Partner 1 (Coordinator)

Leibniz-Institut für Polymerforschung Dresden e.V. (IPF)

IPF will carry out the tasks of material development by fiber manufacturing of relevant amounts for upscaling using a pilot spinning line, surface modification and unique equipment for interphase characterization on composite microscale as well as the unit-cell-element (Representative Volume Element (RVE) of single fiber with interphase and matrix) for virtual design of experiments for graded interphases. Further, IPF will be responsible for the project management.


Partner 2

Luleå University of Technology (LTU)

The LTU is responsible for the development of new, industrially relevant meso-scale characterization methods of fibers and their interaction with polymer matrix. The main tasks within the project is to generate input parameters for modelling as well as deliver industrially relevant data for the final assessment of materials developed within the project. The work will include manufacturing and characterization of composites (meso-scale model composites as well as laminates for coupon tests) by means of specially designed experimental procedures that will be transferred to the industrial partner at the end of the project.


Partner 3

University of Latvia (LU)

The principal role of LU relates to numerical and analytical modelling of the effect of the fibre/matrix interphase with graded properties on the mechanical response of a fibre-reinforced composite aimed at elucidating the optimal interphase grading that would ensure increased load-bearing capacity of composite. Specific tasks include evaluation of the interphase grading effect on elastic properties, stress concentration, and strength of UD composite, and optimization of the interphase grading aiming at reduction of stress concentrations in the composite.


Partner 4

Hitachi Energy Sweden AB, Composites (Hitachi)

Hitachi provides the industrial challenge to be targeted by interphase improvements as well as the new approach and methods for screening and characterization of materials. Hitachi is also responsible for production of macro-scale tubes to be used for testing to verify that the micro- and meso-scale tests and modelling results also translate in a relevant manner to macroscopic product properties. Hitachi will be responsible for the dielectric testing within the project.

This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 958174.
