“…The mechanical properties of multi-phase materials can be generally considered as a function of the respective contribution of each phase [27]. The situation is more complicated with regard to the wear behavior, since some chemical reactions and physical interactions among these phases may occur during the wear process and dominate the wear performance of polymer composites.…”

Study on friction and wear behavior of polyphenylene sulfide composites reinforced by short carbon fibers and sub-micro TiO particles. Composites Science and Technology, Elsevier, 2009, 68 (3-4) AbstractPolyphenylene sulfide (PPS) composites filled with short carbon fibers (SCFs) (up to 15 vol.%) and sub-micro-scale TiO 2 particles (up to 7 vol.%) were prepared by extrusion and subsequently injection-molding. Based on the results of sliding wear tests, the tribological behavior of these materials was investigated using an artificial neural network (ANN) approach. A synergistic effect of the incorporated short carbon fibers and sub-micro TiO 2 particles is reported. The lowest specific wear rate was obtained for the composition of PPS with 15 vol.% SCF and 5 vol.% TiO 2 . A more optimal composition of PPS with 15 vol.% SCF and 6 vol.% TiO 2 was estimated according to ANN prediction. The scanning electron microscopy (SEM) observation revealed that this hybrid reinforcement could be interpreted in terms of a positive rolling effect of the particles between the two sliding surfaces, which protected the short carbon fibers from being pulled out of the PPS matrix.

“…Fiber reinforced composites can be explained as the strength of fibers in fibrous composites exceeds considerably the strength of the matrix. Fibers such as short aramid (AF), glass (GF) or carbon (CF) fibers are used in order to increase the creep resistance and the compressive strength of the polymer matrix system used [6]. The addition of fibers is to ensure the strength of the material while the matrix helps to keep the shape of the composite.…”

Abstract. The epoxy/glass fiber/organo-montmorillonite (OMMT) nanocomposites were prepared by hand lay up method. In the previous work, the flexural and morphological properties of the epoxy/glass fiber/OMMT were studied. In this work, the epoxy nanocomposites were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and water absorption tests. The exfoliation of OMMT in epoxy/glass fiber nanocomposites was detected by XRD. DSC results showed that the glass transition temperature (Tg) of epoxy was increased slightly in the presence of OMMT. Water uptake of epoxy was reduced by the addition of glass fiber and OMMT. The decrease of water absorption in epoxy is attributed to the increasing of tortuosity path for water penetration in the epoxy composites by the hybrid of glass fiber and OMMT.

“…Moreover, comparing to unfilled polymers, fiber-reinforced polymer matrix composites provide an essential improvement of different mechanical properties [1]. Considering tribological properties, the studies reported in [2] showed that the application field of polymer matrix composites with micron-sized functional fillers could be extended by additionally incorporating a small fraction of inorganic nanoparticles.…”
