EM-Characterization of Composite Structures

Purpose and goal

The aim of the project has been to verify the function of a measurement system so that the structure of a composite panel is recreated with the algorithms developed in the project. This has been achieved with new developed algorithms and a methodology published in an international journal. Geometric defects and variations in electrical conductivity of structures within a composite panel have been depicted by newly developed algorithms. The scientific work of the project has been published as technical reports, conference proceedings and an international journal article.

Expected results and effects

A new method for characterizing geometric and electromagnetic defects in composite structures has been developed and demonstrated. Advanced theory has been combined with experimental verification to identify the defects. The research results have been published internationally, both as conference papers and as a journal article. The work is part of the dissertation of two PhD students. The potential of the technology has been demonstrated and there is a future industry need for this type of technology. Collaboration between industry and LTH has been deepened through this project.

Planned approach and implementation

The industry has formulated a technology need and LTH has developed practically useful solutions that meet the needs of industry. The cooperation between industry and LTH has worked well with frequent work meetings held once a month at LTH. Two of the industry´s project members have been "cross-border" in the form of adjunct professors at LTH. They have also served as deputy supervisors to the two PhD students. In addition to theoretical work, experimental activities have also been carried out at LTH, which has been a major advantage.
