Properties and application of polymers in mechanical engineering

Predmet istraživanja ovog rada su polimerni materijali. Nadalje, u razradi općenito su definirani polimerni materijali, analizirana njihova struktura, svojstva te sami postupci proizvodnje. Također, prikazana je generalna metodologija s obzirom da je polimere moguće podijeliti na temelju različitih kriterija. Temeljna i opća podjela zasniva se na njihovu ponašanju pri povišenim temperaturama. U radu su također prikazani kriteriji odabira polimera u strojarstvu s obzirom na njihova svojstva i kvalitete. U zadnjem poglavlju rada analizirani su trendovi razvoja polimera u odnosu na ostale konstrukcijske materijale te je donesen zaključak da se razvoj polimera iz dana u dan kontinuirano povećava. Također su određeni, klasificirani i objašnjeni najkorišteniji polimeri u smislu povezivanja njihove strukture, svojstva te konačno primjene.The subject of this study are polymer materials. Furthermore, in the main part polymer materials are generally defined, as well as their structure, characteristics and manufacturing processes are analyzed. A general methodology is also presented since polymers can be divided based on different criteria. The fundamental and general division is based on their behavior at elevated temperatures. The paper also outlines the criteria for selection of polymers in mechanical engineering with regard to their properties and quality. In the last chapter of the paper, trends of polymer development are analyzed in relation to other construction materials and it was concluded that the development of polymers from day to day increases continuously. The most used polymers are also defined, classified and elaborated in terms of linking their structure, characteristics and lastly, their application
