“…The surface treated fiber addition results in a decrease in the stress intensity factor in the resin matrix, causing in an increase in fatigue strength. [28,29] The E 2 composite designation shows more fatigue life counts then composite designation E 1 because of the change in staking sequences which sustained to crack propagation due to the roselle fiber on the top. When the load is applied, it transferred uniformly across the matrix due to superior bonding and the suppression of micro-crack formation represented in Figure 9A.…”

In this present study, a high‐performance structural epoxy biocomposite has been prepared and characterized for its mechanical, wear, and fatigue behavior. The main aim of this research was to determine the effect of fiber stacking order and the biosilica addition in the epoxy hybrid composite when it is subjected to external loading. The research also focused on how the surface treatment process on fiber and particle affects the mechanical, wear, and fatigue behavior of composite. The biosilica particles were synthesized from black rice husks and then surface treated with 3‐aminopropyltriethoxysilane. Similarly, a base treatment was applied to fiber mats and the composite laminates for this investigation were fabricated by hand layup process. It is noted that the composite designations E12 and E22 exhibited an improved tensile strength of 58, 62% and flexural strength of 45, 51% for 1.0 vol% biosilica in both staking sequence models. Similarly, in inter‐laminar shear strength the composites E2, E21 and E22 outperformed than E1, E11, and E12. In terms of Izod impact toughness and hardness, composite designation E22 provides maximum increment of about 94% and 5%. The wear resistance of composite E22 exhibited lower wear loss and COF. The highest fatigue life count of 41,782 was observed for the composite designation E22 in tension‐tension fatigue mode. Overall the stacking order R/A/G/A/R gives better results than others. These load bearing properties enhanced hybrid composites might be employed in structural, industrial, automotive, home appliance, defense, and lightweight industrial applications.

“…Composite materials play an important role in different industries due to their unique mechanical, physical, and morphological properties. [1][2][3][4] Fiber-reinforced composite materials provide high strength-to-weight and stiffness-to-weight ratios, high toughness, good fatigue properties, and corrosion resistance. [5,6] They can also be used as load-bearing parts, for instance as DOI: 10.1002/mame.202300077 orthopedic implants, where wear resistance and load-carrying capacity are important design parameters.…”

Bamboo fiber is one of the strongest natural fibers with high strength‐to‐weight and stiffness‐to‐weight ratios and can be used economically for manufacturing fiber‐reinforced composites. In this paper, bamboo fabric‐reinforced epoxy composite is manufactured and its tribological properties for load‐bearing applications are investigated. Sliding wear tests are conducted using a linear reciprocating tribometer and the effect of dry and lubricated contact conditions, applied load, sliding speed, temperature, and woven fabric direction on the coefficient of friction and wear rate are investigated. A scanning electron microscope is used to define the wear mechanisms at room and elevated temperatures. It is observed that the fabric orientation influences the mechanical and tribological performances of the composite material. Wear rate increases at higher loads and working temperatures; however, the effect of sliding speed is not remarkable, especially under lubricated contact conditions. The results present in this paper can be used for designing bamboo‐reinforced epoxy composites for load‐bearing applications, under different working conditions.

In this research, the epoxy resin was reinforced by (16 layers) of E-glass fiber woven mat (0^°/90^°) with 50% weight fraction and total thickness (3mm). Using 16 layers was due to the absence of any previous study that used this number of layers at this thickness. It is considered a modern study of this style because of the rapid development in modern engineering industries that required lightweight composite materials with high strength and small thickness, which are used in the aerospace industry aviation and other precision engineering industries. The composite material was cut into angles (0^°,5^°,15^°,30^°,45^°) by using CNC water jet culling machine. The tensile test was used to determine the strength of a material ratio to the fiber's direction and by using Vickers hardness to determine the hardness of composite and pure epoxy. The result of pure epoxy (matrix) has the lowest value in tensile strength (σ_UTS), Yong's modulus (E), 0.2% proof yield stress (σ_(0.2%)), modulus of toughness and toughness when compared with a composite material with adding 16 layers of "E-glass fibers". The direction of the fibers with (5^°) of composite has the highest strength, Young's modulus, and 0.2% proof yield stress when compared with (0^°,15^°,30^°,45^°) and pure epoxy. The improvement strength (10.8, 11.8, 9.8, 8.5, 8.3 times) at (0^°,5^°,15^°,30^°,45^°) respectively when compared with pure epoxy. The hardness of composite material improved (220%) relative to pure epoxy. The results show that the best improvement of composite material with fiber's angle (5^°) has the highest results compared with pure epoxy.
