む。When the powdery or liquid foamable phenol resin initial condensate is applied to the surface of the cardboard and hot pressed to form the cardboard into a predetermined shape, the foamable phenolic resin precondensate foams and becomes a resin. Although it hardens to form a phenol resin foam, even if cracks, wrinkles, etc. occur on the cardboard surface during the above-mentioned molding process, the phenol resin initial condensation product that foams and becomes a resin during the formation process of the phenol resin foam Cracks fill and wrinkles are absorbed. And the phenol resin foam formed on the cardboard surface has flame resistance and heat resistance,
In addition, since it contains air inside, it is rich in heat insulation and sound absorption.

貼着する。EXAMPLES The present invention will be described with reference to one example shown in FIGS. 1 to 4. The laminated material molded product (10) comprises a cardboard (1) and a phenol resin formed on the surface of the cardboard (1). It consists of a foam (2). The laminated material molded product (10) is molded into a ceiling shape as shown in FIG. 2, for example, and is used as a base material (11) for a molded ceiling of an automobile. In this case, as shown in FIG. 3, a surface covering material (3) made of a fiber non-woven fabric, a fiber knitted fabric, artificial leather or the like is further attached to the surface of the phenol resin foam (2).

を前段キュアーしてシート化しておいてもよい。In order to produce the laminated material molded product (10) of the present invention, the surface of the cardboard (1) is coated with the powder or liquid of the foamable phenol resin initial condensate, and the cardboard (1) is predetermined by hot pressing. Shape to shape. At this time, the foamable phenol resin initial condensate foams and becomes a resin to be cured. The corrugated cardboard before the hot pressing
The expandable phenol resin initial condensate applied to the surface of (1) may be cured in the previous stage to form a sheet.

面には発現しない。When cracks, wrinkles, etc. occur on the surface of the cardboard (1) in the above-mentioned molding process, the phenol resin precondensate, which is foamed and resinified, fills the cracks and absorbs wrinkles. The surface of the obtained phenol resin foam becomes smooth. For example, as shown in FIG. 4, even if wrinkles (1A) are generated on the surface of the cardboard (1), the wrinkles (1A) are absorbed by the layer thickness of the phenol resin foam (2) and do not appear on the surface.
