Effects of temperature and load on the creep performance of CNT reinforced laminated glass fiber/epoxy composites

摘要

Present study aims at evaluation of creep properties of glass fiber/epoxy (GE) composite, and GE composites modified with 0.1 wt.% pristine carbon nanotube (PCNT-GE) and 0.1 wt.% oxidized carbon nanotube (OCNT-GE) under varied temperatures (50 degrees C, 80 degrees C, 110 degrees C). Further, creep behavior has also been elucidated with different loads at 110 degrees C. Burger's model has been incorporated to predict the creep response of the composites. Results indicate that at lower temperature and load, presence of PCNT and OCNT in GE composite leads to reduction in creep strain and strain rate. Further, functionalized CNT seems to impart a better creep resistance than that of pristine CNT in the GE composite at all the creep testing temperatures and loads.
