Description

Composite laminates and joints

The present invention provides a composite laminate capable of bonding at least one material selected from the group consisting of fiber reinforced plastics, glass and ceramics with modified polyphenylene ether with high strength, a method for producing the same, and the material and modified polyphenylene ether. The present invention relates to a joined body formed by joining and a method for manufacturing the same.

In the electronic device industry and the automobile industry, the evolution of technology is progressing further, and the needs for materials are diversifying and becoming more sophisticated. In order to maximize the performance of a product and realize multiple functions at the same time, a multi-material structure in which different materials (hereinafter, different materials) are arranged in the right place is indispensable. The multi-material structure is formed by joining dissimilar materials, and various joining techniques such as melt welding and bonding are being studied as the joining means.
Regarding the multi-material structure, for example, in smartphones, the entire surface is vitrified, and a technique for joining glass and a highly transparent resin such as polycarbonate by insert molding or the like is required.

As a method for joining glass and resin, the engineering plastic is melt-bonded to the glass by applying an adhesive force improving agent to the glass to the pellet-shaped engineering plastic and then heating and melting the engineering plastic in contact with the glass. (Patent Document 1) is disclosed. In automobiles, there are scenes where FRP (fiber reinforced plastic) and resin are joined, and a technique for firmly joining FRP and resin is required. In power equipment, insulators such as insulating containers made of ceramic as an insert material and molded with resin are often used, and a technique for firmly joining ceramic and resin is required.

Conventionally, when dissimilar materials are directly bonded to each other, there is a problem that stress is concentrated on the interface due to the difference in heat shrinkage between the materials, which causes cracks and peeling.
In relation to this problem, in the resin mold structure of the insulating container, a technique for preventing the occurrence of cracks at the internal interface of the resin mold structure by applying a silane coupling agent between the ceramic and the resin to perform interfacial treatment has been developed. It is disclosed (Non-Patent Document 1).

Ceramics used for the insulating container, in order to prevent contamination, it is often used in glazed vitreous _{_{_{(SiO 2 -10% Al 2 O}}} 3) on the surface thereof. Therefore, in the resin mold structure, the interface between the glaze and the resin on the ceramic surface is slippery.
In Non-Patent Document 1, paying attention to the above points, the adhesive strength of the internal interface of the resin mold structure is improved by the interface treatment with a silane coupling agent.

Japanese Unexamined Patent Publication No. 2006-297662

However, in the prior art, there is a problem that sufficient bonding strength cannot be realized between glass and resin in applications such as automobile parts and OA equipment.
Further, in the technique of Patent Document 1, it is necessary to reduce the upper limit of the injection pressure to about 60 MPa at the maximum as a measure against glass breakage during insert molding, and the problem that the injection pressure cannot be sufficiently increased and the demand for improvement of durability are met. There is a problem that it is difficult to respond. Further, the technique of Non-Patent Document 1 cannot solve the problem that stress is concentrated on the resin end of the interface due to the difference in heat shrinkage between the materials, and it is difficult to further improve the joint strength and durability.

The present invention has been made in view of such technical background, and is used for bonding modified polyphenylene ether with at least one material selected from the group consisting of fiber reinforced plastics, glass and ceramics with high strength.
