Title:
METAL/RESIN COMPOSITE STRUCTURE, AND MANUFACTURING METHOD OF METAL/RESIN COMPOSITE STRUCTURE
Document Type and Number:
Japanese Patent JP2019018547
Kind Code:
A
Abstract:
To stably provide a metal/resin composite structure excellent in bond strength between a metal member and a resin member, even when melting viscosity of a thermoplastic resin is high and fluidity is inferior during melting.SOLUTION: There is provided a metal/resin composite structure 106 having a metal member 103 with a fine uneven surface 104, and a resin member 105 bound to the fine uneven surface 104 of the metal member 103, and constituted by a thermoplastic resin or a resin composition containing the thermoplastic resin, in which surface roughnesses of total 6 linear parts of any 3 linear parts in parallel relationship and any 3 linear part orthogonal to the 3 linear part on the fine uneven surface 104 of the metal member 103 satisfy a requirement (1) and a requirement (2) at same time, and a surface of the fine uneven surface 104 includes a dendritic layer. (1) average of ten points average roughness (Rz) is over 5 μm. (2) average value of average lengths (RSm) of roughness curve elements is in a range of 10 to 400 μm.SELECTED DRAWING: Figure 1
