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.
