Strukturne, elastomehanske in akustične lastnosti lesa gorskega javorja (Acer pseudoplatanus L.) z rebrasto teksturo : diplomsko delo - univerzitetni študij - 1. stopnja = Structural, elastomechanical and acoustic properties of sycamore maple (Acer pseudoplatanus L.) wood with fiddleback figure : B. Sc. Thesis - Academic Study ProgrammesJerman, Jan, gozdarRebrasta tekstura v lesu gorskega javorja (Acer pseudoplatanus L.) je znan in dobro opisan pojav, manj raziskan pa je njen vpliv na fizikalne, mehanske in akustične lastnosti ter dimenzijsko ... stabilnost lesa. V raziskavi smo vzorčili les gorskega javorja z rebrasto teksturo ter les navadnega gorskega javorja. Strukturne lastnosti smo vizualno določali makroskopsko ter s svetlobno mikroskopijo. Na uravnovešenih preizkušancih smo opravili meritve gostote in širine branik ter dimenzijske stabilnosti, nato pa smo preizkušance dinamično mehansko vzbujali vzdolž in prečno na lesna vlakna. Elastomehanske lastnosti v vseh anatomskih smereh lesa smo določili še z ultrazvokom ter izvedli tudi statični upogibni preskus. Na mikroskopski ravni rebraste teksture, primerjalno s premim potekom vlaken, ni bilo mogoče jasno razločiti. Rebrasta tekstura ni izkazala statistično pomembnega vpliva na gostoto in dimenzijsko stabilnost javorjevega lesa. Upogibna trdnost in dinamičen ter statičen upogibni modul elastičnosti obeh tipov lesov so bili primerljivi. Dušenje zvoka lesa navadnega gorskega javorja in javorja z rebrasto teksturo vzdolž in prečno na lesna vlakna je bilo primerljivo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
