Leif Asp

Full Professor at Chalmers, Industrial and Materials Science, Material and Computational Mechanics

Leif Asp, Professor in Lightweight composite materials and structures at Department of Industrial and Materials Science, Chalmers. Leif’s research is focused on efficient design methodologies for carbon fibre composite automotive applications. The research relies on more than twenty years’ experience in damage tolerance modelling, design and certification methods for aircraft composite structures. A switch from traditional metal car components and BIW to cars made from composites will require modifications to the design practice used today. Composite design and verification relies on combined virtual and experimental approaches in a so-called building block approach. The experimental test campaign required to complete and verify a composite vehicle is costly. The research in Lightweight composites materials and structures aims to increase analysis capability to allow increased virtual testing, and hence reduce cost related to physical testing. The research will address a wide range of carbon fibre composites, from traditional UD-composites via textile reinforced to short fibre composites, and as such will be relevant for applications outside the automotive sector, e.g. for aero engines and aircraft structures.
