Abstract This study investigates the effects of various fibers and their combinations on mechanical properties fiber-reinforced cementitious composites (FRCC). Sixteen distinct mix designs were prepared, each incorporating different types proportions fibers, Polyvinyl Alcohol (PVA), Polypropylene (PP), Basalt, Banana while maintaining a consistent cement-to-sand ratio 25% to 75%. The objective was evaluate how these influence compressive, flexural, tensile strengths FRCC. results revealed significant variations in based fiber type content. Mixes containing PVA Basalt demonstrated superior compressive strength, flexural strength compared those with other fibers. Notably, hybrid combinations, such as or PP, showed enhanced performance, indicating synergistic benefits combining types. In contrast, alone less effective improving but contributed positively when combined synthetic highlights potential hybridization optimizing performance composites. strategic use both individually combination, provides promising approach for developing high-strength, durable FRCC suitable diverse construction applications. These findings offer valuable insights future research development advanced composite materials tailored properties.

Abstract When the variety of synthetic polymers came up in 20th century, they expectedly replaced many fiber materials which were made so far from biopolymers since ancient times (e.g., for textiles, medical products, etc.). Meanwhile, to some extent, there is a strong revival various fibers regarding their utilization applications, based on interesting structures, availability, sustainability, costs, and other factors. Regarding bioeconomy has thus been an intensive market dynamic biopolymers. Therefore, especially have recently described that are different as, e.g., polysaccharides biopolyesters. For this, enhanced polymer structure modification sophisticated processing methods applied. Instead complete comprehensive overview (which would be beyond scope this Perspective format), aim article elucidate selected recent advantages field focus special features these examples.

Abstract This study investigates the impact of chemical treatments on physico–chemo–mechanical properties mechanically extracted yucca fibers and mechanical performance epoxy‐based bio‐composites. Initially, are treated with sulfuric acid (H 2 SO 4 at 1% 4%, during 30 min) sodium hydroxide (NaOH 3% 8%, 120 min), aiming to enhance their properties. Scanning electron microscope (SEM) analysis reveals improved surface quality reduced diameters, while fourier transform infrared spectroscopy (FTIR) confirms functional groups. Yucca‐treated exhibit significant tensile strength improvements, increases 101.22% (518 MPa) for NaOH 93.33% (497 those acid, compared untreated (257 MPa). Subsequently, bio‐composites elaborated via mold casting technique using these demonstrate enhanced performance. Tensile by 25% (29.6 45% (34.4 composites reinforced respectively, fiber (23.6 Similarly, compressive improves 23.35% (79.5 9.85% (89.3 MPa), bending reaches 41.03 MPa (4.3%) 45.27 (15.1%) respectively.

Abstract The utilization of biofiber in recent years has significantly increased due to its advantages like being environmentally friendly, availability, and low costs. This paper investigates the physicochemical, mechanical, morphological properties yucca fiber extracted by three methods such as water‐retting, traditional, chemical methods. These analyses are designed evaluate extraction methodology hypothesis influence harvesting location growth conditions fiber. Various technologies used, SEM, FTIR, XRD, tensile tests. water retting is strongest mechanical analysis with a strength 690.48 MPa, followed traditional method 685.48 also 673.06, 657.94, 373.68 MPa for using 3%, 5%, 10%NaOH respectively. obtained higher composition 80.25% cellulose, 10.45% lignin, 13.75% hemicellulose. characteristics examined Scanning Electron Microscopy. crystallinity index ranged from 61.75% 70.77%, crystallite size 1.73 2.04 nm calculated XRD analysis. All these results confirm that can be good sustainable choice composite reinforcement.
