である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a resin composite base fabric.

により騒音が発生し、かつ接合強度不足の問題も
生じていた。 In addition to mechanical joining using bolts, etc., resin molded products can be joined by applying a binder and joining by the crosslinking effect of the binder, or by roughening the joint surface by sanding, etc. There is a method of joining by applying adhesive or the like. However, when mechanical joining is performed, the base material may be destroyed when forming bolt holes or when tightening bolts, and when using a binder, the toxicity of the binder itself may deteriorate the working environment and cause insufficient joint strength. There is a problem,
Furthermore, when the bonding surface is roughened, noise is generated due to sanding, etc., and there is also a problem that the bonding strength is insufficient.

つていて樹脂成形品と完全に一体化しているた

が樹脂成形品から抜けるというようなことが全く
生じない。そのため、極めて大きな接合強度（母
材破壊を生じる程度）を発揮しうるのである。 Therefore, as a result of intensive research to solve this problem, the present inventor discovered that on the back side of a cloth body woven with twisted yarn made of short fibers alone or a mixture of short fibers and long fibers, Using a bonding sheet provided with a sheet-like elastic body with a fabric embedded to a predetermined thickness, the resin molded product is formed by pressing the surface side of this bonding sheet against the surface of the resin molded product before curing. After completing curing, the bonding sheet is peeled off from the surface of the resin molded product, and the surface of the resin molded product is processed into a rough surface in which part of the resin of the resin molded product is raised in the form of threads, and this rough surface is used. He discovered that the intended purpose could be achieved by joining resin molded products using the same method, and filed a patent application (March 23, 1981).
The reason why excellent effects can be obtained by using the above bonding sheet is considered to be due to the following reasons. In other words, the side of the above-mentioned bonding sheet that is superimposed on the uncured resin molded product is made of a cloth woven with short fibers alone or twisted yarns consisting of short fibers and long fibers, so the uncured When the fabric is pressed against the resin molded product, the resin penetrates into the twists of the twisted yarn of the fabric. Then, as the resin molded product is cured in this state, the infiltrated resin will harden while entering the strands, and after curing, when the joining sheet is peeled off, it will come out from the strands and leave the surface of the resin molded product. It stands up in the form of threads and roughens the surface of resin molded products. This filament is located in the adhesive layer after bonding, and its anchoring effect makes the bond strong.In particular, it is a part of the resin molded product and is completely integrated with the resin molded product. Therefore, even if a force that causes the joint to peel off is applied, the root will never come off from the resin molded product. Therefore, it is possible to exhibit extremely high bonding strength (to the extent that it causes base material failure).
ところで、上記接合用シートは、未硬化状態の
樹脂成形品に重ねられるのであるから、その成形

好ましい。また、その裏面のシート状弾性体は、

の入り込み度合が均一であることが好ましい。ま
た、接合用シートの接合後の剥離を考慮すると、
布体とシート状弾性体とは強固に一体化している
ことが望ましい。 By the way, since the joining sheet is placed over an uncured resin molded product, it is preferably thin so that it can conform to the shape of the molded product. In addition, the sheet-like elastic body on the back side is
When the bonding sheet is stacked on the uncured resin molded product mentioned above, the penetration of the resin from the resin molded product into the fabric (of the bonding sheet) is stopped midway so that it does not reach the back side of the fabric. This ensures the releasability of the bonding sheet (if there is no sheet-like elastic material, the resin will penetrate into the entire fabric and harden, making the fabric appear to be part of the molded product and cannot be peeled off). At the same time, the length of the filament formed by the penetrating resin is regulated (when the sheet-like elastic body is deeply penetrated into the fabric, the penetration of the resin becomes shallow and the filament becomes short, In the opposite case, it will be longer). Therefore, in order to equalize the length of the filaments formed on the surface of the resin molded product and eliminate variations in adhesive strength, it is preferable that the degree of penetration of the sheet-like elastic body into the fabric is uniform. . Also, considering the peeling of the joining sheet after joining,
It is desirable that the cloth body and the sheet-like elastic body are firmly integrated.

