Kivonat

Számos kutatás foglalkozik természetes anyagokból készül szigetelő anyagokkal, közöttük a kéreggel is. A kéregből készült lemezek fizikai és mechanikai tulajdonságai rendszerint rosszabbak az ugyanolyan körülmények között készült faalapú lemezek tulajdonságainál. Ennek a tanulmánynak a célja az, hogy megvizsgálja a Pannónia nyár kérgéből készült hőszigetelő lemez tulajdonságai rövid üvegszál belekeverésével, random elrendezésű üvegszál szövet, valamint üvegszálas háló és üvegszálas szőtt szövet felületre ragasztásával, illetve a felszín alá helyezett üvegszálas háló segítségével javíthatók-e. További vizsgálat során a panelek hővezetését próbáltuk javítani a kéreg forgácsok hőkezelésével. A cél sűrűség 350 kg/m3 volt, az elkészült panelek hővezetése 0,067 és 0,078 W/m·K közötti volt. A megerősítéseknek csak gyenge hatása volt a hővezetésre és a mechanikai tulajdonságokra. A hővezetést elsősorban a sűrűség befolyásolta, bár a nyersanyag előkezelése csökkentette a panelek hővezetését.

Kulcsszavak: fakéreg, hőszigetelés, erősítés, üvegszál, hőkezelés
