20.500.12556/DKUM-63116 IZBOLJŠANJE VPETJA OGLJIKOVIH VLAKEN V CEMENTNI MATRICI BOND IMPROVEMENT OF CARBON-FIBER YARN EMBEDDED IN CEMENT MATRIX V diplomskem delu obravnavamo problematiko vpetja ogljikovih vlaken v cementni matrici. Podajamo teoretično ozadje problema ter lastnosti materialov, ki smo jih uporabili v eksperimentalnem delu. Prav tako so navedeni splošni principi izboljšanja vpetja vlaken v cementni matrici. V hipotezi smo predpostavili, da lahko vpetje izboljšamo na dva načina, in sicer z impregniranjem vlaken s cementnim mlekom ter povečanjem trenja na mejni površini z mikro delci mlete odpadne avtomobilske gume. Impregnacija se je pokazala kot dobra rešitev, z mleto gumo pa nismo dosegli pričakovanih rezultatov. In the thesis we address the problem of carbon-fiber yarn bonding into cement matrix. We are presenting theoretical background of the problem and properties of materials we used in experiments. Also, we showed general approaches of bonding improvements in cement matrix. The hypothesis was, there were two ways to improve bonding; first one was to impregnate carbon-fiber yarn with cement milk and the second one was friction improvement with microparticles made of waste tyres. Fiber impregnation was a good solution, but samples with rubber particles did not reach expected results. z vlakni utrjeni kompoziti ogljikova vlakna preizkus puljenja fiber-reinforced composites carbon fibres pull-out true true false [I.
