Abstract

Uporaba bioloških materialov v polipropilenskih kompozitih se zaradi dokazanih izboljšanih lastnostih povečuje. Vseeno pa je v literaturi zaslediti zelo malo podatkov o njihovih triboloških lastnostih kot sta trenje in obraba. Slednje pa je zelo pomembno saj te lastnosti določajo obnašanje takšnih materialov v realnih aplikacijah in kažejo na njihovo uporabnost v industriji. V tej zaključni nalogi so bile tako raziskane tribološke lastnosti lesno polimernih kompozitov iz polipropilena kot tudi recikliranega polipropilena. Glede na trenje in obrabo so se v eksperimentu bolje izkazali kompoziti z večjo vsebnostjo lesenih vlaken. Prav tako so kompoziti iz čiste matrice polipropilena, proti reciklirani matrici z istim masnim deležem lesa, izkazali boljše tribološke lastnosti.

Secondary title: Tribological properties of wooden polymer composites made out of polypropilene
Secondary abstract: Use of biological materials in polypropylene composites due to proven improved properties. However, very little data on their tribological properties such as friction and wear can be found in the literature. The latter is very important, as these properties determine the behavior of materials in real applications and indicate their applicability in industry. In this final paper, the tribological properties of wood-polymer composites made of polypropylene as well as recycled polypropylene were investigated. In terms of friction and wear, composites with a higher wood fiber content performed better in the experiment. Composites made of pure polypropylene matrix, against recycled matrix with the same wood content by weight, also showed better tribological properties.
