On the project

Kvantifikace role konopných vláken na samovyhojovací procesy ve vybraných kompozitech na základě lomově-mechanických parametrů (KvaRK)

Description in English
The proposed project deals with the role of distributed hemp fibres on self-healing processes in selected fine-grained composites based on a brittle matrix. The main goal of the project is the quantification of the role of hemp fibres during controlled damage of the studied materials by means of numerical analyses and advanced assessment of experimental data from fatigue and mechanical fracture tests. The aim of the project shall be achieved through the deepening of the existing cooperation of three scientific teams with rich experience in the field of fatigue experiments, fracture tests and hemp fibres based materials – team FRACTIGUE from the Institute of Physics of Materials, Czech Academy of Sciences, v. v. i., team of the Faculty of Civil Engineering of the Brno University of Technology and team of the Faculty of Civil Engineering of TU Wien.
