3D 3D profiled beam preforms in which the thickness direction fibers are continuously reinforced and a method for manufacturing the same

摘要

An integrated flat preform part having one orthogonal bonding layer through which fibers in the thickness direction pass through the entire thickness of the preform; And a separable flat plate preform part having a plurality of orthogonal bonding layers in contact with the integrated flat plate preform part and a fiber in a thickness direction penetrating a part of the thickness of the preform. The semi-structured profile beam preform provided in one aspect of the present invention is manufactured by an orthogonal bonding method to minimize the spacing between warp and weft, thereby having a compact configuration.
