“…Nontraditional fibers are considered one of the arising accoutrements of the present time, and the "sustainability" term is frequently associated with these nontraditional fiber-reinforced composites [74]. It is due to the biocompatibility and ecosustainability of the nontraditional natural fiber-reinforced composites that the utilization of these composites for real-time applications is increasing [75].…”

In recent years, there has been a growing awareness and demand for global sustainability, as well as a mandate for the use of renewable and environmentally sustainable materials and processes. Due to which, massive efforts are being made to develop and nurture the next generation of composite materials that are energy efficient, environmentally friendly, and biodegradable. Light weight, lower coefficient of thermal expansion, and comparable tensile strength exhibited by natural fibers render them the choice for use in several industrial products and applications over the last decade. Natural fibers as the reinforcing entity are pitted against their synthetic variants primarily because of the superior aspects like biodegradability and excellent strength-to-weight ratio. This article presents the review on various nonconventional natural fibers such as tamarind seed and shell, Luffa cylindrica, groundnut shell, coconut coir, papaya bast, okra, and Ashoka tree seed. The flow of the chapter includes the introduction, extraction methodologies, and fabrication, and investigations of mechanical properties, applications, and sustainability are dealt in detail for nontraditional natural fibers. The okra fibers possess greater tensile strength of up to 262.8 MPa in comparison with other fibers, while the Ashoka tree seed fibers are known to possess a maximum flexural strength of up to 125 MPa. Further, these fibers are used as reinforcements in potential applications in interiors and automobile and aircraft panels and wood-based particle board composites owing to the increase in tensile and flexural strengths of composites.

“…Many countries have already started utilizing natural ller-based composites in various applications, such as rail and decking products, car components, architectural moldings, and more. [52][53][54] Inorganic llers include various materials like zinc oxide, alumina, calcium carbonate, and silica, while organic llers consist of particulates derived from plants and animals. The quantity of ller added to the polymer matrix depends on the type of ller and matrix used, usually varying between 4% and 5% by weight.…”

“…The sustainability and strength characteristics of the composites are enhanced by the inclusion of fillers in the matrix and are ascertained from the findings of the several other researchers [17][18][19][20][21]. The strength and toughness of the polymer composites are enhanced by strong bonding between the matrix and the reinforcements, and also the molecular adhesion between the resin and fibers is enhanced by the filler materials that inoculate and create a stronger bond, thereby inhibiting the water uptake by the composites [22][23][24][25][26][27][28]. This serves as the major reason for using the mango seed shell as reinforcements in the matrix to improve the mechanical characteristics and reduce the moisture absorption by the composites.…”

The present work deals with the characterization of mango seed shell fiber reinforced epoxy composites by using hand layup method by varying the volume composition of the mango seed shell from 0 vol. % to 60 vol. % (M-0 to M-60). The physical density test, tensile test, flexural test, and water absorption test were conducted as per the American Society for Testing and Materials (ASTM) standards. Results revealed that the tensile strength of M-20 (20 vol. %) is 43% more than a neat epoxy, while the flexural strength of M-50 (50 vol. %) is greater than 10.85% more than a neat epoxy. The water absorption test was conducted by immersing the samples in distilled water at room temperature, and the weight of the specimens was measured and recorded at every 24-hour time interval. For all composite samples, saturation in water absorption and thickness swelling were observed after 432 hours of water immersion. The moisture absorption increases with the inclusion of reinforcements as compared to the neat epoxy samples. However, for the M-50 composite, the water absorption decreases due to the uniform mixing and stronger bonding between the matrix and the reinforcements. The scanning electron microscope (SEM) images of the composite specimens also depicted the particulate fiber distribution and the presence of micro-voids in the epoxy matrix.
