Polymerní kompozity s vyššími užitnými vlastnostmi

Abstract

Polymerní kompozity s vyššími užitnými vlastnostmi jsou materiály, u kterých je kladen důraz na specifické chemické a mechanické vlastnosti s ohledem na jejich širokou míru uplatnění. Jejich hlavními výhodami jsou vysoká pevnost a houževnatost v porovnání s jejich nízkou hmotností a hustotou. Pro dobré výsledné vlastnosti je třeba zajistit vysokou adhezi výztuže a matrice na jejich mezifázovém rozhraní byly připraveny vrstvy plazmově polymerovaného tetravinylsilanu (pp-TVS) na svazky skleněných vláken při různé tloušťce a efektivním výkonu. Připravené vrstvy pp-TVS byly analyzovány z hlediska chemického složení (RBS, FTIR, XPS) a také mechanických vlastností (NI-AFM). Pro posouzení míry adheze byly použity testy pro smykovou pevnost na rozhraní a test vytrhávání svazku vláken na rozhraní vlákno matrice.

High performance polymer composites are materials with emphasis on specific chemical and mechanical properties due to their broad scope of applications. The main advantages are high strenght and toughness in comparison with their low weight and density. An increased adhesion at composite interfaces is important to ensure excellent composite properties. Bundles of glass fibers were coated by plasma-polymerised interlayers of tetravinylsilane (pp-TVS) of different thicknesses and at different effective powers. The prepared interlayers of pp-TVS were analyzed to evaluate chemical composition (RBS, FTIR, XPS) and mechanical properties (NI-AFM). Microindentation test and fiber-bundle pull-out test were used to determine the interfacial shear strenght.
