<p><P>PROBLEM TO BE SOLVED: To easily manufacture a honeycomb-like structure having various cell part shapes. <P>SOLUTION: A preform is formed by coating a core body with a prepreg to laminate (S1-S3). The preform is heated at temperatures in which the core body is not thermally shrunk, the prepreg is preliminarily hardened to be half-hardened, and at the same time, the prepregs abutting mutually self-adhere (S5). The heating of the preform at the temperatures in which the core body is thermally shrunk definitively hardens the prepregs and at the same time, thermally shrinks the core body (S6). That is, the prepreg is not deformed and is constituted as a cell wall, and at the same time, a space formed by the thermal shrinkage of the core body is constituted as a cell hole, by which the cell part is formed by shaping the cell part so as to turn a desired shape depending on the core body shape, and the process of expanding the preform or securing a peelability of the expanded part becomes unnecessary. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
