In filled elastomers, the mechanical behavior of the material surrounding the fillers -termed interphasial material-can be significantly different (softer or stiffer) from the bulk behavior of the elastomeric matrix. In this paper, motivated by recent experiments, we study the effect that such interphases can have on the mechanical response and stability of fiber-reinforced elastomers at large deformations. We work out in particular analytical solutions for the overall response and onset of microscopic and macroscopic instabilities in axially stretched 2D fiber-reinforced nonlinear elastic solids. These solutions generalize the classical results of Rosen (1965, “Mechanics of Composite Strengthening,” Fiber Composite Materials, American Society for Metals, Materials Park, OH, pp. 37–75), and Triantafyllidis and Maker (1985, “On the Comparison between Microscopic and Macroscopic Instability Mechanisms in a Class of Fiber-Reinforced Composites,” J. Appl. Mech., 52, pp. 794–800), for materials without interphases. It is found that while the presence of interphases does not significantly affect the overall axial response of fiber-reinforced materials, it can have a drastic effect on their stability.

Fiber Composite Materials

In recent years, the use of natural fibers as reinforcements in polymer composites to replace synthetic fibers like glass is presently receiving increasing attention. Because of their increasing use combined with high demand, the cost of thermosetting resin has increased rapidly over the past decades. However the widely used synthetic fillers such as glass fiber are very expensive compared to natural fibers. Natural fiber-reinforced thermosetting composites are more economized to produce than the original thermosetting. Moreover the use of natural fiber in thermosetting composites is highly beneficial, because the use of natural fibers will be increased. In this study, a bamboo fiber-reinforced thermoplastic composite that made the RTM was evaluated to mechanical properties.

An analytical model was developed to predict the mechanical response to axial loading of oriented fiber composite materials containing a third (dissimilar) material at the fiber-matrix interface. The model approximated the fiber composite geometry by three concentric, but integral, cylinders. Both a totally elastic and an elastic-plastic analysis of the three-component cylinder demonstrated that transverse stresses, with the signs and magnitudes depending upon the elastic and plastic characteristics of the components, developed during axial loading. Tensile transverse stresses, which could drastically reduce the axial properties of the composite if a brittle layer existed at the interface, were shown to result from various combinations of component properties. The internal stresses predicted for the composite model were verified experimentally by testing three-component composite cylinders of maraging steel-copper-maraging steel and Berylco-copper-Berylco in tension.

Abstract The study focuses on instabilities for fiber-reinforced nonlinearly elastic solids under plane deformations. The plane of deformation contains the fiber reinforcement. In particular, fiber kinking and fiber debonding instabilities in fiber-reinforced composite materials are examined in terms of the anisotropic character of the material models. The material models consider simultaneously the material anisotropy and the nonlinear performance of the fiber reinforced materials. Fiber kinking is captured under fiber compresion. Fiber debonding is captured under shearing deformations in the fiber direction.

In this study, the effect of adding nanosize additive to glass fiber reinforced composite plates on mechanical properties and surface milling was investigated. In the light of the investigations, with the addition of MWCNTs additive in the composite production, the strength of the material has been changed and the more durable composite materials have been obtained. Slots were opened with different cutting speed and feed rate parameters to the composite layers. Surface roughness of the composite layers and slot size were examined and also abrasions of cutting tools used in cutting process were determined. It was observed that the addition of nanoparticles to the laminated glass fiber composite materials played an effective role in the strength of the material and caused cutting tool wear.
