Abstrakt: Elastomer-fiber reinforced plastic hybrid materials (E-FRP) provide potential for many future lightweight applications. Suspension and powertrain components in hybrid design can be optimized in terms of stress absorption by using elastomer interlayers to decouple the highly stressed fiber composite areas. First prototype runs with hybrid drive shafts have demonstrated a significantly increased mechanical performance compared to conventional composite structures. However, the material properties have not been sufficiently verified for use in the targeted application fields at this stage of development. To increase the technology readiness level of the E-FRP material, systematic experimental testing is necessary for the qualification of materials and production processes. In this study, a procedure for characterizing the material properties for the elastomeric interlayers is presented. First, the maximum principal stresses occurring in the application are determined via finite element simulations. A subsequent material characterization under dynamic loading is carried out for 2 elastomeric polyurethane hot cast systems. The usability of the hysteresis measurement method is demonstrated and characteristic values are determined and evaluated. An outlook on further application of the method is given and relevant material parameters for the selection of suitable materials are discussed. [ABSTRACT FROM AUTHOR]
