Abstract

Polimerni kompoziti se zaradi svojih lastnosti čedalje več uporabljajo tudi v konstrukcijske namene. Namen magistrskega dela je bil preučevanje in karakterizacija toplotnih in mehanskih, ter lomno-mehanskih lastnosti različnih termoplastičnih polimernih kompozitov, ki bi lahko zamenjali trenutni uporabljeni material za izdelavo ohišja konektorja pri spajanju povoznih plošč. Izvedli smo DSC in DMA analizo za študij toplotnih lastnosti in natezni preizkus, preizkus udarne žilavosti po Charpyju in lomno-mehanski preizkus za preučevanje porušitve materiala. Ugotovili smo, da se v temperaturnem območju uporabe konektorja najbolje obnese termoplastični poliuretan ojačan z dolgimi steklenimi vlakni.

Secondary title:	Optimisation of the polymer material of the connector frame
Secondary abstract:	Polymer composites are increasingly used for design purposes due to their properties. The purpose of the master’s thesis was the study and characterization of thermal, mechanical and fracture mechanical properties of various thermoplastic polymeric composites which could replace the current material which is used for the connector. We performed DSC and DMA analysis to study thermal properties and tensile test, Charpy impact test and fracture mechanics test for the study of material collapse. It has been found that thermoplastic polyurethane reinforced with long glass fibers exhibits best behaviour in our operating temperature range.
