The paper presents the main conclusions of research on strengthening wooden elements with fibre composites, especially tapes and matting based on carbon CFRP fibres, which was carried out in the laboratories of the Silesian and Wrocław Technical Universities. Research involved testing elements at a technical scale with different load bearing levels. Tests were carried out on elements with both extemal strengthening and also strengthening inserted into strengthened elements. The goal of the paper is to present a straight-forward and effective method for strengthening wooden construction elements using fibre composites.
Effect of variable temperature and moisture content conditions on selected properties of wood-CFRP composite Intended structural application of wood-CFRP composite requires analysis of its properties in time function, including environmental conditions changes. The paper presents results of selected mechanical and physical properties of composite, using artificial aging methods. It was shown that artificial aging cycles determined according to standards and other regulations, relating to 1 year of natural aging, caused a decrease of composite's density, as well as a significant decrease of Young's modulus, with negligible change in the values of bending strength.
