 * Not to be confused with the Swedish musician Leif Asp

Leif Erik Asp, born on the 9th of March 1966 in Storfors, Sweden, is a Swedish mechanical engineer and material scientist. He is a professor in composite mechanics at Chalmers University of Technology, Sweden, and is now leading research in lightweight composite materials and structures, with a large focus on structural batteries since 2015.

Education
During his time at upper secondary school, Leif Asp studied a technical education with a specialization in chemistry at Älvkulle upper secondary school in Karlstad. After which he acquired a civil engineer degree in mechanical engineering in the year of 1991 at Luleå University of Technology. Followed by a PhD in polymer engineering, 1995. Head supervisor for his PhD thesis,"Transverse failure initiation in polymer composites" was professor Lars Berglund. The thesis concerned modelling of initiation of transverse crack in unidirectional composites.

Career
Leif Asp has had a long career at Swedish research institutes since before he was required to Chalmers University of Technology in August of 1995. During the period December 1095 to July 2000, he worked at the Structures department at the Aeronautical Research Institute of Sweden, in Bromma. Then he joined SICOMP, the Swedish Institute of Composites, where he founded their Mölndal office. In 2011, Asp was appointed Head of Research at Swerea SICOMP. He stayed in this position until he left for Chalmers university of technology, where he joined as full professor in August 2015. During his time at SICOMP he was appointed Associate professor (2001) and Adjunct professor (2004) at Luleå University of Technology, and Adjunct professor at Chalmers university of technology (2011). In April 2024, Asp joined as a member of the board of Chalmers university of technology.

Leif Asp is editor for the journal Composites Science and Technology. During the period 2018 to 2024 he has had the role as co-director for the Area of Advance Materials Science at Chalmers. He has also been the President of the International Committteeon Composite Materialsr (ICCM)an the European Society for Composite Materials r.

Research
Professor Asp’s research is focused on efficient design methodologies for carbon fibre composite transport applications. The research relies on more than twenty-five years’ experience in damage tolerance modelling, design and certification methods for aircraft composite structures. Composite design and verification rely 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 across the transport sector, e.g. automotive, aero engines and aircraft structures.

Since 2007, Professor Asp leads research activities on multifunctional composites. In particular, the research group performs research on structural battery composites, a material that can simultaneously store electrical energy and carry mechanical loads. The work comprises material development and characterization, ranging from mechanical and electrochemical characterization of constituents to cells and multi-cell structures.
