“…Likewise, the pre‐treatment of heat and pectinase enzymes also improved a significant amount in the degree of crystallinity from 32.3 ± 0.5 and 35.5 ± 0.7%, respectively. Equally, surface treatments can also help to align the microfibrous structures of cellulose and improve the crystalline nature of the fibers which all present an equivalent contribution to the ramie fibers/PLA biocomposite crystallinity level .…”

“…For thermal properties, the thermal annealing process of ramie fibers reinforced PLA polymer composite involving heat treatment (above its crystallization temperature) is known to impart relaxation capability in PLA‐based polymer systems . Nassiopoulos and Njuguna and Suryangegara et al both reported the improved thermo‐mechanical behavior of reinforced PLA composites with tunable and desirable properties courtesy of heat annealing along with the degree of crystallization.…”

Ramie fibers reinforced poly(lactic acid) (PLA) biocomposites in the recent past have gained a lot of research attention for various applications due to their biodegradability, lightweight and renewable advantages. However, their low thermal stability performances and poor mechanical properties have to this date limited their industrial use. Herein, an approach to solve the two mischiefs is presented, which involved first surface modifying of ramie fibers followed by thermal annealing of the reinforced PLA biocomposites. The resultant biocomposites showed tunable mechanical and thermal resistance properties. These improved properties are ascribed to the improved interfacial bonding of the modified ramie fibers and PLA polymer, courtesy of newly introduced reactive groups onto fibers which were capable of building strong interface bonds between the polymer–fiber boundaries. More still, the thermal stability of the resultant composite is attributed to the thermal annealing condition which provided crystallized PLA molecules upon exposure to high temperatures and the steady cooling responsible for the increased degree of crystallinity in the composites as confirmed from X‐ray diffraction and differential scanning calorimetric data results. Beyond ramie fibers‐based composites reported herein, the presented methodology can also be extended to other natural plant fiber‐based composites. These modifications are capable of providing better PLA/natural fiber‐based composites for automobiles, electronics, and other related domains. POLYM.

“…The mechanical properties of natural fiber-reinforced thermoplastic composites were improved as a result of the incorporation of natural fiber with relatively high strain. Asaithambi et al [138,139] studied the mechanical properties of hybrid banana/sisalreinforced polylactic acid composite. Compared to banana-reinforced Poly(lactic acid) (PLA) and neat PLA, improved mechanical properties were observed in the composites incorporated with high-strength sisal fiber with banana fiber-PLA composite.…”

In recent years, most boat fabrication companies use 100% synthetic fiber-reinforced composite materials, due to their high performance of mechanical properties. In the new trend of research on the fabrication of boat structure using natural fiber hybrid with kevlar/fiberglass-reinforced composite, the result of tensile, bending, and impact strength showed that glass fiber-reinforced polyester composite gave high strength with increasing glass fiber contents. At some point, realizing the cost of synthetic fiber is getting higher, researchers today have started to use natural fibers that are seen as a more cost-effective option. Natural fibers, however, have some disadvantages, such as high moisture absorption, due to repelling nature; low wettability; low thermal stability; and quality variation, which lead to the degradation of composite properties. In recent times, hybridization is recommended by most researchers as a solution to natural fiber’s weaknesses and to reduce the use of synthetic fibers that are not environmentally friendly. In addition, hybrid composite has its own special advantages, i.e., balanced strength and stiffness, reduced weight and cost, improved fatigue resistance and fracture toughness, and improved impact resistance. The synthetic–nature fiber hybrid composites are used in a variety of applications as a modern material that has attracted most manufacturing industries’ attention to shift to using the hybrid composite. Some of the previous studies stated that delamination and manufacturing had influenced the performance of the hybrid composites. In order to expand the use of natural fiber as a successful reinforcement in hybrid composite, the factor that affects the manufacturing defects needs to be investigated. In this review paper, a compilation of the reviews on the delamination and a few common manufacturing defect types illustrating the overview of the impact on the mechanical properties encountered by most of the composite manufacturing industries are presented.

“…Several studies have shown that the mechanical properties of a composite are strongly related to the matrix nature, fiber morphology, aspect ratio, fiber–matrix interface quality, as well as fiber type, concentration and orientation distribution . For example, the fibers in a thin plate tend to orient parallel to the flow direction near the walls due to shear stresses, while they tend to align perpendicular to the flow in the central zone .…”

Mechanical properties prediction of polypropylene/short coir fibers composites using a self‐consistent approach

Short coir fibers composite of thermoplastic polypropylene (PP) matrix was successfully prepared by using a twin‐screw extruder and an injection molding machine. In order to provide a better understanding of the effect of fiber orientation and concentration (2.5, 5, and 10 wt%) on the mechanical properties of short coir fibers reinforced PP, a self‐consistent approach was developed based on a modified Hirsch model by taking the empirical parameter (x) proportionally to the fiber orientation factor (α). Finally, the results are compared with other models (Hirsch and Tsai‐Pagano) and validated with experimental data. Overall, our approach was found to better predict the mechanical results in terms of Young's modulus, tensile strength and torsion modulus. POLYM.
