The present study attempts to investigate the influence of multiwalled carbon nanotubes (MWCNTs) and graphite nanoplatelets (GNPs) on thermal conductivity (TC) of nanoreinforced polymers and nanomodified carbon fiber epoxy composites (CFRPs). Loading levels from 1 to 3% wt. of MWCNTs and from 1 to 15% wt. of GNPs were used. The results indicate that TC of nanofilled epoxy composites increased with the increase of GNP content. Quantitatively, 176% and 48% increase of TC were achieved in nanoreinforced polymers and nanomodified CFRPs, respectively, with the addition of 15% wt. GNPs into the epoxy matrix. Finally, micromechanical models were applied in order to predict analytically the TC of polymers and CFRPs. Lewis-Nielsen model with optimized parameters provides results very close to the experimental ones in the case of polymers. As far as the composites are concerned, the Hashin and Clayton models proved to be sufficiently accurate for the prediction at lower filler contents.

Temperature And Humidity

This study experimentally analyzed the hygrothermal effect on the static and fatigue strengths of multiwalled carbon nanotubes (CNTs)/epoxy composites. The results show that the static and fatigue strengths decreased slightly at 25°C/85% RH environments compared with those tested under the 25°C/60% RH condition. However, the strengths decreased substantially under the 40°C/85% RH condition, indicating that the combined temperature and humidity environments weaken the interfacial adhesion between the CNT surfaces and the epoxy matrix.
