Numerical Analysis of Thermoplastically Welded CFRP Structures

Abstract Carbon fibre reinforced thermoplastic polymers (CFRTP) are of particular interest to the aerospace industry. The possibility welding as a joining method makes CFRTP an enabler in pre-installation systemic functionalities and cabin elements. This can be achieved by dust-free joining. In this work, thermoplastically welded zones numerically analysed evaluated for their failure behaviour. Finite element models evaluation peel strength (L-pull) defined. particular, respective beginning damage well propagation within zone order identify critical regions derive possibilities design improvements.
