Jekleno pločevino iz skupine PROTAC odlikujejo visoke mehanske in protibalistične karakteristike tudi že pri relativno majhnih debelinah. Mehanske lastnosti jekla PROTAC 500 so poznane in na voljo uporabnikom. Podatki o toplotnih lastnostih (toplotni prevodnosti, specifični toploti in temperaturni prevodnosti) pa danes žal še niso na voljo. V okviru diplomskega dela je bila izvedena študija in ocena delovanja naprave za določevanje toplotnih lastnosti Hot Disk TPS 2200 in opis standardov skupine ISO 22007, s posebnim poudarkom na standardu ISO 22007-2. V okviru eksperimentalnega dela smo izvedli meritve toplotne prevodnosti in specifične toplote ter izračunali temperaturno prevodnost jeklene pločevine PROTAC 500 v skladu s standardom ISO 22007-2 pri sobni temperaturi (približno 22 °C). The steel plates from the PROTAC group are characterised by high mechanical and armour protection characteristics, even at relatively small thickness. The mechanical properties of PROTAC 500 steel are known and available to users. Data on the thermal properties (thermal conductivity, specific heat and temperature conductivity), unfortunately, are not yet available. This bachelor’s thesis is based on a practical study and an assessment of the performance of the device for determining the thermal properties, Hot Disk TPS 2200, and a description of the ISO 22007 group standards, with particular reference to the ISO 22007-2 standard. As part of the experimental work, we performed measurements of thermal conductivity and specific heat and calculated the temperature conductivity of PROTAC 500 steel plates in accordance with the ISO 22007-2 standard at room temperature (approximately 22 °C). |
