Abstract
To provide a multilayer body, containing a metal plate; and a prepreg adhered directly or indirectly to the metal plate in the plane direction, wherein the prepreg has continuous reinforcing fibers arranged parallelly in one direction impregnated with a polyamide resin, and contains 5 to 300 parts by mass of the continuous reinforcing fibers with respect to 100 parts by mass of the polyamide resin; and the metal plate has a tensile strength as measured according to JIS Z2241 of 300 MPa or higher and 1,400 MPa or lower.

A multilayer body, comprising:
- a metal plate;
- and a prepreg adhered directly or indirectly to the metal plate in the plane direction,
- wherein the prepreg has continuous reinforcing fibers arranged parallelly in one direction impregnated with a polyamide resin, and contains 5 to 300 parts by mass of the continuous reinforcing fibers with respect to 100 parts by mass of the polyamide resin;
- and the metal plate has a tensile strength as measured according to JIS Z2241 of 300 MPa or higher and 1,400 MPa or lower.
A method for producing a multilayer body comprising a metal plate and a prepreg welded to the metal plate in the plane direction,
- wherein the prepreg has continuous reinforcing fibers arranged parallelly in one direction impregnated with a polyamide resin;
- the prepreg contains 5 to 300 parts by mass of the continuous reinforcing fibers with respect to 100 parts by mass of the polyamide resin;
- and
- the metal plate has a tensile strength as measured according to JIS Z2241 of 300 MPa or higher and 1,400 MPa or lower,
- the method comprising laminating the metal plate, a xylylenediamine-based polyamide resin film and the prepreg so as to be contacted in this order, and further heating the resultant to weld the metal plate, the xylylenediamine-based polyamide resin film and the prepreg,
- wherein the xylylenediamine-based polyamide resin film comprises a polyamide resin containing a constitutional unit originated from diamines and a constitutional unit originated from dicarboxylic acids, wherein 70% by mol or more of the constitutional unit originated from diamines is originated from xylylenediamines, and 70% by mol or more of the constitutional unit originated from dicarboxylic acids is originated from α,ω-straight-chain aliphatic dicarboxylic acids having 4 to 20 carbon atoms.
A multilayer body,
- wherein a metal plate, a xylylenediamine-based polyamide resin film and a prepreg having continuous reinforcing fibers arranged parallelly in one direction impregnated with a polyamide resin are laminated so as to be contacted in this order;
- the metal plate has a tensile strength as measured according to JIS Z2241 of 300 M1 Pa or higher and 1,400 MPa or lower;
- and
- the xylylenediamine-based polyamide resin film comprises a polyamide resin containing a constitutional unit originated from diamines and a constitutional unit originated from dicarboxylic acids, wherein 70% by mol or more of the constitutional unit originated from diamines is originated from xylylenediamines, and 70% by mol or more of the constitutional unit originated from dicarboxylic acids is originated from α,ω-straight-chain aliphatic dicarboxylic acids having 4 to 20 carbon atoms.
