The aim of the diploma thesis is preparation of glass fiber-reinforced polymer composites with controlled interphase using the method of plasma-enhanced chemical vapour deposition (PECVD) and tetravinylsilane as the monomer. The theoretical part focuses on literature recherché on plasma and plasma polymerization, thin films and composites. Experimental part deals with materials and equipment used for fiber surface modification and preparation of fiber-reinforced composites. The fiber surface modification was done using different deposition conditions. The chemical and mechanical analysis of formed interlayers was done using FTIR spectrometry and scratch test. The effect of surface modification was evaluated by acquired interlaminar shear strength using short beam shear test.
Cieľom diplomovej práce je príprava polymerných kompozitov vyztužených sklenenými vláknami s riadenou medzifázou za použitia metódy plazmochemickej depozície z plynnej fáze a monomeru tetravinylsilanu. Teoretická časť je zameraná na literárnu rešerš o plazme, plazmovej polymerácií, tenkých vrstvách a kompozitoch. Experimentálna časť popisuje použité materiály a aparaturu použitú na povrchovú modifikáciu sklenených vlákien a prípravu vláknom vyztužených kompozitov. Povrchová úprava sklenených vlákien prebiehala za rôznych depozičných podmienok. Chemické a mechanické analýzy vytvorenej medzivrstvy prebiehali za použitia FTIR spektrometrie a vrypového testu. Vliv povrchovej úpravy bol zistený pomocou získanej interlaminárnej šmykovej sily použítím testu krátkych trámečkov.
