Patent ID: 8518521

Claim:
A composite molded article, comprising: a metal member using metal as a base material and having a surface; and a fiber-reinforced polymer material portion coated on at least part of the surface of the metal member and having a polymer material as a matrix and a plurality of reinforcing fibers for reinforcing the matrix; the surface of the metal member having a plurality of projections juxtaposed regularly or randomly at a pitch distance greater than diameters of the reinforcing fibers and the respective facing projections forming enterable spaces which part of the polymer material constituting the fiber-reinforced polymer material portion enters and at least part of the reinforcing fibers can enter, the pitch distance being within a range of 30 to 2000 μm, and the projections being connected with each other in a plan view taken in a perpendicular direction to the surface of the metal member, and a depth of the enterable spaces is set to be the pitch distance times a range of 0.7 to 1.7.
