Research in cooperation with University of Bath and Lublin University of Technology will be carried out with the use of the Diamond Light Source synchrotron in Great Britain. Once a year, this one of the most advanced scientific centres in the world awards funding to the most interesting research projects selected through peer review. Under this competition, funding was awarded to a project involving researchers from Lodz University of Technology. The synchrotron acts like a giant microscope, enabling measurements of all sorts of structures from the chemical analysis of fossil fuels to the microstructure of metals to the study of viruses. The machine accelerates electrons almost to the speed of light and, thanks to the phenomenon of diffraction (bending of light rays), it is possible to analyse the examined structures with a very high resolution - 10,000 times greater than with the use of a classical microscope.
A study using microtomography is planned to experimentally measure residual stresses in thin-walled carbon fibre composite columns and the effect of these stresses on the stability and load-bearing capacity of the structure,’ says professor Tomasz Kubiak.
The scientists from the international team have shown that residual stresses created during the composite manufacturing process can significantly improve its stiffness and performance under load. Another research objective is to investigate these stresses in detail. This will be carried out as part of the project on the British Diamond Light Source synchrotron.
