“…These materials combine ease of processing with a good resistance to corrosion, low specific gravity and high mechanical strength. In conjunction with recyclability, these characteristics enable these materials to be used in automotive applications [1][2][3]. In this context, the low density is of environmental interest because it relates directly to the amount of fuel a vehicle consumes and the quantity of CO 2 it emits.…”

“…PA6 is a high performance engineering thermoplastic used in electrical/electronics, automobile, packaging, textiles and consumer applications. However, limitations in mechanical properties, the low heat deflection temperature, high water absorption and dimensional instability of pure PA6 have prevented its wide range applications in load bearing applications such as under-the-hood automotive applications [3].…”

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.

“…In many industries, there has recently been a drive to replace heavy metallic components with lightweight composite structures. A prime example of this trend is seen in the automotive and aerospace industries where rising fuel costs, combined with rising pressure due to ever stricter fuel efficiency regulations, have prompted companies to pursue lightweight composite options . In addition to having high mechanical strength the composites must also be resistant to adverse conditions within their typical operating environments, such as high temperatures and chemical attacks.…”

Recently, in many industrial fields, there has been a drive to replace traditional metallic components with high strength polymer composites in the interest of reducing weight. Polyamide 6,6 (PA66) is a high strength thermoplastic and the behavior can be further enhanced by the addition of reinforcing fillers. Here, PA66 matrix has been reinforced with chopped glass fiber as well as hybrid composites containing both glass fiber and rubber particles. First, a baseline characterization of the mechanical properties is presented followed by a report on the thermal transitions, melting, crystallization, and glass transition, for the composite and pure materials. It is found that the filled samples show lower degree of crystallization and that the glass filled samples show lower crystallization and melting temperatures. Additionally, it was found that the glass reinforced samples led to a decrease in the glass transition temperature (Tg) while higher testing frequencies corresponded to an increase in Tg. Finally, it was demonstrated that the glass filled compounds were able to better retain their mechanical properties at high temperatures relative to the unreinforced materials. POLYM.
