Title:
LAMINATE MOLDED MATERIAL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/119633
Kind Code:
A1
Abstract:
[Problem] To suppress the occurrence of positional deviation in a sliding direction of respective surfaces in a laminate molded material. [Solution] This laminate molded material is obtained by laminating at least two sheets that are plastically deformable, wherein the outer surfaces of the front and back layers are flat, and on the inner surfaces of the front and back layers, or on one or both of the opposing inner surfaces of the front and back layers and one or both of the front and back surfaces of a layer sandwiched between said front and back layers, a wavy section for allowing the surfaces to engage in the sliding direction is formed. [Effect] The wavy section is formed during molding; therefore, no processing is required before or after plastic deformation, there are few restrictions on the molded shape, productivity can be improved, and manufacturing costs can be reduced.
