“…4(c). Moreover, in the literature it is reported that the similar yield point is also observed for carbon fiber with high aspect ratio filled elastomer systems, 57,58 which is attributed to the matrix-fiber adhesion rupture. In our simulated case the yield point may result from the breakage of the filler fractal structure mediated through polymer chains.…”

By employing an idealized model of a polymer network and filler, we have investigated the stress-strain behavior by tuning the filler loading and polymer-filler interaction in a broad range. The simulated results indicate that there actually exists an optimal filler volume fraction (between 23% and 32%) for elastomer reinforcement with attractive polymer-filler interaction. To realize this reinforcement, the rubber-filler interaction should be slightly stronger than the rubber-rubber interaction, while excessive chemical couplings are harmful to mechanical properties. Meanwhile, our simulated results qualitatively reproduce the experimental data of Bokobza. By introducing enough chemical coupling between the rubber and the filler, an upturn in the modulus at large deformation is observed in the Mooney-Rivlin plot, attributed to the limited chain extensibility at large deformation. Particularly, the filler dispersion state in the polymer networks is also characterized in detail. It is the first demonstration via simulation that the reinforcement mechanism stems from the nanoparticle-induced chain alignment and orientation, as well as the limited extensibility of chain bridges formed between neighboring nanoparticles at large deformation. The former is influenced by the filler amount, filler size and filler-rubber interaction, and the latter becomes more obvious by strengthening the physical and chemical interactions between the rubber and the filler. Remarkably, the reason for no obvious reinforcing effect in filled glassy or semi-crystalline matrices is also demonstrated. It is expected that this preliminary study of nanoparticle-induced mechanical reinforcement will provide a solid basis for further insightful investigation of polymer reinforcement.

“…The PE used was a linear medium density metallocene catalyzed polymer [density 5 940 kg m 23 , MFR (1908C/2.16 kg)], Borcene RM7403, kindly supplied by Borealis (Norway). Composites of CF and PE were prepared at loadings of 0, 1, 3,5,8,10,15,20,25, and 30 wt % CF using a Dr. Collin 25-mm corotating intermeshing twin screw extruder fitted with a 3-mm strand die and a screw speed of 200 rpm. The temperature settings over six zones from the feed section to die head increased from 190 to 2058C resulting in a melt temperature of 2128C.…”

“…Recycled CF obtained form such processes can then be used to reinforce thermoplastics and thermosets or improve the electrical conductivity of insulating polymers, a more attractive proposal than using high cost virgin CF. The incorporation of virgin CF into a range of polymers and polymer blends, including high density polyethylene (HDPE), 2 polypropylene (PP), 2,3 Nylon 6,6, 4 styrenebutadiene-styrene (SBS), 5 epoxy, 6 ethylene-vinyl acetate copolymer (EVA), 7 and HDPE/PMMA blends 8 have been widely reported. However, the published literature on composites of recycled CF and polymers is limited.…”

Composites of recycled carbon fiber (CF) with up to 30 wt % loading with polyethylene (PE) were prepared via melt compounding. The morphology of the composites and the degree of dispersion of the CF in the PE matrix was examined using scanning electron microscopy, and revealed the CF to be highly dispersed at all loadings and strong interfacial adhesion to exist between the CF and PE. Raman and FTIR spectroscopy were used to characterize the surface chemistry and potential bonding sites of recycled CF. Both the Young's modulus and ultimate tensile stress increased with increasing CF loading, but the percentage stress at break was unchanged up to 5 wt % loading, then decreased with further successive addition of CF. The effect of CF on the elastic modulus of PE was examined using the Halpin-Tsai and modified Cox models, the former giving a better fit with the values determined experimentally. The electrical conductivity of the PE matrix was enhanced by about 11 orders of magnitude on addition of recycled CF with a percolation threshold of 7 and 15 wt % for 500-lm and 3-mm thick samples.

The interfacial properties between the asphalt mastic and fibers plays an essential role in the fiber-enhanced asphalt mixture properties. However, there is a lack of comprehensive studies on the indicators to evaluate the interfacial interaction ability of fibers with the asphalt mastic. Therefore, this paper selected three types of basalt fibers (denoted as A-BF, B-BF and C-BF) coated with different impregnating agents to prepare the fiber asphalt mastic. The Dynamic Shear Rheometer (DSR) test-based indicators, pull-out strength, and adhesion work were used to access the fiber asphalt mastic interfacial interaction ability. The differences between different indicators were compared and analyzed. The results show that all the selected indicators in this paper can effectively reflect the different fiber asphalt mastic interfacial properties. The evaluation results with different indicators are consistent. The interfacial interaction between fibers and the asphalt mastic increases with increasing temperature. The evaluation result with adhesion work is the most accurate. However, the pull-out strength test is simple, and the test result correlates well with adhesion work, which can be adopted daily to evaluate the fiber asphalt mastic interfacial properties.
