Abstract :

Recently, recycling of thermoplastic polymers has become an alternative resource in industrial product manufacturing processes. This work is an attempt to enhance the mechanical and nanoindentation behaviors of recycled glass-filled polyamide-12 (RGP) by adding nano-layered silicate (Nanoclay) as reinforced filler. Tensile and nanoindentation tests were conducted to study the effect of various loading levels (0-7 wt%) of nano-layered silicate on the mechanical and nanoindentation behaviors of RGP and its nanocomposites. The recycled glass-filled polyamide-12 (RGP) and recycled glass-filled polyamide-12 reinforced with layered silicate (RGPS) were prepared using a single screw injection moulding technique. The wide angle x-ray diffraction (WAXD) was used to characterize the nanostructure of material and determine the intercalation/exfoliation for layered silicate in RGP matrix. This study has revealed that the layer silicate has a negative effect on the tensile strength and strain (ductility) of RGPS compared with RGP. Moreover, RGFS/5 wt% displayed the lowest tensile strength and strain values, with an average decrease of 54% compared with the RGP sample. However, nanoindentation results showed a remarkable improvement with addition of layered silicate to RGF. The average decrease in the max depth of penetration was 21%, while the average increase in the hardness was 92% for RGPS samples compared with RGP samples. The RGPS/3 wt% sample shows the optimum results in both resistance penetration and hardness of nanocomposites 1100 nm and 0.24 GPa, respectively.
