“…In fact, these results are also in agreement with the outcomes of the tensile and flexural tests previously described. Several other works have previously reported improvements on the impact properties of green composites with PLA using various epoxidized oils, such as epoxidized soybean (ESO) [55], linseed (ELO) [19], palm (EPO) [57] and jatropha (EJO) oils [36]. Yet, the improvements were modest in comparison with the results obtained in the present study.…”

“…A further increase in the additive content does not cause any significant upgrade on the impact resistance, most likely because after that threshold, the ELO molecules start to interact more with themselves than with cellulosic fibers or even with the PHB or PLA [55]. It is worth mentioning that the use of ELO in the present work brings Several other works have previously reported improvements on the impact properties of green composites with PLA using various epoxidized oils, such as epoxidized soybean (ESO) [55], linseed (ELO) [19], palm (EPO) [57] and jatropha (EJO) oils [36].

Green composites made of bioplastics reinforced with natural fibers have gained considerable attention over recent years. However, the use of natural fibers in composites usually compromise some key properties, such as the impact strength and the processability of the final materials. In the present study, two distinct additives, namely an epoxidized linseed oil (ELO) and a sugar-based surfactant, viz. GlucoPure® Sense (GPS), were tested in composite formulations of poly(lactic acid) (PLA) or poly(hydroxybutyrate) (PHB) reinforced with micronized pulp fibers. Both additives showed a plasticizing effect, which led to a decrease in the Young’s and flexural moduli and strengths. At the same time, the elongation and flexural strain at break were considerably improved on some formulations. The melt flow rate was also remarkably improved with the incorporation of the additives. In the PHB-based composites, an increment of 230% was observed upon incorporation of 7.5 wt.% ELO and, in composites based on PLA, an increase of around 155% was achieved with the introduction of 2.5 wt.% GPS. ELO also increased the impact strength to a maximum of 29 kJ m−2, in formulations with PLA. For most composites, a faster degradation rate was observed on the formulations with the additives, reaching, in the case of PHB composites with GPS, a noteworthy weight loss over 75% under burial testing in compost medium at room temperature.

“…Both durian fiber and the fiberboard with optimum mixing ratio and pressing pressure were characterized in terms of the following: FESEM-EDX and optical microscope for surface morphology, HXRF for elemental analysis, FTIR analysis, and TGA for thermal analysis. For FESEM analysis, specimens were magnified 500x, 1000x, and 2000x [12,32]. The accelerating voltage of FESEM was set at 2.0 kV, beam current at 86 pA, EDS accelerating voltage at 15.0 kV, and beam current at 0.69 nA.…”

Medium-density fiberboard (MDF) was developed from Durio zibethinus (durian) husk using urea formaldehyde (UF) as a binder. The output will be applied as an automotive panel, realigning the conventional application of MDFs. Fiberboards were prepared at varying mixing ratios and pressing pressure to determine the optimal conditions. The fibers and optimized fiberboard were characterized in terms of surface morphology, elemental analysis, FT-IR analysis, and thermal stability. Moreover, the physical and mechanical properties of fiberboard were also studied. Results showed that the fiberboard was optimized at a 1:4 fiber-to-resin ratio by mass and press pressure of 640 kPa. It has a density of 0.71 g/cm3, thickness swelling (TS) of 3.33%, water absorption (WA) of 62.44%, internal bond (IB) of 2.85 MPa, modulus of elasticity (MOE) of 3008.06 MPa, and modulus of rupture (MOR) of 22.25 MPa. These were compared against properties of commercial MDF based on American National Standards Institute (ANSI) specifications (0.5≤D≤1, TS≤15%, IB≥0.6 MPa, MOE≥2500 MPa, and MOR≥22 MPa). Based on the results, the optimized fiberboard demonstrated high potential for commercial application in the automotive industries.
