Abstract:Bukovo žagovino smo uporabili kot ojačitveno komponento pri pripravi biokompozitov z uporabo polioksimetilena % POM in polimlečne kisline % PLA kot polimerne matrice. Z ekstrudiranjem in brizganjem smo pripravili materiale z različno vsebnostjo žagovine, in sicer 5, 10 in 15 ut. %. Določili smo njihove mehanske (E modul, upogibna in natezna trdnost, raztezek) in termične (tališče, steklasti prehod) lastnosti. Rezultati v primeru obeh matric kažejo, da žagovina deluje kot ojačitev za upogibne obremenitve in pri matrici POM tudi za natezne obremenitve. Dodatek žagovine v matrico POM ali PLA dvigne maksimalno temperaturo uporabe kompozitov. Nove materiale odlikuje nizka gostota, njihova glavna pomanjkljivost pa je krhkost. So dobra in cenovno ugodna alternativa kompozitom z vgrajenimi steklenimi vlakni.

Title:Suitability evaluation of beech sawdust as reinforcement component in the preparation of thermoplastic biocomposites
Abstract:Beech sawdust was used as reinforcing component for the preparation of biocomposites with polyoxymethylene % POM and polylactic acid % PLA as polymer matrix. Materials with different portions of sawdust, e.g. 5, 10 and 15 wt. %, were prepared by using extrusion and injection techniques. Their mechanical (E modulus, flexural and tensile strength and strain) as well as thermal (melting point, glass transition) properties were determined. The results indicate that sawdust acts as reinforcement of the composites in the case of flexural stress and also tensile strength by POM matrix. Addition of sawdust to POM and PLA increases maximal temperature of biocomposite utilization. The main advantage of new materials is low density. Despite their brittleness they are convenient, low-cost alternatives to composites reinforced with glass fibres.
