description

Bakalaura darba mērķis ir noskaidrot mitruma ietekmi uz epoksīda sveķu un ONC nanokompozītmateriāla mehāniskajām īpašībām atkarībā no ONC masas koncentrācijas. Darba gaitā ir izveidoti jauni epoksīda sveķu un ONC nanokompozīta paraugi vairākās masas koncentrācijās. Paraugi testēti, veicot kvazistatiskās vienass stiepes eksperimentus līdz parauga sabrukšanai. Blīvums noteikts ar hidrostatiskās svēršanas metodi. Mitruma ietekmes novērtēšanai uz nanokompozīta mehāniskajām īpašībām izmantoti tādu pašu epoksīda sveķu paraugi, kas 32 mēnešus tika turēti 29% un 90% atmosfēras mitrumos. Tika nomērītas un salīdzinātas paraugu elastības moduļa un blīvuma vērtības. Eksperimenti veikti istabas apstākļos. Noteikts, ka mitrums samazina epoksīda sveķa un ONC nanokompozītu elastības moduļu vērtības par 15%-20%, taču ONC koncentrācijas ietekme ir niecīga.
