A method is provided for manufacturing a polyimide fiber paper intermediate structure, which includes: a short fiber preparing step for preparing shaved short fibers of a non-thermoplastic polyimide; and an intermediate structure forming step for forming a polyimide fiber paper intermediate structure in which the short fibers are temporarily bonded using a water-soluble and/or water-insoluble thermoplastic polymer having a melting point lower than a glass transition point of a polyimide.

Polyimide fiber paper using thermoplastic polymer

A polyimide fiber paper-manufacturing method is provided that includes a short fiber-preparing step in which shaved short fibers of a non-thermoplastic polyimide are prepared, and a provisionally-bonded paper-forming step in which the short fibers are mixed with water-soluble polymers which are a material having a decomposition temperature lower than a glass transition point of polyimide, and subjected to wet-papermaking to form provisionally-bonded paper.

Polyimide fiber sheet

A polyimide film F is brought into an intimate contact with a molding die having a concave molding surface so as to tightly close the open end thereof, and the polyimide film F is bent to deform only by the pressure difference of gas while being heated in a contactless manner. Molding is conducted by applying depressurization for a space on the side of the molding die relative to the polyimide film F while pressurizing the space on the opposite side for the pressure difference at least in the final stage of the bending deformation so as to be in intimate contact with the concave molding surface
