Embodiment 1

[0067] A PPS resin substrate (manufactured by Toray Corporation, model A900, 10 mm×10 mm×thickness 2 mm) on which a Pt nanocoil (a solid coil with a diameter of 250 nm and a coil pitch of 3.2 μm) was mounted was prepared as a sample of the example. The substrate is set on an electronic balance, and a Pt nanocoil is placed on the substrate. By this measurement, it was confirmed that the weighing was not more than the lower limit (0.1 mg). Therefore, the amount of Pt nanocoils on the substrate is 0.1 mg / cm 2 the following.

[0068] As a sample of a comparative example, a mixture of 60% by weight (1.3g / cm 3 ) NiZn ferrite (manufactured by JFE Chemical Co., Ltd., model JN-350) and PPS resin (manufactured by Toray Corporation, model A900) were molded on a substrate of 10 mm×10 mm×thickness 2 mm. It should be noted that the ferrite material is a conventionally known material, and it is a material with high electromagnetic wave absorption efficiency.

Embodiment 2

[0074] As a sample, a polyether ether ketone (=PEEK) resin substrate (manufactured by Victrex Japan, model 450G, 10 mm x 10 mm x thickness) on which a Pt nanocoil (a solid coil with a diameter of 250 nm and a coil pitch of 3.2 μm) was prepared was prepared. 3mm).

[0075] Here, the loaded amount of nanomaterials is set to 7.2 μg / cm 2 , 12μg / cm 2 , 24μg / cm 2 .

[0076] As a sample of the comparative example, the same polyether ether ketone resin substrate as the above-mentioned example was prepared, and the Pt nanocoil was not mounted, and microwaves were irradiated from above the substrate in the same manner as in the above-mentioned example, and the substrate surface was measured using an infrared thermal imaging camera. Temporal changes in temperature. show the result in Figure 5 .

[0077] The surface temperature of the sample (PEEK resin substrate) on which no nanomaterial was loaded hardly rose. On the other hand, as the loading amount of the nanomaterial increase...

Abstract

Provided are an adhesive that makes it possible to bond thermoplastic resins to each other in a short time and to obtain excellent adhesive strength, a structure bonded by this adhesive, and a bonding method using this adhesive. The adhesive bonds a first member (11) containing a thermoplastic resin or a thermoplastic resin reinforced by carbon fibers and a second member (12) containing this thermoplastic resin or this thermoplastic resin reinforced by carbon fibers. The adhesive has a thermoplastic resin as the base material and contains a metallic nano material that generates heat by absorbing electromagnetic waves, in this base material.

Description

technical field [0001] The present invention relates to an adhesive, a structure using the adhesive, and a bonding method using the adhesive, and particularly relates to an adhesive for bonding thermoplastic resins together. Background technique [0002] Resins reinforced with carbon fibers (carbon fiber reinforced plastics) are lightweight, high-strength, and highly elastic materials. Carbon fiber reinforced plastics can be used in aircraft components, windmill wings, etc. Carbon fiber-reinforced plastics include a thermosetting resin-based component (carbon fiber-reinforced thermosetting resin plastic: CFRP) and a thermoplastic resin-based component (carbon fiber-reinforced thermoplastic resin plastic: CFRTP). Compared with CFRP, CFRTP has the advantage of shorter molding time (high cycle characteristics). [0003] For example, in aircraft components, there are sites where members made of CFRTP are joined, sites where members made of CFRTP and members made of thermoplast...
