SPP1712 – Intrinsic hybrid composites for lightweight structures – Principles of manufacturing, characterisation and dimensioning
Development of the theoretical and technological principles for intrinsic thermoplastic-metal hollow structures with load-optimised multiscale form closure
Hybrid metal-composite with hierarchical interface structure.
In contrast to conventional forming processes as adhesive and riveted technologies, approaches with a mechanical interlock between a metal element and fibre-reinforced polymers (FRP) are rarely investigated. A material- and production-oriented design of intrinsic hybrids is the basis for the development of innovative lightweight joints with a mixed-architecture. A mechanical interlock allows the application of extreme loads into rod-shaped and tubular FRP structures, for instance pressure tanks, axis structures, shaft drives and tensile bars. Contour joints are particularly suitable for carrying longitudinal forces and bending moments. Though, specifications for those joint technologies are still missing. The objective of subproject 5 within the Priority Programme (SPP) 1712 is therefore the development of the theoretical and technological principles for intrinsic thermoplastic-metal hollow structures with load-optimised multiscale form closure. At the Chair for Computational and Experimental Solid Mechanics the following scopes are investigated:
- Modelling and simulation of the hierarchical material and interface structure of hybrid composites
- Development of multiscale homogenisation methods for characterisation of effective interface properties
- Modelling of damage and failure behaviour of the FRP material and different interface profiles
- Implementation and parametrisation of macroscopic cohesive zone models with properties extracted from microscale simulations
