• Dates: 2009-2012
• Place: Silesian University of Technology
• PI: Wojciech Moczulski
• Team: Andrzej Katunin, Marek Fidali
• Cooperating staff: Adam Gnatowski
• Funding source: Ministry of Science and Higher Education of Republic of Poland

The scientific problem solved within this grant was the assessment of the behavior of the laminated composites under the influence of self-heating temperature and the impact of this temperature on the initiation and propagation of cracks and delaminations in the laminate. The aim of the research undertaken was assessing the impact of the self-heating temperature on the behavior of the laminate, in particular on the fatigue of the laminate and the change in properties in terms of the glass transition temperature and after the transformation occurs when the glass transition temperature is exceeded, as well as the impact of the self-heating temperature on the propagation of damage such as cracks and delamination, occurring e.g., in means of transport (aircraft, yachts, etc.). The performed theoretical, numerical, and experimental results allowed deep investigation of the self-heating effect and constructing fatigue models, describing the phenomenon.
