Natural fibers have been approved as an excellent alternative for traditional reinforcements in polymer composites. However, the main disadvantage of natural fibers as reinforcements is their poor interaction with polymeric matrices due to their hydrophilic nature. In order to improve their compatibility as composite reinforcement, surface treatments are required. Silane treatment has been widely used to modify hygroscopic properties of natural fibers. In this study, a new method of silane treatment has been developed without the prehydrolysis and curing/dehydration of silanol groups. To do so, flax fibers were modified through 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO)-mediated oxidation followed by direct application of the amino-silane. The fiber/matrix interfacial adhesion was examined by measuring interlaminar shear strength. Thermogravimetric analysis and dynamic mechanical analysis were performed to study the thermal resistance and thermomechanical properties of the composites. The results revealed that fiber/matrix adhesion was improved in the oxidized silanized fiber composite. In addition, water absorption was significantly reduced (20%) in the oxidized silanized fiber reinforced composite compared with the as-received one.

“…Ultimate tensile strength, tensile modulus and interlaminar strength was increased by 6%, 13% and 20% respectively when compared to the raw composites. Coating the fibers also allowed the decrease in water absorption by more than 10% in comparison with raw composites and their protection during conditioning, preserving their mechanical properties [ 61 ]. With the aim of improving flame retardancy, a thin coating of polydopamine adhesive was used to protect hot compression molded composites.…”

Multiple environmental concerns such as garbage generation, accumulation in disposal systems and recyclability are powerful drivers for the use of many biodegradable materials. Due to the new uses and requests of plastic users, the consumption of biopolymers is increasing day by day. Polylactic Acid (PLA) being one of the most promising biopolymers and researched extensively, it is emerging as a substitute for petroleum-based polymers. Similarly, owing to both environmental and economic benefits, as well as to their technical features, natural fibers are arising as likely replacements to synthetic fibers to reinforce composites for numerous products. This work reviews the current state of the art of PLA compounds reinforced with two of the high strength natural fibers for this application: flax and jute. Flax fibers are the most valuable bast-type fibers and jute is a widely available plant at an economic price across the entire Asian continent. The physical and chemical treatments of the fibers and the production processing of the green composites are exposed before reporting the main achievements of these materials for structural applications. Detailed information is summarized to understand the advances throughout the last decade and to settle the basis of the next generation of flax/jute reinforced PLA composites (200 Maximum).

“…Polymer composites, by incorporating different types of fillers in polymer matrix, offer an effective approach to tailor the material properties to achieve a high performance/cost ratio. Natural fibers, such as flax fiber, [2,3] kenaf fiber, [4] coir fiber, [5] and bamboo fiber, [6,7] have been used as a reinforcing or cost reducing filler to make sustainable eco-friendly PLA biocomposites. Wood fiber (WF), a type of natural fiber, has been widely used to make wood-plastic composites (WPC) [8][9][10][11][12][13][14][15][16][17][18] or hybrid composites, [19][20][21] because WF offers advantages such as low cost, low density and less wear to processing equipment.…”

Polylactide (PLA), derived from bioresources, is an environmentally friendly plastic which has attracted tremendous interests in both academia and industry. This study investigates the feasibility of direct injection molding of PLA/wood-fiber composites and their mechanical and longitudinal shrinkage behaviors under different molding conditions. To understand the processingproperty relationship of the thermally sensitive composites, response surface methodology was applied to study the effects of molding parameters, as well as their interacting effects, on the tensile strength and the longitudinal shrinkage of the composites. Melt temperature, packing pressure, and injection speed were chosen as the molding parameters studied. The statistical models were validated through confirmation experiments. The predicted values are in agreement with experimental data, and the average prediction accuracy is more than 95% for both tensile strength and longitudinal shrinkage. The models would not only improve our understanding of the tensile strength and shrinkage behaviors, but also can be used to help tooling design and select a proper processing window to maximize the tensile strength while achieving the desired longitudinal shrinkage.
