Zusammenfassung:PROBLEM TO BE SOLVED: To inexpensively provide fiber formed product for carbon composite material reinforced by carbon fibers of excellent quality that can be integrally formed in a prescribed thickness without delamination via simple process in no need of the impregnation of the matrix material and the lamination of thin molded products. SOLUTION: Carbon fibers and the powdery matrix material are blown from the Venturi tube 1 together with the air flow into the fiber-loosening and mixing chamber to loosen carbon fibers and mix with the matrix material and the air flow containing the mixture is introduced into the fiber collecting chamber to deposit the loosened fiber mixture on the flat mesh fiber collector 21. Then, the piled-up loosened fiber mixture A is hot-pressed to give the objective formed fiber material.
