Document Type and Number:
WIPO Patent Application WO/2017/110798
Kind Code:
A1
Abstract:
Provided is a method for producing a sheet core material 1 that is constructed with a foam molded substrate 2 and a frame member 3 embedded in the periphery thereof, the method comprising: step (a) for obtaining the foam molded substrate 2 by heating thermoplastic resin foam particles within a mold cavity in which the frame member 3 is disposed, so as to cause the foam particles to be fuse and bond to each other and cause the frame member 3 to be embedded in the periphery of the foam molded substrate; and step (b) for forming voids S, S' in the foam molded substrate 2 at adjacent positions along the frame member 3 either at the same time as step (a) or after step (a). The voids S, S' are formed in a size and a shape that allow relative movement between the frame member 3 and the foam molded substrate 2 when the foam molded substrate contracts after step (b).
