Reinforcement of glued laminated timber beams with continuous carbon fibers

V projektni nalogi smo predstavili lastnosti in uporabo lesa ter ojačitveni material s poudarkom na pletenicah iz ogljikovih vlaken hkrati z možnostjo njune skupne uporabe z različnimi vezivnimi sredstvi. Pri eksperimentu smo obravnavali armiranje lepljenih lamelnih lesenih nosilcev s kontinuiranimi ogljikovimi vlakni in vpliv armiranja na nosilnost in mehanske lastnosti nosilca. Testiranje preizkušancev smo opravili s tri-točkovnim upogibnim preizkusom. Na podlagi rezultatov smo ugotovili, da se mehanske sposobnosti armiranih preizkušancev povečajo. Način armiranja in vezivno sredstvo močno vplivata na rezultate.In project work we presented properties and use of wood and yarn made of carbon fibers as a reinforcing material, and also possibilities of their combined usage with different binders. In the experiment we checked reinforcing of glued laminated timber beams with continuous carbon fibers and impact of the reinforcement on load bearing capacity and mechanical properties of the beam. Testing was done with a three point flexural test. Based on the results we discovered that mechanical properties of reinforced specimen increased. Method of reinforcing and binder significantly affect the results