とによるものと考えられる。 The inventor conducted a series of studies in order to produce such a bonding sheet in large quantities, rather than on a test basis. In other words, the methods involved laminating a sheet-like resin onto a base fabric, or brushing or spraying a resin solution onto the base fabric. Moreover, it is difficult to roughen the surface of the resin molded product with the resulting bonding sheet, and in method (2), the resin liquid permeates the entire base fabric, making it impossible to obtain the desired bonding sheet. In addition, we also performed topping processing on the base fabric and crimped the sheet-like rubber. However, with this method, it was not possible to make a thin bonding sheet. This is thought to be due to the fact that when the base fabric is thin, the rubber is rubbed into the entire base fabric during the topping process. Moreover, even if a thick base fabric is used, it is not possible to obtain a fabric in which the rubber material is uniformly distributed throughout the fabric. This is also thought to be due to the fact that it is difficult to rub the rubber into the base fabric uniformly over the entire base fabric.

成した。 As a result of further research, the inventor created a semi-cured resin layer on the film.
When a base fabric is placed on the surface of this resin layer and pressure is applied to embed a part of the base fabric into the resin layer, and the resin layer is cured in this state, the resin layer is thin and the degree of penetration into the base fabric is uniform. The inventors have discovered that it is possible to obtain a resin composite base fabric such as a joining sheet in which the base fabric and the resin layer are firmly integrated, and have completed this invention.

するものである。 That is, this invention creates a semi-cured resin layer of a resin that exhibits elasticity when cured on a film,
Layer the base fabric on the surface of this semi-cured resin layer, apply pressure to the extent that the semi-cured resin layer penetrates to about half the thickness of the base fabric, and in that state, the resin penetrates to about half the thickness of the base fabric. A method for manufacturing a resin composite base fabric characterized by curing a semi-cured resin layer including a layer to obtain a highly flexible resin composite base fabric having a structure in which an elastic resin layer penetrates to about half the thickness of the base fabric. This is a summary.

けたまま使用してもよい。 In this way, the present invention forms and uses a semi-cured resin layer on a film, so that the thickness of the semi-cured resin layer can be seen with the naked eye.
Moreover, the thickness can be easily adjusted. Therefore, a thin resin composite base fabric can be easily obtained by setting the thickness of the semi-cured resin layer to be thin, stacking a thin base fabric thereon, and applying pressure. In addition, it is easy to make the thickness of the resin layer formed on the film uniform throughout the film.
By making the thickness of the resin layer uniform over the entire resin layer, overlaying the base fabric on it, and applying pressure, it is possible to uniformize the state in which the resin layer penetrates into the base fabric. Furthermore, since the base fabric is layered on top of the semi-cured resin layer and the resin layer is cured with part of the base fabric pushed into the resin layer, the integration of the resin layer and base fabric is extremely strong. It will be done to you. The resin composite base fabric of the present invention may be used with the film removed, or may be used with the film still attached.

The material, thickness, etc. are free. However, when using a resin composite base fabric with the film attached,
The thinner the film, the better. Further, when the film is peeled off and used, it is required that the film has releasability.

行われる。 The resin composite base fabric is manufactured, for example, as follows. That is, an uncured resin layer is created by casting or spraying a liquid resin on a film, and after this uncured resin layer is semi-cured, a base fabric is placed on the surface and pressure is applied to semi-cure the resin. This is done by infiltrating the hardened resin into the base fabric to about half its thickness and leaving it in that state, or by heating and drying to harden the semi-hardened resin layer.

In order to cure the semi-cured resin layer, including the resin layer that has penetrated to about half the thickness of the base fabric, in this state, the elastic resin layer will be about half the thickness of the base fabric. It becomes possible to manufacture a resin composite base fabric with a two-layer structure that is highly flexible and has a high degree of penetration.
