Hybrid lightweight materials as an alternative with great potential
Fiber-reinforced polymers (FRP) have become essential for numerous applications, such as automotive and aerospace industries. However, not all components can be replaced only by FRP composites, as the materials often do not match the requirements for further processing or the later conditions of use. Hybrid components combine the advantages of lightweight FRP composites with those of metal materials. The key challenge is the force-transmitting joint of the FRP and the metal materials, which requires appropriate preparation of the components. This way, mechanically resilient lightweight components for lightweight constructions can be obtained.
To create microscopic undercuts, a structure is implemented into the metallic material with a laser beam. In the following thermal joining process, the created undercuts are filled with the FRP and build a form-fit connection. For maximum weight reduction, the metallic components can be reduced to a minimum thickness of 0.2 mm. Typical metallic materials for hybrid lightweight materials are primarily aluminum alloys and stainless steels. The shape and design of the structures can be individually adapted to the subsequent application.
