“…This can be explained by the fact that a poor interaction between PLA-AC or PLA-WC than PLA-PLA was created in composites. Similar behavior was reported in Kenaf fiber reinforced Floreon composites (Lee et al, 2016).…”

In this work, various microcrystalline celluloses were extracted from apricots shells (AC) and walnut shells (WC) by alkaline treatments combined with hydrogen peroxide blanching. Different composites-based poly (lactic acid) (PLA) and microcrystalline cellulose PLA/AC and PLA/WC were successfully prepared by the cast-solution method with various PLA/AC and PLA/WC ratios. PLA and prepared composites were characterized by tensile test, Fourier transform infrared spectroscopy (FTIR), melt flow index (MFI), thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Results showed an increase in Young’s modulus from 802.6 MPa (PLA) to 1412.9 MPa (10% AC) and to 1145,6 MPa (7% WC) in PLA composites. A decrease in degradation temperature was recorded with increasing microcrystalline cellulose percentage in PLA composites from 354°C (PLA) to 328°C (PLA/10% AC) and 339°C (PLA/10% WC). An enhancement in crystallinity rate was observed after incorporation of the microcrystalline cellulose from 30.42% (PLA) to 37.97% (PLA/7% WC) and 38.47% (PLA/10% AC). Furthermore, the biodegradation was evaluated by a soil burial test. A loss in composites weights of 38% (PLA/7% WC), 13% (PLA/7% AC) and 14% (PLA) was obtained after 12 months within soil burial test. Finally, the presence of MCC extracted from walnut shells in PLA matrix at 7% of content exhibited the best mechanical properties, crystalline structure and biodegradability rate.

“…This phenomenon is associated with the requirement for increased processing temperature and high injection molding speed or forming pressure, which significantly affects the material’s structure and is frequently correlated with incomplete lignocellulosic filler degradation. Generally, the addition of the particle-shaped filler increases the viscosity mentioned above while simultaneously decreasing the wall slip during capillary flow [ 179 , 180 ]. Numerous studies concentrate on the finished properties of composites but frequently neglect to discuss their processing and limitations due to their rheological behavior.…”

Polylactic acid (PLA) is a thermoplastic polymer produced from lactic acid that has been chiefly utilized in biodegradable material and as a composite matrix material. PLA is a prominent biomaterial that is widely used to replace traditional petrochemical-based polymers in various applications owing environmental concerns. Green composites have gained greater attention as ecological consciousness has grown since they have the potential to be more appealing than conventional petroleum-based composites, which are toxic and nonbiodegradable. PLA-based composites with natural fiber have been extensively utilized in a variety of applications, from packaging to medicine, due to their biodegradable, recyclable, high mechanical strength, low toxicity, good barrier properties, friendly processing, and excellent characteristics. A summary of natural fibers, green composites, and PLA, along with their respective properties, classification, functionality, and different processing methods, are discussed to discover the natural fiber-reinforced PLA composite material development for a wide range of applications. This work also emphasizes the research and properties of PLA-based green composites, PLA blend composites, and PLA hybrid composites over the past few years. PLA’s potential as a strong material in engineering applications areas is addressed. This review also covers issues, challenges, opportunities, and perspectives in developing and characterizing PLA-based green composites.

“…e plant fibres have been further classified into more specific groups, according to the location of the fibre obtained on the plant, as shown in Figure 1. Bast fibres are the most widely used among other groups (bast fibres, fruit fibres, grass fibres, root fibres, seed fibres, and leaf fibres) [15][16][17]. Retting is the first extraction process to obtain high-quality fibres.…”

Natural fibres are a gift from nature that we still underutilise. They can be classified into several groups, and bast natural fibre reinforcement in polymer composites has the most promising performance, among others. However, numerous factors have reported influences on mechanical properties of the fibre-reinforced composite, including natural fibre retting processes. In this review, bast fibre retting process and the effect of enzymatic retting on the fibre and fibre-reinforced polymer composites have been discussed and reviewed for the latest research studies. All retting methods except chemical and mechanical retting processes are involving secretion of enzymes by bacteria or fungi under controlled (enzymatic retting) or random conditions (water and dew retting). Besides, enzymatic retting is claimed to have more environmentally friendly wastewater products, shorter retting period, and controllable fibre biochemical components under mild incubation conditions. This review comprehensively assesses the enzymatic retting process for producing high-quality bast fibre and will become a reference for future development on bast fibre-reinforced polymer composites.
