POLYMERS IN THE MACHINE ELEMENTS

Modernom gospodarstvu nameće se izazov postizanja ekonomski isplative proizvodnje uz istovremenu ekološki prihvatljivu izradu koja može ostvarivati tržišnu konkurentnost. S ciljem savladavanja izazova, polimerni materijali sve češće zamjenjuju neke klasične materijale u izradi strojnih elemenata. Korištenje polimera u izradi strojnih elemenata zasniva se na postizanju kompromisa između mehaničkih svojstava polimera i osiguranja funkcionalno zadovoljavajuće primjene koji mora biti i ekonomski opravdan. U svrhu proširivanja znanja o polimernim strojnim elementima ovaj završni rad bavi se iznošenjem teoretskih znanja o polimerima i njihovoj primjeni općenito. Nadalje, napravljena je podjela strojnih elemenata uz navođenje polimernih materijala koji se koriste u izradi. Također, izvršeno je ispitivanje mehaničkih svojstava poliamida 6 i akrilonitril/butadien/stirena na kidalici pomoću 3D ispisanih ispitnih tijela.Modern economy faces the challenge of achieving economically viable production which simultaneously has to have ecologically acceptable production that can gain market competitiveness. In order to overcome the challenges, polymeric materials are used more frequently instead of some classical materials used in the production of machine elements. The use of polymers in the production of machine elements is based on the compromise between mechanical properties of the polymers and the assurance of functionally satisfactory application that must be economically justified. With the purpose of extending the knowledge on polymeric machine elements, this final thesis deals with the presentation of theoretical knowledge of polymers and their application in general. Furthermore, it deals with the machine elements division and listing of corresponding polymers use in the production of particular machine elements. Ultimately, the thesis deals with the examination of mechanical properties of polyamide 6 and acrylonitrile butadiene styrene
