Abstract
A method for manufacturing a composite member, in which a composite member having a high joining strength can be manufactured in an inexpensive and efficient way; and the composite member. A metal member and a resin-containing member are joined together by heating the metal member while pressing the resin-containing member against a metal porous film formed on a surface of the metal member. The porous film is formed by impacting the surface of the metal member with metal powder by the cold spray process.
Claims14
A composite member, comprising:
- a metal member,
- a porous film formed directly on a surface of the metal member, and
- a resin-containing member provided on the porous film in a side opposite to the metal member,
- wherein the porous film has a porosity of 4% or more and a film thickness of 25 μm or more and 280 μm or less, and
- wherein the metal member and the resin-containing member are joined together by allowing a portion of the resin-containing member to enter into voids of the porous film.
