Vpliv graviranja površine kompozita in aluminijeve zlitine na natezno trdnost lepljenega spoja : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni program
Gričar, Miha, strojnik
V zaključni nalogi smo raziskovali povezavo med laserskim graviranjem površine aluminijeve zlitine in karbonskega kompozita ter natezno trdnostjo lepljenih spojev. Tekom dela smo določili parametre ...laserskega graviranja, določili vzorce tekstur, izvedli meritve kotov omočenja za različne teksture, izdelali lepljence in jih zlepili. Lepljene spoje smo nato natezno testirali do porušitve in obdelali podatke. Površine smo po nateznem preizkusu analizirali in določili tip porušitve. Parametri graviranja vplivajo na globino in konsistentnost gravur. Potrdili smo, da graviranje površin vpliva na njihovo omočljivost. Tudi čas po graviranju, zaradi nastanka oksidnega sloja in kontaminacije, vpliva na omočljivost površin. Ugotovili smo, da graviranje površine lahko pretirano poškoduje površino karbonskega kompozita in s tem poveča verjetnost delaminacije površine lepljenca ob obremenitvi, delaminacija lepljenca pa povzroči nižjo trdnost lepljenega spoja.
