The current study focuses on treated and untreated Musa acuminate peduncles fiber (MAPFs) reinforced polyester composites for lightweight application. For the first time, the impact of alkali treatment and fiber weight fraction on the mechanical, thermal, and morphological characteristics of MAPFs bonded polyester composites have been examined. The fiber from 0 to 25 wt% (alkalitreated and raw) was reinforced with polyester matrix in compression/hand lay method. At 20 wt% of fiber, significant improvements in tensile strength (40.97 MPa), tensile modulus (1.18 GPa), impact (72.68 J/m), flexural strength (63.54 MPa) and flexural modulus (2.16 GPa) were recorded, whereas beyond reduces the properties. Following tensile testing, the fractured cross-sections of the composite were investigated using scanning electron microscope, which demonstrated that the alkali-treated MAPFs reinforced polyester composite had fewer voids and better fiber bonding. Thermogravimetric and atomic force microscopy analysis show that alkali-treated MAPFs are a viable reinforcement for polyester matrix due to higher degradation temperature and surface roughness observations.

“…Recently it was proved that specific mechanical properties (when divided by density) of the natural fiber reinforced composite were comparable with synthetic fibers, which created a new path to be used for various industrial applications such as panels, door parts, clutch plates, seat cover plates, dashboards, and backrests [119,120]. Table 3 tabulates the mechanical properties of new sustainable composites reinforced with various bast fibers [121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139]. The use of these biodegradable lignocellulosic fibers of plant bast origin has been an ecological and economical choice and, bast-based fibers are inexpensive and available in abundance around the world (figure 5).…”

This systematic review focuses on the exploration and advancement of sustainable and eco-friendly polymer composite materials derived from bast fibers. Bast fibers, obtained from the phloem of certain plants like flax, hemp, jute, and kenaf, represent a renewable and environmentally benign resource. Their integration into polymer based composites has gained significant attention due to the growing environmental concerns and the need for sustainable material development. The importance of this study lies in its comprehensive examination of bast fibers as viable alternatives to the synthetic fibers in polymer composite materials. By harnessing the natural strength, light weight, and biodegradability of bast fibers, this review contributes to the creation of materials that are not only environmentally sustainable but also possess enhanced mechanical properties suitable for various industrial and domestic applications.

Application of natural fiber-polymer composites (NFPCs) in different industrial applications provides competitive edge due to their lightweight, higher specific mechanical properties than glass fibers, sustainability, and lower cost involved in production. There are certain challenges associated with natural fibers and their reinforcement in composites such as poor bonding between the fibers and matrix due to their contradictory nature of characteristics, moisture absorption, lower thermal properties, and poor interfacial adhesion between the natural fiber and polymer matrix. The challenges involved in NFPCs need to be overcome to produce materials with relatively equivalent properties to those of conventional composites and other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and their sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs, is needed for better understanding of the behavior of NFPCs. This work provides the information and holistic view of natural fiber-reinforced composites based on the results obtained from modification techniques, with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix, and enhanced mechanical and thermal properties in the composites.
