Study of injection molded microcellular polyamide‐6 nanocomposites

Abstract: This study aims to explore the processing benefits and property improvements of combining nanocomposites with microcellular injection molding. The microcellular nanocomposite processing was performed on an injection‐molding machine equipped with a commercially available supercritical fluid (SCF) system. The molded samples produced based on the Design of Experiments (DOE) matrices were subjected to tensile testing, impact testing, Dynamic Mechanical Analysis (DMA), and Scanning Electron Microscope (SEM) analyse… Show more

“…The weight reductions for high, medium, and low shot sizes were 23, 20, and 12%, respectively. This result was also observed by Kharbas and Ming from previous experiments [2,3]. Figures 2-4 display the effects of the three different percentages of core-shell rubber and processing parameters on tensile strength.…”

“…The foam morphology and properties greatly depend on the inclusion of nanoparticles. It has been reported that nanoparticles exhibit improved nucleation efficiency in the polymeric foaming processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. With a low particle loading, microcellular foams with improved uniformity in foam morphology can be produced.…”

“…On the contrary, traditional thermoplastic foams, especially those generally considered as the insulation materials, are less attractive for these applications due to their inferior mechanical strength, poor surface quality, and low thermal and dimensional stability. In light of this, using nanoparticles to reinforce polymer foams has gained particular attention lately [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The foam morphology and properties greatly depend on the inclusion of nanoparticles.…”

“…In general, microcellular nanocomposite foams have higher tensile strength but lower impact strength than their neat resin counterparts. The effect of the nano-clays on the mechanical properties is also related to the weight reduction [16]. The addition of clay into polymer can create more nucleation sites for foaming and can produce smaller cell sizes as compared to the neat polymer.…”
