On the curved part on the back of the ceramic and on the surface of the ACM,
It is desirable that the resin used for the ACM or a method of bonding with an adhesive such as a synthetic rubber or epoxy resin is used.
In some cases, there is a mechanical joining method using a port, a rivet, or the like. In the case of arranging a plurality of ceramics by bonding, the gap between one piece and the adjacent piece is preferably small, and is preferably 0.3 mm or less to improve impact resistance. Further, it is better not to apply an adhesive to a contact surface between one piece and an adjacent piece. This is because a piece of ceramic is considerably destroyed when subjected to an external impact, but the fracture does not propagate to the next ceramic. In order to further improve the impact resistance of the thus obtained ceramic / ACM composite molded article, there is a method of further wrapping the composite molded article in ACM as described in Japanese Patent Application No. 6-213000.

As described above, a composite molded article is manufactured by arranging a predetermined number of bridge-type ceramics. In the present invention, as shown in FIGS. To obtain a ceramic / ACM composite molded product. This reduces the area that is destroyed by the impact force when an object having a large impact force or a high-speed flying object collides with the center portion, for example, as compared with a composite molded product made of ceramics having a joint at the center portion B. In addition to this, the peeling of the adhesive layer between the ceramic and the ACM can be reduced, and the bulge at the rear of the ACM can be reduced. As shown in FIGS. 5 to 8, by arranging ceramics in a staggered shape, unlike the case of a grid shape as shown in FIG. However, the ACM is not significantly damaged by the impact force. Also, as shown in FIGS. 5 to 8, it is important in terms of function and operability to form a symmetrical shape in the vertical and horizontal directions or in the vertical and horizontal directions, for example, when worn on a body or the like. Hereinafter, the present invention will be described with reference to the drawings.
