“…However, multiple matrix cracks are observed under the fracture plane of the multiscale composite (the multiple cracking becomes less sharp on the graph due to the polishing). The multiple matrix cracks are also observed in case of the multiscale composites reinforced by combined SCFs and CNFs [34]. The formation of the multiple cracks gives hints that the stress field in the matrix between SCFs is homogenized with the presence of nanoparticles.…”

“…This may be a promising composite formulation route to combine microfillers at medium to high concentrations, and nanofillers at low concentrations into polymer matrices. It was revealed in our previous work that combined use of SCFs and carbon nanofibers (CNFs) in EP resin leads to a synergetic role on the mechanical properties of the matrix [34]. The composites filled with combined SCFs and CNFs displays better mechanical properties than the materials rein-forced only with SCFs or CNFs.…”

“…However, a combination of two kinds of nanofillers, e.g. CNFs and nanoparticles, was not associated with synergetic effects [34]. It is assumed that that the common use fillers with distinctly different scale sizes is the key issue for eventual synergism.…”

Abstract. It was demonstrated in our previous work that the combined carbon nanofibers (CNFs) and microsized short carbon fibers (SCFs) in epoxy (EP) leads to significant improvements in the mechanical properties of the matrix. In this work, the effect of nano-SiO 2 particles, having an extremely different aspect ratio from CNFs, on the tensile property and fracture toughness of SCFs-filled EP was studied. It was revealed that the combined use of SCFs and silica nanoparticles exerts a synergetic effect on the mechanical and fracture properties of EP. Application of SCFs and the nanoparticles is an effective way to greatly enhance the modulus, strength and fracture toughness of the EP simultaneously. The synergetic role of the multiscale fillers was explained by prominent changes in the stress state near the microsized fillers and the plastic zone ahead of the crack tip. The synergetic role of multiscale fillers is expected to open up new opportunities to formulate highperformance EP composites.

“…The fatigue crack growth behaviors at low frequency are needed to be investigated as a next step of research in order to discuss the effect of creep deformation. In addition, recently the synergetic effects of nano and micro-size reinforcement on the fracture toughness of epoxy resin composite have been reported (15), (16) . These effects are also expected for improving the fatigue crack growth resistance of the present composite, which will be in future work.…”

Fatigue crack growth behavior of the epoxy resin reinforced by silica particles was investigated at various temperatures below glass-transition temperature. K max versus da/dt crack growth curves showed the temperature dependence, where the crack growth resistance decreased with increasing temperature. On the other hand, ∆J versus da/dt crack growth curves showed two separated bands: one band corresponded to room temperature (22 o C) and the other corresponded to elevated temperatures (50, 80 o C). The hysteresis loops showed a clear nonlinear deformation behavior at elevated temperatures, while linear deformation behavior was found at room temperature. Fracture surface observations revealed two different crack growth mechanisms at each temperature. The crack propagated along the micro-cracks nucleated in the interface or in the matrix near the interface between matrix and fine particle and also propagated through pre-existing flaws in the coarse particles at room temperature. On the other hand, the crack propagated along the micro-cracks nucleated by debonding or pulling-out of fine particles and also propagated along the interface between matrix and coarse particle even if a pre-existing flaw would be in the particle at elevated temperatures. Nonlinear deformation behavior at elevated temperature would be attributed not only to matrix softening but also to debonding of particles.
