“…Inoya et al also added PP to rPET to improve the processability, mechanical performance, and degradation temperature of the rPET . Moreover, some inorganic fillers, such as silicon nitride , glass fibers , and nanoclay , have also been used to improve the physical properties of rPET. The combined useful properties of each component in rPET blends and/or composites can lead to the creation of a toughened material with simultaneously improved properties, processability, biodegradability, and utilization.…”

Recycled poly(ethylene terephthalate) (rPET), obtained mainly from postconsumer bottles, was melt-mixed with either poly(butylene adipate-co-terephthalate) (PBAT) or PBAT plus ultrafine wollastonite (5 lm) at different weight ratios on a twin-screw extruder and then injection-molded. Among the five rPET/PBAT blends (10-50 wt% PBAT) evaluated, the 80/20 wt% rPET/PBAT blend exhibited the highest tensile strength and degree of crystallinity, a slight increase in the tensile strain, and a remarkable increase in the melt flow index, but a lower tensile modulus and thermal stability with respect to the neat rPET. This blend was subsequently filled with four loading levels of wollastonite (10-40 wt%), where the tensile properties (modulus, strain at break, and strength) and thermal stability of the blend were all improved by the addition of wollastonite in a dose-dependent manner. Based on differential scanning calorimetry analysis, the crystallinity of rPET in the rPET/PBAT/wollastonite composites decreased in the presence of wollastonite, accompanied with a noticeable increase in the glass transition, cold crystallization, and crystallization temperatures, but only a slight change in the melting temperature was noted compared with those of the neat 80/20 wt% blend. Moreover, the addition of wollastonite at 30 wt% or higher showed a strong reduction in the melt dripping of the composites during combustion. J. VINYL ADDIT. TECHNOL., 00:000-000, 2015.

“…Karsli et al 3 investigated the effects of SGF-reinforcement on the properties of post-consumer polyethylene terephthalate/poly(ethylene naphthalate) (PET/PEN) blends. Composites of post-consumer PET with SGFs has been used to improve the mechanical and thermo-mechanical properties of post-consumer PET [4][5][6][7] . The blending of post-consumer PET with engineering thermoplastics, such as poly(butylene terephthalate) (PBT) 8 , polycarbonate (PC) 9 and polyamide 66 (PA66) [10][11][12] , is another strategy that has been used to improve the properties of post-consumer PET.…”

Blends of bottle-grade post-consumer polyethylene terephthalate (PET) and virgin polyamide 66 (PA66), over the complete composition range, and corresponding short glass fiber (SGF) reinforced composites were investigated. These materials were compounded in a twin-screw extruder and injection molded as standard specimens. Morphological investigation of the composites revealed that the short glass fibers have a good size distribution and are homogenously dispersed within a polymeric matrix. The PET/PA66/SGF composites showed good mechanical performance in flexural, tensile and impact tests demonstrating that the addition of SGFs to PET/PA66 blends is an interesting approach to obtaining new thermoplastic composites. In addition, this represents a potential application for post-consumer PET, an abundant and cheap material, in the well-established market of PA66/SGF composites, which are widely used in technical parts requiring high mechanical and thermal properties.

“…Likewise, the flexural modulus of POM/kenaf (70/30) increased by nearly 30% from 2.2 GPa to 3.3 GPa compared to neat POM. The results clearly show the influence of hybridization where PET fibre significantly improved the flexural moduli of the composites [25,26]. The flexural modulus of continuous POM/kenaf (70/30) hybrid composite increased by approximately 29% compared to neat POM as illustrated in Fig.…”

The challenges of improving the mechanical properties of natural fibre composites cannot be over emphasized due to fibre geometry, poor fiber distribution in the matrix, the hydrophilic nature of natural fibers and poor fibre-matrix interfacial adhesion. The primary objective of this research is to study the influence of fibre length on mechanical properties of kenaf/PET fibre reinforced POM and to study the effect of hybridization on mechanical properties of the composites. The composites were produced by compression molding and subsequently subjected to tensile, flexural and impact tests according to their respective ASTM standards. The tensile strength of short POM/kenaf/PET (80/10/10) hybrid composite dropped by approximately 33% from 61.8 MPa to 41.3 MPa compared to neat POM. However, the tensile strength of continuous POM/kenaf composites increased significantly by approximately 127% and 107% for 70/30 and 80/20 compositions compared to neat POM. The flexural moduli of short POM/kenaf/PET (70/15/15) hybrid composite and continuous POM/kenaf (70/30) composite improved by approximately 41% and 29%, respectively. The impact strength substantially increased by nearly 161% in continuous POM/kenaf/PET (70/15/15) hybrid composite and 30% in POM/kenaf (80/20) composite. The results show that tensile, flexural and impact properties of the continuous POM/kenaf composites are superior to the short fiber composites, and the influence of hybridization, made a positive impact by enhancing the flexural and impact properties of the composites.
