Highlights• Relation between the filler volume fraction/particle size & mechanical properties;• Relation between wear resistance and mechanical properties and the contact media;• Wear performance comparison of micro and nanofiller in: sliding and abrasive media. AbstractThe addition of ceramic reinforced material, SiC particles, to resin matrices, results in the improvement of the overall performance of the composite, allowing the application of these materials as tribomaterials in industries such as: automotive, aeronautical and medical. Particle-reinforced polymeric composites are widely used as biomaterials, for example as dental filler materials and bone cements.These reinforced composites have improved mechanical and tribological performance and have higher values of elastic modulus and hardness, and also reduce the shrinkage during the polymerization compared with resin matrices. However, the effect of the filler level in mechanical and tribological behaviour is not quite understood.The aim of this work is to determine the influence of the particle volume fraction and particle size in the wear loss of the composites and their antagonists. Reciprocating wear tests were conducted using a glass sphere against resin polyester silica reinforced composite in a controlled medium, with an abrasive slurry or distilled water. For 6 μ m average particle dimension, seven particles contents were studied ranging from 0 % to 46 % of filler volume fraction (FVF). Afterwards, filler volume fractions of 10 % and 30 % were selected; and, for these percentages, 7 and 4 average particle dimensions were tested and were evaluated regarding their wear behaviour, respectively. The reinforcement particle dimensions used ranged from 0.1 μ m to 22 μ m with the 10 % filler fraction, and for 30 % of filler content the range extended from 3 μ m to 22 μ m. The results allow us to conclude that in an abrasive slurry medium the composite abrasion resistance decreases with the increase of the particle volume fraction, in spite of the accompanying rise in hardness and elastic modulus. With constant FVF, and abrasive slurry, the composite wear resistance increases with increasing average particle dimension. In a distilled water medium and with several FVF values, the minimum wear was registered for a median particle content of 24 %. In this medium and with constant FVF the highest wear resistance occurred for average reinforcement particles of 6 μ m. The removal mechanisms involved in the wear process are discussed, taking into account the systematic SEM observations to evaluate the we...

“…Incorporating inorganic nanoparticles into organic polymers will improve the mechanical, thermal, optical and barrier properties. Commonly used inorganic additives include clay [1,2], SiO 2 [3][4][5], carbon nanotubes [6,7], and carbon nanofibers [8], among others. Polyaniline (PANI) is a potential material for commercial applications owing to its facile synthesis, relatively low cost, environmental stability, good processability, and unique optical, electrical and electrochemical properties [9,10].…”

Abstract.In this study, we compare the effects of aniline-modified mesoporous silica (AMS), raw silica (ARS) and nonmodified raw silica (NRS) particles on the physical properties of as-prepared polyaniline (PANI)-silica mesocomposites (PSM) and nanocomposites (PSN) and PANI-raw silica (PRSN) membranes. First, aniline-modified silica particles were synthesized by a conventional base-catalyzed sol-gel reaction of tetraethyl orthosilicate (TEOS) in the presence or absence of N-[3-(Trimethoxysilyl) propyl]aniline (PAPTMS). Subsequently, PSM, PSN and PRSN materials were prepared through in situ oxidation polymerization reaction of aniline monomer in the presence of AMS, ARS and NRS particles. It should be noted that all the properties of PSM membranes improved substantially from those of PSN and PRSN. For example, upon 3 wt% loading of AMS particles, 10, 25, 10, and 85% increases in thermal stability, mechanical strength, surface hydrophilicity and gas permeability were observed for PSM membranes, respectively, as well as more than 45% reduction in the thermal conductivity.

Uses of natural wood/PVC composite products are increasing in various fields of construction and in building materials applications. This present work aimed to develop wood/PVC hybrid composite materials by incorporating synthetic fibers, namely E-glass, S-glass, and carbon fibers. Three different wood flours were also considered, including Xylia kerrii Craib & Hutch, Hevea brasiliensis, and Mangifera indica Linn. The mechanical, morphological, and wear properties were of interest. The results suggested that the addition of synthetic fibers significantly improved the flexural properties of wood/PVC composites, but only slightly affected their specific wear rate values, this effect being most pronounced with the incorporation of carbon fiber and when tested at longer sliding distance. The influence of different wood types showed no definite trend on the specific wear rates of the wood/PVC hybrid composites. Among different counterface materials used, a sandpaper counterface resulted in the highest specific wear rate, which involved a two-body abrasion mechanism. The results of this work indicated that S-glass fiber and XK wood were most suitable for co-reinforcing the wood/PVC composites in terms of wear-resistant applications.
