“…The AA/epoxy composites exhibit better flexural properties, compared to rest of the composites, which can be explained by the perfect wetting of DPF, better dispersion, and good interfacial bonding between the filler and the epoxy matrix, which led to the formation of fewer voids and less fiber breakage. Other research works suggested that composites with lower lignin content possess better flexural properties, owing to better adherence between the fibers and the polymer matrix [54], thus providing an effective stress transfer between the reinforcement fibers and the matrix [55]. This is also in agreement with the findings of another study, which concluded that composites with lower lignin content exhibit better flexural strength [19].…”

The present study deals with the fabrication of epoxy composites reinforced with 50 wt% of date palm leaf sheath (G), palm tree trunk (L), fruit bunch stalk (AA), and leaf stalk (A) as filler by the hand lay-up technique. The developed composites were characterized and compared in terms of mechanical, physical and morphological properties. Mechanical tests revealed that the addition of AA improves tensile (20.60–40.12 MPa), impact strength (45.71–99.45 J/m), flexural strength (32.11–110.16 MPa) and density (1.13–1.90 g/cm3). The water absorption and thickness swelling values observed in this study were higher for AA/epoxy composite, revealing its higher cellulosic content, compared to the other composite materials. The examination of fiber pull-out, matrix cracks, and fiber dislocations in the microstructure and fractured surface morphology of the developed materials confirmed the trends for mechanical properties. Overall, from results analysis it can be concluded that reinforcing epoxy matrix with AA filler effectively improves the properties of the developed composite materials. Thus, date palm fruit bunch stalk filler might be considered as a sustainable and green promising reinforcing material similarly to other natural fibers and can be used for diverse commercial, structural, and nonstructural applications requiring high mechanical resistance.

“…Previously, cattail plants have been investigated for composite applications using whole cattail leaves (Stanescu and Bolcu 2019 ; Bazwa et al 2015 ), decorticated cattail leaves (Wuzella et al 2011 ; Mbeche et al 2020 ), milled cattail leaf mesh (Kongkaew et al 2018 ), and individual fiber without conversion into non-woven mats (Sana et al 2015 ). The extraction of textile-grade fiber from the cattail leaves has been demonstrated by Rahman et al ( 2021 ).…”

Vacuum-assisted resin transfer molding (VARTM), used in manufacturing medium to large-sized composites for transportation industries, requires non-woven mats. While non-woven glass mats used in these applications are optimized for resin impregnation and properties, such optimized mats for natural fibers are not available. In the current research, cattail fibers were extracted from plants (18–30% yield) using alkali retting and non-woven cattail fiber mat was manufactured. The extracted fibers exhibited a normal distribution in diameter (davg. = 32.1 µm); the modulus and strength varied inversely with diameter, and their average values were 19.1 GPa and 172.3 MPa, respectively. The cattail fiber composites were manufactured using non-woven mats, Stypol polyester resin, VARTM pressure (101 kPa) and compression molding pressures (260 and 560 kPa) and tested. Out-of-plane permeability changed with the fiber volume fraction (Vf) of the mats, which was influenced by areal density, thickness, and fiber packing in the mat. The cattail fibers reinforced the Stypol resin significantly. The modulus and the strength increased with consolidation pressures due to the increase in Vf, with maximum values of 7.4 GPa and 48 MPa, respectively, demonstrating the utility of cattail fibers from waste biomass as reinforcements.

“…This is due to the accurate composite manufacturing procedure, both natural fiber and epoxy matrix were well‐dispersed and strong interfacial‐bonded together, which decreases void formation and fiber breaking. Based on Sana et al, [ 56 ] due to greater adhesion between natural fibers and the epoxy polymer matrix, composites with decreased lignin concentration have superior flexural properties. Previous studies had discovered that the flexural properties of the epoxy reinforced composites is influenced by the fiber and the matrix properties, the level of homogeneity of the composites as well as the interfacial interaction among themselves.…”

The objective of this study is to evaluate the tensile and flexural properties of epoxy composites reinforced with sugar palm (Arenga pinnata) fiber (SPF) harvested from various geographical locations, in Malaysia; Kuala Jempol, Negeri Sembilan (SPFN9); Benta, Pahang (SPFP); and Tawau, Sabah (SPFS), and from Java, Indonesia (SPFJ). Due to its optimal chemical composition, which includes a higher proportion of cellulose (44.53%), hemicellulose (10.01%) and lignin (41.97%), SPFN9/epoxy composites have the best tensile and flexural strength, according to this study, with 27.09 MPa and 54.44 MPa, respectively. The composites demonstrate slight decreases in the tensile strength (about 27-36%) and flexural strength (about 26%-42%) compared to the neat one. This is associated with the insufficient filling of the polymer amount. The hydrophilic characteristic of SPF makes it tough to bind to hydrophobic epoxy, creating a difficulty with interfacial adhesion between the filler and matrix. Thus, the SPF needed to be treated prior to the fabrication of composites to improve its mechanical properties for structural and automotive applications.
