Abstract: A plate-like molded body has a concavo-convex shape having intaglio portions and raised portions and has pores formed therein. The plate-like molded body has uniform mechanical properties. A method for manufacturing a plate-like molded body includes a molding step of placing a raw fabric including a resin component and a filler component on intaglios of a mold, and the intaglios correspond to a concavo-convex shape. The method additionally includes suctioning the raw fabric at a bottom of the mold.

Abstract: A molded body has a concavo-convex shape with intaglio portions and raised portions and has uniform physical properties in the intaglio portions and the raised portions. A method for manufacturing the plate-like molded body includes a molding step of placing a raw fabric including a resin component and a filler component on intaglios of a mold, and the intaglios correspond to the concavo-convex shape. The method also includes applying pressure at a top of the raw fabric while suctioning the raw fabric at a bottom of the mold.

Abstract: A strength prediction system for a multilayer material with n films stacked includes an input portion where one or more values are entered. The values include the elastic modulus of each layer, Poisson's ratio, Young's modulus, thickness, stacking angle, principal stress direction strength, and the total thickness of the multilayer material. The strength prediction system also includes a control portion that calculates the strength of a multilayer material by applying the values entered in the input portion, a display connected to the control portion, and a storage portion connected to the control portion. The control portion defines a strength value of a multilayer material. A method for predicting the strength of a multilayer material having two or more films stacked thereto is also provided.

Abstract: A system and method for predicting physical properties such as elastic moduli, shear moduli, and Poisson's ratios (Poisson's ratio) of an entire laminate are provided. The system and method can determine not only homogenized stiffness of the entire laminate of the multilayer material but also physical property values or a thickness of an undetermined layer, when developing a multilayer material having a laminated structure.

Abstract: A system and method for predicting the physical properties of a multilayer material are provided. The system and method can predict physical properties such as a coefficient of thermal expansion and coefficient of water expansion of the multilayer material, and a warpage of the multilayer material when developing the multilayer material.

Abstract: The present technology relates to a system and method for predicting the physical properties of a multilayer material, and the system and method may predict physical properties such as the elastic modulus, shear modulus, and Poisson's ratio of an entire laminate when a multilayer material having a laminated structure is developed, and may predict not only the homogenized robustness of the entire laminate of the multilayer material, but also the stress and strain of each layer at the time of occurrence of external forces including expansion stress considering environmental factors such as a temperature change or a humidity change are generated.
