“…The authors have previously shown that nanocomposites may be successfully manufactured using 20 nm diameter silica nanoparticles, and that these particles increase the toughness of the material. Siegel et al [1] obtained an increase of 15 % of the strain to failure filling an epoxy resin with 10 wt. % of nanometric TiO 2 particles.…”

Epoxy (LY-556/HY-951) system filled with modified clay (MC) was synthesized by using mechanical shear mixing with the addition of hardener as tri-ethylene-tetra-amine (TETA). The effect of the fumed silica can be negated by the application of a shear force (e.g. mixing, brushing, spraying etc), allowing the liquid to flow, level out and permit the escape of entrapped air. The reinforcement effects of MC in the epoxy polymer on thermal, mechanical and vibration properties were studied. Curing study shows that the addition MC does not show any effect in the curing behavior of epoxy polymer. Thermogravimetry analysis (TGA) shows enhanced thermal stability for epoxy with MC fillers. The epoxy with MC fillers shows considerable improvement on tensile and impact properties over pure epoxy polymer. SEM studies shows that addition of clay significantly turns the epoxy system from brittle to ductile nature was played instrumental in scaling performance. The improvement in tensile and impact properties of nanocomposites is supported with the fracture surface studies. Epoxy with MC fillers shows enhanced vibration characteristics than that of the pure epoxy polymer. FTIR studies indicated the formation of C-H bonds on the surface of the nanocomposites.

“…Wu et al [16] found that a polyamide-6/clay with 30 wt.% of glass fibre had an enhanced tensile strength of 11% and a tensile modulus enhancement of 42% compared to polyamide-6/ 30wt.% glass fibre. Further, several parameters were demonstrated to have an influence on these mechanical properties (stiffness, modulus) such as interaction between the matrix and the fillers [17], fillers' size [18], fillers' volume fraction [19], and filler's shape [9]. Others advantages are the cost which is low considering that only a small amount of filler is necessary, and the ease of manufacture without need to change the conventional processing conditions in order to manufacture new products [6].…”

Mechanical and impact performance of three-phase polyamide 6 nanocomposites AbstractIn this work, three-phase nanocomposites using multiscale reinforcements were studied to evaluate the influence of nanofillers on static and dynamic mechanical properties at varying temperature conditions. In particular, short-fibres reinforced polyamide 6 (30 wt.%) composites with various weight fractions of montmorillonite (OMMT) and nanosilica (SiO 2 ), manufactured and investigated. Quasi-static tensile properties were investigated at room temperature and also at 65 o C just above the polyamide 6 (PA6) glass transition temperature.The low velocity impact tests were conducted on the manufactured cone-shaped structures to evaluate the crash behaviour and energy absorption capability. The study results shows that the increase of the weight percentage level of OMMT in PA6/glass fibre (30 wt.%) composite made the nanocomposites more brittle and simultaneously deteriorated the tensile properties.SiO 2 nanofiller at 1 wt.% was found to be the optimum ratio for improving tensile properties in silica-based nanocomposites studied. It was further noted that for both types of nanofillers, the crashing behaviour and energy absorption in dynamic properties were improved with increase in nanofillers weight percentage in the composites. The study also shows that the brittleness behaviour of the nanocomposites investigated is associated to the fibre/matrix interaction which is dependent on the nanofiller type and has significant effect on crash modes observed.

“…Recent investigations on inorganic nanoparticles filled polymers demonstrate their significant potential in producing composites with low friction and high wear resistance [1][2][3][4][5]. Compared with the composites incorporated with micro-particles, which are characterized by severe wear resulting from abrasion and particles pull-out, nanocomposites exhibit rather mild wear with fine individual debris acting as lubricant and contributing to material removal by polishing.…”

Abstract.To overcome the disadvantages generated by the loose nano-partilce agglomerates dispersed in polymer composites, a chemical grafting method was applied to modify nano-Si3N4 by covalently bonding glycidyl methacrylate (GMA) onto the particles. The tribological behavior of the epoxy composite filled with nano-Si3N4 or GMA treated Si3N4 (Si3N4-g-PGMA) was studied using a ring-on-block wear tester under dry sliding, and the worn surface of the filled epoxy composite and the surface roughness of the composites after the sliding wear test were investigated by SEM (scanning electron microscopy) and AFM (atomic force microscopy), respectively. In comparison to the composites filled with untreated nano-Si3N4 particles, the composites with the grafted nano-Si3N4 exhibit improved sliding wear resistance and reduced friction coefficient owing to the chemical bonding at the filler/matrix interface.
