“…The demand for environmentally friendly materials has encouraged the development of research to replace synthetic glass and carbon fibers, which are the most used as reinforcements in polymer composites, with natural fibers [1,2]. The high demand for polymeric composites reinforced with glass fibers for manufacturing parts has generated a significant waste of materials in the manufacturing process [3].…”

“…Among the varieties of vegetal fibers that can be inserted into the polymeric composite, alternating the directions of the layers, is the Asian species Luffa cylindrica, popularly known as loofah. In Brazil, the loofah is widely cultivated in the North and Northeast regions, where it is used as bath sponges and to produce biodiesel, making of insulation boards, and wastewater treatment [1,7,[11][12][13]. The mature bushing presents a fibrous structure with excellent properties of resistance, stiffness, and energy absorption capacity, in addition to having a low cost, being light, abundant in nature, and having a morphology that favors good fiber-matrix adhesion [7,14,15].…”

The arrangement of layers of natural long fibers that compose a polymeric composite can result in a final material with greater mechanical strength, in addition to replacing synthetic glass and carbon fibers. This study proposed different configurations of layers of loofah fibers (Luffa cylindrica) to produce reinforced polymeric–polyester composites, determining their potential mechanical properties such as flexural strength and Rockwell hardness. The layers were arranged by varying parallel and perpendicularly the direction of the loofah fibers pieces. The reinforcement decreased the density of all composites, with the lowest value, 1.03 g cm−3, indicated by the configuration 90°/0°/90°. The composites in the configuration 0°/90°/0° presented the highest value among the reinforced compositions (10.8 MPa), in addition to the highest rigidity value during bending tests (774.8 MPa). In the Rockwell hardness tests, the treatment reinforced with fibers in the configuration 90°/90°/90° had the highest value among all experimental treatments with a value of 86.9 HHR. The configuration angle of the loofah layers has a significant impact on the mechanical performance of the composites and should be taken into account in their confection. Furthermore, composites reinforced with loofah fibers in different configurations have physical–mechanical properties that qualify them for non-structural applications in indoor environments.

This research delves into incorporating Calamus tenuis fibers as reinforcing material in polymer composites, conducting a thorough analysis of their viscoelastic, mechanical, and morphological attributes. Employing the hand layup method, Calamus tenuis fiber‐reinforced epoxy composites were crafted across a range of fiber loadings from 0 to 25 wt% with 5 wt% increments. Results highlight significant enhancements in mechanical attributes upon the incorporation of Calamus tenuis fibers into the matrix. Notably, the composite with 10 wt% Calamus tenuis fibers emerges as the top performer, showcasing unparalleled mechanical strength compared to neat epoxy. It achieves the highest tensile strength (21.08 ± 1.03 MPa) and tensile modulus (2.84 ± 0.09 GPa), along with the utmost flexural strength (63.31 ± 1.05 MPa) and flexural modulus (3.12 ± 0.16 GPa). Furthermore, it demonstrates remarkable impact strength (9.40 ± 0.40 J/cm2), emphasizing its resilience. Scanning electron microscopy (SEM) analysis confirms enhanced fiber‐matrix adhesion in the 10 wt% composite. Additionally, dynamic mechanical analysis (DMA) results reveal enhancements in storage and loss modulus, with the 10 wt% composites exhibiting the highest values. However, the damping factor decreases with the inclusion of Calamus tenuis fibers. Overall, a 10 wt% fiber loading is deemed ideal for enhancing the mechanical and dynamic properties of epoxy composites.Highlights Utilized Calamus tenuis fibers as reinforcing materials in epoxy composites. Investigated the mechanical, morphological, and viscoelastic properties. Calamus tenuis fibers boost epoxy composite mechanical traits significantly. SEM confirms improved fiber‐matrix adhesion in 10 wt% composite. DMA highlights elevated storage and loss modulus in 10 wt% composites.
