PURPOSE:To readily braid a braided structural matter useful for a FRP core material, etc., having high strength and a shape of abundant variations capable of suitably changing braiding density by varying pulling up or pulling down speed of a braided structural matter in a braiding process with time. CONSTITUTION:In a solid braiding machine, braiding is performed by running of plural bobbin carriers 2 in crossing to counterclockwise or clockwise along an annular orbit 1 formed on a disk. Fiber bundles F drawn out from every bobbins fitted on respective bobbin carriers 2 are braided on a mandrel 3 located over a central part of the annular orbit 1 and upwardly pulled up to obtain a braided matter. In said process, a ratio of moving speed of the bobbin carriers to pulling up or pulling down speed of the mandrel 3 is changed with time to braid a braided structural matter having different running angles of fiber bundles. |
