Abstract:V diplomskem delu smo predstavili lastnosti in karakteristike nekaterih ojačitvenih materialov s poudarkom na ogljikovih vlaknih in CFRP kompozitih ter možnosti njihove uporabe v lesenih konstrukcijah. V eksperimentalnem delu smo opravili natezne in upogibne preizkuse na ojačanih in neojačanih vzorcih različnih dimenzij. Na podlagi rezultatov smo ugotovili, da so vzorci ojačani z ogljikovimi vlakni in CFRP lamelami dosegli večje natezne in upogibne trdnosti ter module elastičnosti v primerjavi z neojačanimi vzorci. Pri ekonomski raziskavi smo s pomočjo vrednostne analize ugotavljali smotrnost uporabe ogljikovih vlaken za ojačitev lesenih konstrukcijskih elementov. Izkazalo se je, da je ojačitev z ogljikovimi vlakni in s CFRP lamelami dosegla nižji rang v primerjavi s povečanim prerezom lesenega elementa, predvsem zaradi relativno visoke cene ogljikovih vlaken.

Title:STRENGTHENING OF TIMBER STRUCTURES WITH CONTINUOUS CARBON FIBRES AND CFRP COMPOSITES
Abstract:In the thesis we presented the properties and characteristics of some strengthening materials with the focus on carbon fibres and CFRP composites and their possible application in timber structures. In the experimental part, we carried out tension and bending tests on samples of different dimensions with and without strengthening. Based on the experimental results we found that the samples strengthened with carbon fibres and CFRP plates showed greater tension and bending strenghts as well as a greater modulus of elasticity compared to samples without strengthening. We did the economic research with the help of the value analysis on the feasibility of using carbon fibres for strengthening of timber structural elements. The results have shown that strengthening with carbon fibres and CFRP plates achieved a lower rank than enlarging the sectional area of the timber element, manly because of the relatively high cost of carbon fibres.
Keywords:timber structural elements, carbon fibres, composites, strengthrning, tension test, bending test
