Thermal and mechanical properties of glass fibre reinforced polyphenylene ether/polystyrene/nylon-6 ternary blends

Abstract

This paper deals with fabrication and characterization of unique polyphenylene ether/polystyrene/nylon-6/glass composites. Compounding of ternary blends with glass fibres was performed using twin screw co-rotating extruder. Test specimens were fabricated by compression moulding and injection moulding. Effect of maleic anhydride, fibre type (chopped and long), fibre content (30 wt. % and 40 wt. %) and fabrication method (compression moulding and injection moulding) on mechanical and thermal properties was studied. Maleic anhydride negatively influenced mechanical and thermal properties. Composites with 40 wt. % chopped fibres showed superior mechanical strength and those with 30 wt. % long fibres showed superior thermal properties, tensile and flexural moduli. Injection moulded specimens exhibited superior mechanical and thermal properties. The composites were studied for moisture content, density, melt flow index, glass transition temperature, thermal degradation temperature and mechanical properties. Interfacial strength was examined using scanning electron microscopy.

Effect of melamine cyanurate on thermal and flame-retardant behaviour of chopped glass fibre reinforced polyphenylene ether/polystyrene/nylon-6

“…%) were 11.11 GPa, 1.28 and 13.93 KJ/m 2 . 9 Addition of MC to PPE/PS/nylon-6/glass increased these properties along with HDT (Table 5). Additionally, MC decreased moisture content, increased density and decreased MFR (due to decreased viscosity) of the specimens.…”

Preparation and Characterization of Glass-Fiber-Reinforced Modified Polyphenylene Oxide by a Direct Fiber Feeding Extrusion Process

“…Li et al [7] reported an average fiber length of 106 µm in their PPO-g-MA/PA6/GF composite, and Vaxman et al [13] reported an average fiber length of 190 µm for a short commercial GF/mPPO composite. However, Hadimani et al [11] reported an average fiber length of 2.28 mm for the direct GF roving yarn feeding to prepare the GF/mPPO composites. Although their processing is similar to the one employed in this study, the difference in the average fiber lengths would result from the different GF content of the pellets for the following injection molding.…”

“…In the majority of the studies, chopped GF was compounded to prepare GF/mPPO composites. To the authors' knowledge, the study reported by Hadimani et al was the only one that explored the direct feeding of GF roving yarns for GF/mPPO composites [11]. The effects of GF content, MA, and various processing methods on the thermal and mechanical properties of GF/mPPO composites were studied.…”

EPDM‐g‐MAH toughened bio‐based polyamide 56 to prepare thermoplastic polyamide elastomer and the performance characterization

“…TPAE can also be polymerized by polyamide and elastomer. The preparation method of polyamide elastomer is divided into solution polymerization method and melt polymerization method 25–28 . Zhao, HK et al used anionic in‐situ polymerization to prepare rubber and nylon composites 29 .…”

“…The preparation method of polyamide elastomer is divided into solution polymerization method and melt polymerization method. [25][26][27][28] Zhao, HK et al used anionic in-situ polymerization to prepare rubber and nylon composites. 29 Based on the above two methods, researchers have exploited and prepared several commonly used polyamide elastomers: PA/NBR TPV, PA/IIR TPV, PA/EPDM TPV, and PA/ACM TPV.…”
