To provide a core for a laminate which has a primer layer or an adhesive layer of a uniform thickness formed on the surface and shows high adhesive properties with a skin material, and a method for manufacturing the core.
The core for a laminate comprises a thermoplastic resin film, with a primer layer formed on its one side, which is lapped on one side of a nonwoven fabric consisting of an inorganic fiber in such a way that the primer layer faces outward and then melted, so that the interstices of the fibers are impregnated with the film resins, leaving the primer layer intact on one side of the nonwoven fabric and consequently, the fibers are mutually joined together with the formation of the primer layer on one side of the nonwoven fabric. In addition, an adhesive layer of a reaction curing type is formed on the primer layer and at least one side of the skin material to be bonded on the primer layer and the core material for the laminate and the skin material are bonded together through the adhesive layer to obtain the laminate for molding.
