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.

In this study, we present a novel approach to graft a large number of poly(glycidyl methacrylate) (PGMA) chains onto the carbon fiber (CF) surface through reversible addition-fragmentation chain transfer (RAFT) polymerization. Characterization results of FT-IR, XPS and TGA demonstrated that PGMA was covalently combined with carbon fibers. The CF/epoxy composites were obtained by addition of pristine CF and CF functionalized with poly(glycidyl methacrylate) (CF-PGMA) into epoxy resin. Experiment results revealed that the grafting of PGMA chains on the CF surface could increase significantly roughness and number of active groups of CF, which enhanced interface and mechanical properties of the composites. The compression strength, tensile strength, flexural strength and interfacial shear strength (IFSS) of CF-PGMA/epoxy composites are enhanced by at least 63.1%, 37.9% 55.6% and 122.5%, respectively, compared to pristine carbon fiber/epoxy composites. This enhancement indicates that surface modification of the carbon fibers by RAFT technique is a potential method to preparing CF-reinforced polymer matrix composites with excellent mechanical properties.

This paper verifies the feasibility of the relative entropy method in selecting the most suitable statistical distribution for the experimental data, which do not follow an exponential distribution. The efficiency of the relative entropy method is tested through the fractional order moment and the logarithmic moment in terms of the experimental data of carbon fiber/epoxy composites with different stress amplitudes. For better usage of the relative entropy method, the efficient range of its application is also studied. The application results show that the relative entropy method is not very fit for choosing the proper distribution for non-exponential random data when the heavy tail trait of the experimental data is emphasized. It is not consistent with the Kolmogorov–Smirnov test but is consistent with the residual sum of squares in the least squares method whenever it is calculated by the fractional moment or the logarithmic moment. Under different stress amplitudes, the relative entropy method has different performances.
