<P>PROBLEM TO BE SOLVED: To provide a sandwich molding capable of preventing deterioration in mechanical strength even under a high temperature environment. <P>SOLUTION: In the sandwich molding, a skin sandwiching a core is formed on a surface of the core. A polyamide resin composition (A) constituting the skin has a mixing ratio (a/x) between a polyamide resin (a) and a glass fiber (x) of 45/55 to 70/30 in a mass ratio. A polyamide resin composition (B) constituting the core has a mixing ratio (b/y) between a polyamide resin (b) and a glass fiber (y) of 35/65 to 55/45 in a mass ratio. The melt viscosity ηa, ηb of the polyamide resin composition (A) and the polyamide resin composition (B) measured under a prescribed condition is 1<logηa/logηb<1.4. A relationship between a content X of the glass fiber (x) in the polyamide resin composition (A) and a content Y of the glass fiber (y) in the polyamide resin composition (B) is X≤Y. <P>COPYRIGHT: (C)2013,JPO&INPIT |
