In certain embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, a utility cabinet, and a flatbed. In other embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, and a flatbed. In some embodiments, the front cage at least partially defines an operator cabin, the rear floor is positioned rearward of the front cage in a longitudinal direction, and the intermediate section is disposed at least partially between the front cage and the rear floor in the longitudinal direction.

A blow mold method for a double-walled container, including: blowing in which an intermediate molded article is molded by stretch blowing a preform housed in a die; and pressing in which the intermediate molded article is pressed inside the die and a double-walled container is molded. During the pressing, an internal floor-corresponding section is pressed such that internal wall-corresponding section is inverted as far as the inside of an outer wall-corresponding section, in a state in which heat retention is maintained such that the internal wall-corresponding section can be inverted as far as the inside of the outer wall-corresponding section.

Disclosed herein are methods for fabricating a composite structure by forming, via additive manufacturing, a solid-phase component; positioning the solid-phase component and a reinforcement into a mold cavity; and consolidating, in the mold cavity, the solid-phase component, the reinforcement, and a liquid-phase component to form the composite structure.

A method for manufacturing a fuel cell separator includes heating a sheet, pressing the sheet using a first die, thereby forming the sheet so as to have a predetermined thickness, cooling, together with the first die, the sheet that has been formed so as to have the predetermined thickness, and pressing the sheet that has undergone the cooling using a second die, thereby forming a gas passage in the sheet. In the sheet, a content of a thermoplastic resin is greater than or equal to 20 weight percent and less than or equal to 30 weight percent and a content of the carbon material particles is greater than or equal to 70 weight percent and less than or equal to 80 weight percent. The heating the sheet includes heating the sheet to a temperature that is higher than a melting point of the thermoplastic resin.

A method for manufacturing a composite structure having first and second structural members includes the steps of: (A) placing a plate in a forming mold having a first molding member, and a second molding member with an injection hole; (B) moving the first molding member toward the second molding member to stamp and deform the plate; (C) injecting a molten substrate onto the plate via the injection hole to stamp and deform again the plate so as to form the first structural member; (D) removing an assembly of the first structural member and a solidified substrate from the first molding member; and (E) removing an excess part of the solidified substrate to form the second structural member.
