Abstract
Official abstract text for this publication.
A method for manufacturing a lightweight cowl crossbar includes: producing an inner pipe, laminating a plurality of composite material layers wound around the inner pipe, and extruding an outer pipe on the winding layer, in which the plurality of composite material layers adjacent to each other are wound in different directions.
First claim
Opening claim text (preview).
What is claimed is: 1. A lightweight cowl crossbar comprising: an inner pipe located inside a cowl crossbeam; a winding layer formed along an outer surface of the inner pipe, wherein an uneven section of the winding layer is planarized using a drawing machine; and an outer pipe located on an upper surface of the winding layer, wherein the cowl crossbeam includes; a first cowl crossbeam and a second cowl crossbeam, a support leg located on the second cowl crossbeam, and a drawing block part including an absorption member and configured to surround the outer pipe of the first cowl crossbeam in a region where the first cowl crossbeam and the second cowl crossbeam overlap each other, wherein the support leg is configured to be fastened to the first cowl crossbeam integrally with the second cowl crossbeam, and one surface of the support leg includes a hollow part, and wherein the absorption member has a hollow shape corresponding to the hollow part. 2. The lightweight cowl crossbar of claim 1 , wherein the winding layer is made of a single-oriented fiber composite material. 3. The lightweight cowl crossbar of claim 1 , wherein the winding layer is made of at least two single-oriented fibers having different angles. 4. The lightweight cowl crossbar of claim 1 , wherein the outer pipe is configured to have a sawtooth shape. 5. The lightweight cowl crossbar of claim 1 , wherein at least a part of the outer surface of the cowl crossbeam comprises a flat region.
