Abstract

Official abstract text for this publication.

Provided is a method for producing a composite member formed by bonding a base material and a resin member. The method includes: a surface treatment step of forming micro-order or nano-order asperities on a surface of a base material; and a bonding step of directly bonding, by injection molding, a resin member to the surface of the base material that has the asperities formed in the surface treatment step. In addition, the composite member includes: a base material having micro-order or nano-order asperities on a surface thereof; and a resin member that is in direct contact with the surface of the base material.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a composite member formed by bonding a base material and a resin member, the method comprising: a surface treatment step of forming micro-order or nano-order asperities on a surface of the base material; and a bonding step of directly bonding, by injection molding, a resin member to the surface of the base material that has the asperities formed in the surface treatment step, wherein an arithmetic average inclination of the surface of the base material that has the asperities formed in the surface treatment step is 0.17 to 0.50. 2. The method according to claim 1 , wherein a root-mean-square inclination of the surface of the base material that has the asperities formed in the surface treatment step is 0.27 to 0.60. 3. The method according to claim 2 , wherein a material of the base material is a metal, glass, ceramic, or a resin. 4. The method according to claim 2 , wherein the surface treatment step is a step of forming the asperities using blast machining. 5. The method according to claim 1 , wherein the surface treatment step is a step of forming the asperities using blast machining. 6. The method according to claim 5 , wherein an injection pressure in the blast machining is 0.5 to 2.0 MPa. 7. The method according to claim 6 , wherein a particle size of blasting abrasives in the blast machining is 30 to 300 μm. 8. The method according to claim 6 , wherein a material of the base material is a metal, glass, ceramic, or a resin. 9. The method according to claim 5 , wherein a particle size of blasting abrasives in the blast machining is 30 to 300 μm. 10. The method according to claim 9 , wherein a material of the base material is a metal, glass, ceramic, or a resin. 11. The method according to claim 5 , wherein a material of the base material is a metal, glass, ceramic, or a resin. 12. The method according to claim 1 , wherein a material of the base material is a metal, glass, ceramic, or a resin.
