Natural renewable materials can play a big role in reducing the consumption of synthetic materials for environmental sustainability. Natural fiber-reinforced composites have attracted significant research and commercial importance due to their versatile characteristics and multi-dimensional applications. As the natural materials are easily rotten, flammable, and moisture absorbent, they require additional chemical modification for use in sustainable product development. In the present research, jute fibers were treated with rot-, fire-, and water-retardant chemicals and their corresponding polymer composites were fabricated using a compression molding technique. To identify the effects of the chemical treatments on the jute fiber and their polymeric composites, a Fourier transformed infrared radiation (FTIR) study was conducted and the results were analyzed. The presence of various chemicals in the post-treated fibers and the associated composites were identified through the FTIR analysis. The varying weight percentage of the chemicals used for treating the fibers affected the physio-mechanical properties of the fiber as well as their composites. From the FTIR analysis, it was concluded that crystallinity increased with the chemical concentration of the treatment which could be contributed to the improvement in their mechanical performance. This study provides valuable information for both academia and industry on the effect of various chemical treatments of the jute fiber for improved product development.

This paper studies the effects of plain-woven fabrics of jute and cotton, used as reinforcements, on the mechanical properties of composite panels prepared using epoxy and polylactic acid (PLA) resins as matrix materials. Two different composites were prepared in the current study — natural fiber fabrics reinforced thermosetting epoxy resin and the same fabrics reinforced thermoplastic PLA resin. Two methods were used to manufacture these composites. The thermosetting composites were manufactured by impregnating the epoxy resin with the fabrics by hand lamination. On the other hand, the resin film method was used to manufacture the thermoplastic composites. Tensile, compression and 3-point bending tests were performed on the composite panels. The experimental results indicated that the compressive strengths of cotton/PLA and cotton/epoxy composites are approximately equivalent. The jute-based composites exhibited brittle failure in the tensile test. Furthermore, the 3-point-bending break strength of the cotton/PLA composites was higher than that of the jute/PLA composites.

Researches on thermoplastic composites using natural fiber as reinforcement are increasing, but studies of durability over time are scarce. In this sense the objective of this study is to evaluate changes in the properties of polypropylene/bamboo fiber (PP/BF) composite and the influence of the use of coupling agent (CA) in these composites after natural ageing. The PP/BF (70/30 wt) composites and 3% wt CA (citric acid from natural origin and maleic anhydride grafted polypropylene from petrochemical origin) were prepared by using an internal mixer chamber and then injection-molded. The samples were exposed to natural weathering for a total period of 12 months and characterized before and after exposure. All exposed composites experienced a decrease in their properties, however, the use of CA promoted more stability; in mechanical properties, the composites with CA showed lower loss about 23% in Young′s modulus, 18% in tensile stress at break, and 6% in impact strength. This behavior was similar in thermal and physical properties, the result for the CA of natural origin being similar to that of synthetic origin. These results indicate that the use of a CA may promote higher interaction between the fiber and the polymer. In addition, the CAs of organic origin and synthetic origin exhibited similar responses to natural ageing.

Kenaf Fibers

The use of natural fibers at high percentages of loading in thermoplastic composites for the production of sustainable and green materials in consumer goods, furniture, automotive industry and construction industry is emerging. Several studies have been conducted by many researchers to improve the mechanical properties of the fibers and the fiber-matrix interface for better bonding and load transfer especially when high fiber loading is used. The natural fiber hydrophilic properties make the poor interface and poor resistance to moisture absorption when used to reinforce hydrophobic matrices. Therefore, this study investigates the effects of different surface treatment namely magnesium chloride (MgCl2) and sodium hydroxide (NaOH) on the properties of kenaf fiber for different molarities. Morphology using scanning electron microscopy (SEM) and fourier transform infrared (FTIR) spectroscopy and tensile properties of kenaf fibers after different surface treatment are evaluated. Results showed that the treatment on kenaf fibers has removed the hydroxyl group in cellulose and increase the surface roughness which resulted in the improvement of the tensile properties of kenaf fibers as compared to untreated kenaf fibers.

Stiffness Property

In this paper, the stiffness mechanical property of natural fiber reinforced thermoplastic composites is analyzed using composite micromechanical model. Kenaf natural fiber is selected as the reinforcement material in the composites construction while three types of commonly used automotive grade thermoplastic matrices, namely polypropylene, acrylonitrile butadiene styrene and polyamide 6 were selected to be reinforced with kenaf fibers. Their stiffness property was later analyzed using Halpin-Tsai micromechanical model at varying fiber content and fiber aspect ratio conditions. In all cases, theoretical results show that the kenaf reinforced thermoplastic composites stiffness increased linearly as the fiber contents were increased. Apart from that, results also show that the stiffness property also increases as the fiber aspect ratio was increased. Higher final composites stiffness property was also observed as stiffness matrix material is utilized in the composites formulation. The prediction results also provided valuable and quick insight as well as cost effective alternative to composite designers in assessing the stiffness performance of natural fiber composites especially those which are reinforced with thermoplastic matrices compared to conventional experimental technique for automotive product development purposes in addition to identifying the optimal parameter to be put into focus in their composites design to achieve the intended design performance specifications.

Abstract Natural fiber reinforced thermoplastic composites using flax and polypropylene were prepared using compression molding process. Needle punched nonwovens were used as preforms for preparing the composites. Three variables namely fiber weight proportion, areal weight of the mat, and needling density were chosen for the study. Modified Taguchi L18 experimental design with dummy variable was chosen for the study and the effect of the above variables on tensile, flexural, and impact properties of the composites were studied. By altering the fiber weight proportion and areal weight of the mat, tensile and flexural properties improved. An increase in 34% of tensile strength and 40% of flexural strength has been observed. Impact properties of the composites were significantly altered by modifying the process variables. Increasing the needling density led to a decrease in overall mechanical properties of the composites.
