The core experimental part relies on manufactured specimens and quality assurance for the scale down structures. In order to satisfy both – a required physical (buckling) behaviour and a test set-up, several assumptions and restrains have been implemented in design of manufacturing and non-destructing testing equipment. In particularly an emphasis has been devoted for design and metalworking of CFRP cylinder specimen manufacturing mandrel. Dedicated non-destructive geometrical imperfection/lay-up configuration and thickness variation control equipment based on already available ultrasound inspection device was required to be upgraded. Furthermore a geometrical imperfection combined with a buckling mode scanner was required in order to measure deflection dimples at inner surface of the test article.
