“…Another area that has gained attention is the production of natural fiber filled polymer composites due to easy and abundant availability as byproducts in the form of peels, stalks and fibers from the plants sector after harvesting of crops [8][9][10]. These natural materials/fibers replace the synthetic fillers being added to increase the strength of the commercial synthetic polymers and further making these polymers semi-biodegradable.…”

Polypropylene composites were prepared using natural fibers such as pigeon pea stalk fibers and banana peel. Aerobic biodegradation studies in compost have been carried out as per ASTM with composites prepared where cellulose and polypropylene has been taken as positive and negative reference respectively. Various analytical tools like SEM, TGA, XRD, DSC and Color have been used to study the change after biodegradation in composites. Highest fiber loaded composites i.e. 40 wt% depicted highest biodegradation in comparison to 10 and 20 wt% loading of untreated fiber in polypropylene. In comparison to untreated fiber composites, maximum biodegradation was observed in treated fiber composites with same amount of the fiber loading.

“…For example, by hybridization of natural fibers with any synthetic fibers, although the main benefits of natural fiber composites such as biodegradability, easy handling and processing, and natural resources are being reduced, hybridization can decrease the cost, weight, and environmental concerns produced by the synthetic fiber composites effectively. Several publications scientifically prove that hybridization techniques can enhance the composites’ mechanical, thermal, and dynamic characteristics, such as minimizing water absorption and increasing flame retardancy [ 29 , 30 , 31 ]. The main parameters, which significantly affect the properties of the manufactured hybrid composite products, are as follows [ 27 ]: Materials selection (matrix and fiber), which depend mostly on the proposed application; Preparation technique, which depends on the fiber, matrix, and working conditions (viz.…”

“…Glass, carbon, and aramid fibers are the most frequently used synthetic fibers in composites in varied areas of aerospace, defense, construction, sports, naval, etc. One of these fibers’ benefits over natural ones is that they are independent of growing conditions and can be manufactured with distinct functionalities needed for the proposed application [ 29 , 71 ]. Synthetic fibers are well known for their superior mechanical and thermal properties as compared to natural fibers.…”

Recent Progress in Hybrid Biocomposites: Mechanical Properties, Water Absorption, and Flame Retardancy

Bio-based composites are reinforced polymeric materials in which one of the matrix and reinforcement components or both are from bio-based origins. The biocomposite industry has recently drawn great attention for diverse applications, from household articles to automobiles. This is owing to their low cost, biodegradability, being lightweight, availability, and environmental concerns over synthetic and nonrenewable materials derived from limited resources like fossil fuel. The focus has slowly shifted from traditional biocomposite systems, including thermoplastic polymers reinforced with natural fibers, to more advanced systems called hybrid biocomposites. Hybridization of bio-based fibers/matrices and synthetic ones offers a new strategy to overcome the shortcomings of purely natural fibers or matrices. By incorporating two or more reinforcement types into a single composite, it is possible to not only maintain the advantages of both types but also alleviate some disadvantages of one type of reinforcement by another one. This approach leads to improvement of the mechanical and physical properties of biocomposites for extensive applications. The present review article intends to provide a general overview of selecting the materials to manufacture hybrid biocomposite systems with improved strength properties, water, and burning resistance in recent years.

“…Several researchers have proposed many natural fiber based composites for various engineering applications [2]. Because of their lightweight nature, biocomposites used by the automobile industries enhance their fuel economy [3]. Researchers have also investigated hybrid biocomposites that are made by adding two or more variety of natural fibers in a standard matrix to increase the mechanical properties [4].…”

A novel hybrid composite was developed from natural fibers and the mechanical properties were investigated in this work. The palm sheath and sugarcane bagasse fibres were the natural fibers used and epoxy resin was the matrix. By using compression‐molding machine, various samples were prepared by varying the weight proportions of fibers. The performance of fibers was investigated under untreated and NaOH treated conditions. The tensile properties, flexural properties, hardness, and impact properties were evaluated using ASTM standards. The best sample was determined based on the experimental results. The best sample had the tensile strength of 19.80 ± 0.78 MPa, Young's Modulus of 0.953 ± 0.076 GPa, flexural strength of 28.79 MPa, impact strength of 2 kJ/m2, and the hardness value of 38.02 HD. The best sample was used to develop an automobile dashboard to justify its application.
