Abstract
Official abstract text for this publication.
An impact beam structure of a CFRP door for a vehicle is disclosed. A outer impact beam and an inner impact beam are separately molded and then coupled to each other such that an impact beam is formed. The impact beam is coupled to an inner panel of the CFRP door for the vehicle.
First claim
Opening claim text (preview).
What is claimed is: 1. An impact beam structure of a door for a vehicle, wherein the impact beam structure formed by separately molding an outer impact beam made of carbon fiber reinforced plastics (CFRP) and an inner impact beam made of CFRP and coupling the outer impact beam and the inner impact beam to each other, the impact beam structure to be coupled to an inner panel of the vehicle door, wherein the outer impact beam and the inner impact beam each comprises two closed cross sections and a connection flange that connects the two closed cross sections and wherein the two closed cross sections and the connection flange of the outer impact beam are arranged to be respectively overlapped with the two closed cross sections and the connection flange of the inner impact beam. 2. The impact beam structure of claim 1 , wherein the inner panel is made of a CFRP material. 3. The impact beam structure of claim 1 , wherein the inner impact beam is roll-forming molded. 4. The impact beam structure of claim 1 , wherein the closed cross sections have quadrangular box shapes. 5. The impact beam structure of claim 1 , wherein the connection flange of the outer impact beam and the connection flange of the inner impact beam are bonded to each other by spot welding. 6. The impact beam structure of claim 1 , wherein the inner panel comprises a stepped portion and a side surface, wherein a front end of the outer impact beam is laid on the stepped portion and bonded thereto by an adhesive, and wherein a front end of the inner impact beam is bonded to the side surface by the adhesive. 7. The impact beam structure of claim 1 , wherein the inner panel comprises a stepped portion and an inner surface that faces inside a cabin, wherein a front end of the outer impact beam is laid on the stepped portion and then bonded thereto by an adhesive, and wherein a front end of the inner impact beam is bonded to the inner surface by the adhesive.
