Expert in characterization of damaged composite materials for aerospace applications

I am a senior scientist at the Swedish Institute of Composites RISE SICOMP and guest lecturer (20%) at Linköping University, with 10 years of experience on research and development related to polymer composite materials. My area of expertise is characterization of mechanical properties and damage in lightweight composite structures using Destructive, Non-Destructive Testing methods (NDT) and Finite Element Method (FEM).

My work with composite materials has started with my master thesis where I studied micro-damage initiation and growth in laminated composites under thermo-mechanical loading using destructive testing. The continuation of that work was the subject of my PhD.

The years after graduating PhD studies have been very productive for me in terms of international networking and research collaboration. Apart from participation in conferences and workshops I have established an active collaboration with Small and Medium-sized Enterprises (SMEs), big companies, research institutes and Universities. I have been leading several national and European projects and working in close collaboration with SAAB and AIRBUS. In 2018-2019, for a duration of 14 months, I acted as group manager at RISE SICOMP. 

Since 2015, I have been involved at LiU. My role at LiU is not limited only to teaching composite but I have been very active in attracting external funds to restart the research activities in the area of composite materials. I have also supervised several master/bachelor theses and I am currently co-supervising two PhD students. 

In September 2019, I got my Docent degree in Engineering Materials from LiU. Since June 2020, I am a member of Innovative Materials Arena (IMA) Scientific Advisory Board in Linköping.

Researcher explains the behavior and structural integrity properties of advanced metal-composite airframe structures.

Improved analysis capability and strength properties of bolted joints in advanced metal-composite structure

The project is focused on the understanding of the behavior and structural integrity properties of advanced metal-composite airframe structures. The goal is to develop reliable and accurate methods and models that can predict the complex behavior of bolted hybrid structures and to find simplified models aiming to establish efficient methods for industrial applications. The project also includes development of methods and procedures to physically improve the strength of bolted joints.

Life and durability prediction of aero-engine composites (LUNA)

Increased use of polymeric composite materials in aero-engines opens up opportunities for the development of new light engine components with, in turn, the potential to reduce fuel consumption and thus the climate impact of aircraft. Such components will, during their lifetime, be subjected to combinations of mechanical and hygro-thermal load scenarios, unique for each engine type, engine architecture and flight mission. In such context, reliable methods for understanding and predicting the properties of the composites throughout their lifetime are critical. This project addresses the need through its aim to develop a method that predicts how mechanical properties of composites change over time and with thermo-mechanical loading. The project will develop a calculation methodology that describes the initiation and growth of damage in composites exposed to quasi-static or cyclic multiaxial loads during thermal and mechanical fatigue.

New technologies for manufacturing optimized and more intelligent tools (TOOLS)

TOOLS project aimed to implement new technologies, such us induction heating and the use of optical fiber sensors, in manufacturing of composite tools to improve their efficiency in the production of Carbon Fiber Reinforced Plastics (CFRP) components. Different CFRP materials were tested and investigated to increase heat efficiency in part manufacturing and the durability of the tool. The project has developed more intelligent tools using embedded sensors to acquire additional information about the tool itself to improve manufacturing processes and maintaining operations.
