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.
Claims20
A plate-like molded body comprising:
- a resin component and a filler component,
- wherein a concavo-convex shape including raised portions and intaglio portions is formed on the plate-like molded body, and
- wherein a difference in tensile rupture strength between the raised portions and the intaglio portions has an absolute value of 10% or less, and
- wherein the tensile rupture strength of the intaglio portions is 50 MPa or more, or a change rate of the tensile rupture strength compared to a raw fabric is 80% or more.
A plate-like molded body comprising:
- a resin component;
- a filler component;
- and
- sides formed in a first direction,
- wherein
- a concavo-convex shape including raised portions and intaglio portions is formed on the plate-like molded body,
- and
- wherein a tensile rupture strength in each of an upper, a middle, and a lower ends obtained by trisecting the plate-like molded body in a direction perpendicular to the side in the first direction, and wherein the tensile rupture strength has standard deviation of 100 or less.
A method for manufacturing a plate-like molded body comprising:
- a molding step of placing a raw fabric including a resin component and a filler component on intaglios of a mold, the intaglios correspond to the concavo-convex shape, and
- applying a pressure at a top of the raw fabric while suctioning the raw fabric at a bottom of the mold,
- wherein the plate-like molded body has a concavo-convex shape including raised portions and intaglio portions.
