[0133] The thermoplastic resins recorded in Table 1 or Table 2 and the fillers recorded in Table 1 or Table 2 are melt-extruded according to the amount recorded in Table 1 or Table 2 by a twin-screw extruder with a 30 mm φ screw to obtain pellets (resin combination). The extrusion temperature at the time of melt extrusion is 280°C for polyamide resin, 350°C for thermoplastic polyimide resin, and 290°C for polycarbonate resin.

[0134] The processing of the concavo-convex portion of the metal layer is performed as follows.

[0135] An aluminum alloy sheet (A5052) was cut into 60×60×2 (mm). In a tank, the aluminum alloy sheet was immersed in an aqueous solution containing 7.5% by volume of aluminum degreasing agent "NE-6 (manufactured by Meltex Corporation)" at 60° C. for 5 minutes, and washed with distilled water. Next, an aqueous hydrochloric acid solution having a concentration of 1 mass % at 40° C. was prepared in another tank, and the degreased aluminum alloy sheet was im...

Abstract

Provided are: a multilayer body having good adhesion between a metal layer and a resin layer containing nanofibers or the like; and a method for producing the multilayer body. The multilayer body comprises: a metal layer having a recess-and-protrusion region in which an average length (RSm) of a contour curve element is 0.5-10 [mu]m; and a resin layer in contact with the recess-and-protrusion region of the metal layer, wherein the resin layer includes a thermoplastic resin and fibrous fillers, the number average fiber diameter (F) of the fibrous fillers is less than 1 [mu]m, and the ratio of the average length (RSm) of the contour curve element in the recess-and-protrusion region to the number average fiber diameter (F) of the fibrous fillers is 1-20000.

Description

technical field [0001] The present invention relates to a multilayer body of a resin layer and a metal layer and a method for manufacturing the multilayer body. Background technique [0002] There is a technique for increasing the strength and rigidity of a resin layer by including reinforcing fibers in a thermoplastic resin. Such resin molded products are called fiber-reinforced plastics (Fiber-Reinforced Plastics), etc., and can be used in many aspects from construction materials, automobile parts, stationery, household goods to semiconductor-related parts. [0003] On the other hand, a resin layer reinforced with such fibers is sometimes bonded to a metal layer. In general, the materials of the resin layer and the metal layer may differ greatly, making it difficult to ensure adhesion, and research and development have been conducted to improve this. [0004] For example, Patent Document 1 discloses a multilayer body having a metal layer and a carbon fiber-reinforced pol...
