Review on nano‐and microfiller‐based polyamide 6 hybrid composite: Effect on mechanical properties and morphology

Abstract

Polyamide 6 (PA6)-based composites are of evolving interest due to its high strength, wear resistance, and barrier properties. The use of binary composites mostly with nanomaterial and glass fibers has been reviewed and presented in literature. However to obtain a balance of properties like stiffness, toughness, and strength along with cost reduction, ternary composites of PA6 have been designed. To achieve the balance, PA6 blend-based composites, with combination of microfiller/nanofiller or PA6 with combination micro-microfiller, PA6 with microfiller/nanofiller and fiber have been designed. The properties of PA6-based ternary hybrid composites depend on type of dispersed phase used, presence of compatibilizer, type of filler used (nanofiller or microfiller or fiber or hybrid) and combination of fillers used. However, a review in this direction is not available in literature. Here, in this study, an overall understanding of various fillers, dispersed phase, and their combinations can be understood along with the discussion on effect of these on tensile properties and

Effect of in situ fibrillation on polyethylene/poly(ethylene terephthalate)/multiwalled carbon nanotube electromagnetic shielding foams

“…For aerogel [ 4 ] and chemical vapor deposition [ 5,6 ] approaches, the less single yield and poisonous gas make safety and environmental protection difficult. The mechanical approach [ 7,8,9 ] adopts continuous equipment, such as ultralengthy diameter‐ratio extruder [ 10,11 ] and microfoaming injection molding machine, [ 12–14 ] as well as reduces carbon agglomeration, thus satisfying commercial requirements.…”

Toward Largely Enhanced Toughness and Balanced Strength in PA1012/EPDM Blends via Synergistic Effect of Sacrificial Bonds and Network Structure

“…Even though PA/rubber/rigid filler ternary composites have exhibited excellent toughness and strength at the same time, this strategy usually depends on filler dispersion and interfacial regulation significantly, which is typically required complex modification and difficult to control. [ 15 ] In addition, it has been demonstrated that in situ fibrillation technique is another way to improve the impact performance of polymer without sacrificing its stiffness. Kelnar et al.…”

Carbon, Glass and Basalt Fiber Reinforced Polybenzoxazine: The Effects of Fiber Reinforcement on Mechanical, Fire, Smoke and Toxicity Properties

“…Fiber-reinforced polymers (FRP) exhibit unique material properties, specifically high stiffness-to-weight ratios and excellent corrosion resistance, compared to other materials, e.g., metals [ 1 , 2 , 3 ]. In some cases, combustible FRPs can replace non-combustible materials such as steel.…”
