“…The polyamide-6/glass fibre/ 3wt.% SiO 2 enhanced mechanical properties showed preferred failure modes dominated by delamination during dynamic crashing. In general, it can be said that integration of secondary nanofillers is a positive means to enhance the mechanical properties of PA composites as long as the material 14 designer is conscious of the filler selection as well as the nanofiller weight percentage level which do play a crucial role in final desired properties.

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.

“…However, it is very difficult for the hydrophilic montmorillonite to be exfoliated and well-dispersed in a hydrophobic polymer matrix. Therefore, two main objectives for modification are: to expand the interlayer space of the clay, allowing large polymer molecules to enter into the interlayer space, and to improve the miscibility of clay with the polymer, thereby achieving a good dispersion of clays in the polymer matrix (Zhao et al, 2010). Several methods have been developed to produce clay/ polymer nanocompósitos (Dubois,2000).…”

“…The polyhedral oligomeric silsesquioxanes (POSS) nanoparticles are relatively new promising materials to reinforce, modify and stabilize the polymers because of their flexible chemical and physical hybrid properties [18][19][20][21][22]. POSS are organic/inorganic hybrid materials with an empirical formula of (RSiO 1.5 ) n where n is greater than 4 (generally 8).…”
