Abstract:
1. A method for producing a composite member having a metal member and a resin member, the method comprising the steps of: a) providing a resin composition comprising (i) thermoplastic resin having a resin melting point and/or a glass transition, and a solidification point; and (ii) a plurality of metal particles having one or more metal melting points between about 130° C. and 400° C.; b) disposing one or more metal member(s) in a mold cavity, each said metal member(s) having at least one exposed surface, and said mold cavity, optionally, having at least one mold cavity exposed surface; c) heating the one or more metal member(s) to a temperature equal or higher than at least one of the melting points of the plurality of metal particles to provide one or more heated metal member(s); d) heating the resin composition to a temperature higher than the resin melting point and higher than one or more metal melting points to provide a heated resin; e) injecting the heated resin into the mold to contact each heated metal member(s) exposed surface to provide a heated composite member; f) cooling said heated composite member below the resin solidification point; and g) removing the composite member from the mold cavity; to provide said composite member having an interfacial junction strength between said metal member(s) and said resin member of at least 3 MPa.
