Termoplastični kompoziti z visoko toplotno prevodnostjoPešl, Teja ...V prispevku bomo predstavili krojenje toplotne prevodnosti polimernih materialov v kombinaciji z njihovimi mehanskimi lastnostmi. Polimerni kompozit je sestavljen iz polikarbonatne (PC) ... termoplastične matrice, ki ji je za zvišanje toplotne prevodnosti dodan borov nitrid (BN). S pomočjo različnih kompatibilizatorjev pri ternarnem kompozitu dosežemo različne kombinacije toplotne prevodnosti in mehanskih lastnosti. Kompavndiranje smo izvedli na dvopolžnem ekstruderju. V PC matrico smo dodali 50 % BN in 5 % različnih kompatibilizatorjev. Za izvedbo karakterizacije smo preizkušance pripravili s postopkom brizganja, preizkušanci pa so bili skladni z oblikama ISO 527 tip 1BA in ISO 178 oz. ISO 179. Upogibni E modul, upogibna trdnost, raztezek pri upogibni trdnosti, toplotna prevodnost in temperatura steklastega prehoda so močno odvisni od uporabljenega kompatibilizatorja. Pri visoki upogibni togosti dobimo tudi najvišjo upogibno trdnost, hkrati je ta kompozit najbolj krhek, ima pa najvišjo toplotno prevodnost. Najbolj žilav kompozit dobimo pri srednjih vrednostih upogibne togosti in trdnosti, hkrati je toplotna prevodnost najnižja. Delo je bilo opravljeno v okviru projekta PolyMetal - Interreg SLO-AT, prednostna os krepitev čezmejne konkurenčnosti, raziskav in inovacij, kjer razvijamo stroškovno učinkovit polimerni material kovinskega videza in otipa.
