METHOD OF MANUFACTURING LAMINATED STRUCTURE

摘要

A laminated structure is manufactured using a mold in which an injection port is provided, the laminated structure including a core layer, a first surface layer, and a second surface layer. The mold includes a first surface layer material conveyance path through which a raw material of the first surface layer is conveyed, a second surface layer material conveyance path through which a raw material of the second surface layer is conveyed, and a core layer material conveyance path through which a raw material of the core layer is conveyed. The paths merge at the injection port. The mold has a shape in which a downstream portion downstream of a merging location that is the injection port does not contact the injected laminated structure formed of the raw materials. The laminated structure is injected by causing viscous fluids as the raw materials into the paths, respectively.

1. A method of manufacturing a laminated structure comprising
manufacturing the laminated structure with use of a mold in which an injection port is provided, through injection of raw materials from the injection port, the laminated structure including a core layer, a first surface layer that is stacked on one surface of the core layer, and a second surface layer that is stacked on another surface of the core layer, wherein: the mold includes a first surface layer material conveyance path through which the raw material of the first surface layer is conveyed toward the injection port, a second surface layer material conveyance path through which the raw material of the second surface layer is conveyed toward the injection port, and a core layer material conveyance path through which the raw material of the core layer is conveyed toward the injection port, the core layer material conveyance path being provided between the first surface layer material conveyance path and the second surface layer material conveyance path; the core layer material conveyance path, the first surface layer material conveyance path and the second surface layer material conveyance path merge at the injection port; the mold has a shape in which a downstream portion does not contact the injected laminated structure formed of the raw materials, the downstream portion being downstream of a merging location that is the injection port, with respect to flow of the raw materials; and the laminated structure in which the raw material of the first surface layer, the raw material of the core layer, and the raw material of the second surface layer are stacked in a layered manner is injected from the injection port by causing a viscous fluid as the raw material of the first surface layer, a viscous fluid as the raw material of the second surface layer, and a viscous fluid as the raw material of the core layer to flow into the first surface layer material conveyance path, the second surface layer material conveyance path, and the core layer material conveyance path, respectively.
