“…Besides, they showed that there are a lot of hole and phase separations in blend morphology for 90/10 composition. This has proven to be incompatible between PLA and PC at the 90/10 ratio . In contrast, in our study where PLA and PC were blended at 50/50 ratios, there were no gaps and limits in the blend (Figure A) and interactions of two polymers on the breaking surface were found to be very good.…”

“…This has proven to be incompatible between PLA and PC at the 90/10 ratio. [31] In contrast, in our study where PLA and PC were blended at 50/50 ratios, there were no gaps and limits in the blend ( Figure 6A) and interactions of two polymers on the breaking surface were found to be very good. From this result, it can be said that the PC polymer is well coated with PLA and exhibits a more harmonious behavior than 90PLA10PC.…”

“…It has been observed that tensile strength values have been increased with the addition of GF in increasing loading ratios. Coban et al in their study, reinforced 10% GF to the 90:10 PLA/PC blend and showed that the tensile strength value increased from 57.78 to 74.48 MPa . In the case of a 50:50 PLA/PC, the 10% GF addition blend increased the tensile strength value by 25% compared to 90:10 PLA/PC.…”

“…The tensile strength values of PLA, PC, PLA/PC blend, and GF reinforced composites are given in Figure 1. As [31] In the case of a 50:50 PLA/PC, the 10% GF addition blend increased the tensile strength value by 25% compared to 90:10 PLA/PC. The highest tensile strength value was determined as 110.2 MPa in 50:50 PLA/PC composite containing wt%30 GF.…”

This study aims to investigate the thermal, mechanical, and flammability properties of glass fiber (GF) reinforced PLA/PC composites. PLA/PC (50:50) blend was compounded and used as the control sample. Loading levels of GF were altered as 5, 10, 15, and 30 wt%. All composites were produced in a microcompounder and subsequently molded by injection molding. The properties of the composites were investigated by limiting oxygen index (LOI), tensile test, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscope, and cone calorimetry test. The maximum tensile strength value was observed for 30 wt% GF reinforced composite as 110.18 MPa. Similar initial degradation temperatures were obtained for the composites compared to the PLA. The maximum LOI value was determined as 23.1 for 30 wt% GF reinforced PLA/PC among the produced composites. Besides, it is observed that the addition of GF significantly decreased the total heat release rate.

“…In addition, residual amounts ranging from 1–5 wt.% were reported with fiber reinforcement added in different proportions. 45 When the values were taken into consideration, it was found that the increase of the PC amount had more effect on the decomposition end temperature than the decomposition start temperatures. The char residual values of the composites generally vary proportionally to the fiber loading level.…”

Poly (Lactic Acid) (PLA)/Polycarbonate (PC) blend has gained much attention as a bio-based polymeric material in various industrial fields. This study aims to improve the properties of PLA/PC blend reinforced with glass fiber (GF) and carbon fiber (CF) mixture to be produced for industrial use. For this purpose, 50PLA/50PC blend was prepared and used as a control sample. Then, 30% by weight CF and 30% GF were added to the matrix separately. To examine the effect of the use of CF and GF together, the composites were prepared as a mixture form of fibers by adding 5-10-15% CF and 5-10-15% GF, respectively, to the control blend in pairs. All composites compounded with the laboratory-scale twin-screw mini extruder and molded by injection molding. The effects of using synthetic fiber mixture were evaluated in terms of the mechanical, thermal and flammability properties. Differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), tensile test, scanning electron microscopy (SEM), limiting oxygen index (LOI), heat release rate (HRR) test were carried for the characterization of composites. The highest tensile strength values and maximum % crystallinity values were obtained for the 15CF/15GF fiber mixture containing PLA/PC composite as 113.7 MPa and 21.4, respectively. CO yield (COY), HRR, and total heat release rate were reduced significantly by using synthetic fibers and fiber mixture.
