On 7 February 2019, at the SAMPE Symposium in Dresden, Jonas Müller, M.Sc. was presented with the SAMPE innovation award. The prize is awarded by SAMPE Germany for outstanding scientific studies, diploma dissertations or doctorate theses. The research should focus on innovative material applications, new processing processes or interesting material combinations for composites.
Jonas Müller, who works as a scientific assistant at IKV, was awarded the prize for his Master's thesis "Analytical and numerical investigation of damage development in continuous fibre-reinforced plastics under fibre-parallel load". In the design of fibre-reinforced plastic parts, the main loading direction is in the fibre direction. For this reason, it is important to have a better understanding of the damage mechanisms of the composite material at the micro level and also be able to model them. To model the identified damage mechanisms, use is made of the shear-lag model. With this model it is possible to calculate the strength of the examined unidirectional layer (UD layer). During the course of the study, the model was extended by a calculation of the fracture energy and an examination of the damage development under cyclic, fibre-parallel tensile load. Based on cyclic modelling, it is now possible to predict more accurately the life expectancy of the UD layer. The tests showed that the properties under quasi-static load of the UD layer can be satisfactorily described by the shear-lag model. Furthermore, cyclic modelling shows highly promising results.
IKV warmly congratulates Jonas Müller on his award.
