“…Today, a wide variety of biobased and/or biodegradable polymers with potential use at an industrial scale can be obtained from renewable resources . These polymers could be used as environmentally friendly solutions as against conventional petroleum‐based and non‐biodegradable polymers in blend formulations, disposable products, medical devices, packaging, green composites, etc. It is worth noting the increasing use of aliphatic polyesters, polysaccharides and protein‐derived polymers .…”

“…TS and TM of SMPC were found 70.1 MPa and 4.16 GPa, respectively. [11] In contrast, the double layer-based composite, DMPC, may get additional shear strength from both layers and PLA matrix. On the other hand, the highest TS (81.1 MPa) and TM (5.23 GPa) was shown by DMPC.…”

Three different processing techniques, extrusion, injection, and compression, were followed to fabricate poly (lactic acid) (PLA) and Moringa oleifera fiber (MOF) based composites. Chopped fibers of length 3-5 mm were used for the extrusion followed by injection molding, whereas long-length fibers (~100 mm) were used for compression molding process. For compression molding, long-length fibers were spread in single and double layers. The interfacial shear strength of the composites was evaluated by fiber pull-out testing. Composites were characterized for fracture behavior and mechanical properties. Additionally, surface morphology was also observed by scanning electron microscopy, whereas crystalline properties were evaluated by X-ray diffraction analysis. Analyses revealed that compression molding with double layers of long-length fibers reinforcement showed better properties than other samples. Tensile strengths of extruded and compression processed samples (double-layered) were 75.5 and 81.1 MPa, which are approximately 33% and 44% higher respectively than neat PLA (56.5 MPa). The crack generation of PLA during applied load was observed and found eliminated for the double-layered sample processed via compression molding. It was found that compression molding with double layer can be considered as easy and less time-consuming method for composite preparation, with nearly 8 wt.% of less fiber consumption compared with extrusion/injection molding.

“…[5] Consequently, the development of new green composites has been receiving increasingly attention of researchers and engineers seeking an alternative capable to meet good mechanical properties and low cost with renewability and recyclability. [6] Natural fibers can be viable alternatives to synthetic fiber reinforced composites in several applications, such as in automotive industry, where natural fibers can promote environmental and economic benefits. The automotive market has progressively increased the utilization of natural fiber reinforcement to diminish the fabrication costs and, simultaneously, maximize weight reductions which results in energy saving.…”

The use of natural fibers as reinforcement in composites has received much attention due mainly to environmental issues and because of their interesting properties. The development of new methods for production of thermoplastic composites with natural fibers is of great interest for several sectors in industry. In this work, composites of polypropylene and raw cotton fabric are fabricated by hot pressing alternating layers of polypropylene films and cotton fabric to produce a long fiber oriented composite material. Five combinations with different number of reinforcement and matrix layers are prepared, leading to composites with more than 50% of fiber in volume. Characterization of the composites showed a great enhancement on mechanical properties (85% on elastic modulus and 90% on tensile strength) with a density decrease of around 15%. The braided nature of the cotton fiber provided good adhesion to the matrix through mechanical anchoring, as is observed by SEM. This enabled increased thermal stability and an increase in the storage modulus determined by DMA in the rubbery plateau. The good mechanical properties were explained by the mechanical anchorage of fiber matrix, since PP resin is forced to flow through the fibers of the raw cotton fabric. The resultant material is more resistant, lighter, and stiffer composed of approximately 50% of materials derived from renewable sources.
