Reinforcing material for the local reinforcement of a component formed with a composite material, and method

摘要

Disclosed is a reinforcing material for the local reinforcement of a component formed with a composite material, in particular in areas of force introduction and/or connecting areas. The reinforcing material is formed by a metallic sheet-like formation, the metallic sheet-like formation having a surface with increased roughness to improve adhesion and a coating applied to the surface to provide a seal and improve the bond with the composite material. As a result of the presence of a coating on the metallic sheet-like formation, once it has been rolled up on supply rolls, said sheet-like formation can be drawn off from the supply rolls and at the same time processed in an automated manner by means of known computer-controlled laying devices with CRP prepreg materials in web form by laying layer by layer to produce components, in particular of large format, for aircraft. The reinforcing material thereby ensures a high embedding strength in the case of introduced boreholes or the like, in particular in areas of force introduction and/or connecting areas. Also disclosed is a method for producing a reinforcing material. In addition, the invention relates to a method for producing components, in particular components of large format for aircraft, with the composite material and with the reinforcing material.

主权项

1. A reinforcing material for the local reinforcement of a layered component formed with
a carbon fiber reinforced plastic (CRP) prepreg material and a curable synthetic resin as a resin matrix, the reinforcing material further comprising: a surface roughened metallic sheet-like form, and an adhesive coating of a curable synthetic resin capable of sealing the roughened surface of the metal foil, wherein the metal foil surface comprises roughness on the microscopic scale, formed by at least one of a grinding, etching, coating, and plasma treatment, wherein said adhesive coating comprises the same curable synthetic resin used to form a resin matrix in the CRP prepreg material, wherein said adhesive coating provides tacking of the reinforcing material to the layered component, and wherein the metallic sheet-like form has a substantially web-like form.
