Abstract

Lesno-plastični kompozit (LPK) je inovativen material, ki združuje lastnosti lesa in plastike, s čimer ponuja okolju prijazno ter stroškovno učinkovito alternativo tradicionalnim materialom. Ta kombinacija omogoča trajno rešitev z manjšo potrebo po vzdrževanju v primerjavi z naravnim lesom. Uporaba LPK v gradbeništvu in drugih panogah prinaša številne prednosti, med katerimi so vzdržljivost, odpornost na vremenske vplive, majhen toplotni raztezek ter relativno dobre mehanske lastnosti. V diplomski nalogi smo se osredotočili na raziskovanje vpliva uporabe skorje na lastnosti LPK-ja. Skorja, kot potencialno zanimiv ligno-celulozni material, je bila uporabljena kot nadomestek za les v kompozitu. Pri izdelavi smo kot plastiko uporabili polietilen. Naša raziskava je imela za cilj razumeti, kako prisotnost skorje vpliva na različne fizikalne in mehanske lastnosti LPK materiala. Glavne ugotovitve naše raziskave so bile, da se z večanjem deleža skorje povečuje debelina LPK plošč, medtem ko gostota ostaja relativno konstantna. Poleg tega smo opazili tudi šibkejše vezi med gradniki skorje, kar je privedlo do zmanjšane mehanske trdnosti povečanja deformacije materiala. Večji delež skorje je prav tako povzročil večje vpijanje vode in s tem povečanje debelinskega nabreka.

Secondary title: Manufacturing of wood-plastic composite with bark and ployethylene
Secondary abstract: Wood-plastic composite (WPC) is an innovative material that combines the properties of wood and plastic, offering an environmentally friendly and cost-effective alternative to traditional materials. This combination provides a durable solution with less maintenance required compared to natural wood. The use of WPC in construction and other industries brings numerous advantages, including durability, resistance to weathering, low thermal expansion, and relatively good mechanical properties. In our thesis, we focused on investigating the influence of bark utilization on the properties of WPC. Bark, as a potentially interesting ligno-cellulosic material, was used as a substitute for wood in the composite, while polyethylene was used as the plastic component in the manufacturing process. Our research aimed to understand how the presence of bark affects the various physical and mechanical properties of WPC material. The main findings of our study were that the thickness of WPC boards increases with an increasing proportion of bark, while the density remains relatively constant. Additionally, we observed weaker bonds between bark particles, leading to reduced mechanical strength and increased material deformation. A higher proportion of bark also resulted in greater water absorption and thus increased swelling of the material.
