Natural fiber‐reinforced composites exhibit excellent mechanical properties. However, achieving a balance between excellent mechanical properties and optimal acoustic performance remains a challenge. In this study, four composite laminates with different stacking orders were fabricated using polyester fiber mats (WFs) and palm sheaths (WPs) through a hot‐press process. Moreover, the effects of different stacking orders on the mechanical and acoustic properties of the composite were investigated. The results revealed that the incorporation of polyester fiber felts and the modification of the layup sequence of WP and polyester fiber felts significantly improved the mechanical and acoustic properties of the composites. Scanning electron microscopy images revealed a strong bonding between palm fibers and polyester fibers at the epoxy resin interface. Compared with pure palm fiber composites, the alternately stacked palm fibers and polyester fibers (WP/WP/WF/WP/WF) exhibited the highest mechanical properties, with a significant enhancement of 142.67% and 16.90% in flexural and tensile strengths, respectively. Additionally, the peak absorption coefficient of polyester fiber felts, positioned in the surface layer of the composite material, within the 2580–3400 Hz frequency band significantly increased from 0.07 to 0.44. Therefore, this study indicates that modifying the stacking order improves the mechanical and acoustic properties of the composites, making them suitable for use in acoustic engineering materials for buildings and decorative panels for furniture, including perforated panels and acoustic screens.Highlights The fabric‐like textured structure significantly enhanced the overall performance of the composites. The stacking order significantly influenced the overall properties of the composite. Alternately stacked polyester fiber felts and palm fibers exhibited excellent mechanical performance. The polyester fiber felts positioned on the surface layer of the composites exhibited superior mechanical performance. A laminate with “green” attributes and good acoustic properties was fabricated.

“…This is carried out in accordance with the numerical representation of the delamination and the implementation of the Paris law. Interface elements with an incorporated cohesive law are widely used in damage mechanics simulations of delamination onset and propagation under quasi-static and impact stress conditions [5,6]. As a result of the positive findings gained for these issues, a select group of writers has extended the cohesive formulation in order to mimic the growth of fatigue cracks.…”

In this investigation, a kenaf/PLA composite specimen was subjected to the fatigue load, and the results were analyzed numerically. Some of the most significant fatigue tool aspects that were looked into were life expectancy, damage, alternative stress, and biaxiality indication. The static structural tool was utilized in order to predict the numerical analysis, and the calculations were performed with the GoodMan theory of fatigue. The loading was completely reversed so that it was equal to 30 kN. When it was discovered that the system could continue to function even after 1e6 cycles had been completed. After applying the alternative load of 30 kN, the biaxiality indication was found to be 0.425, with a minimum value of 0.9. It has been determined how much damage has occurred. The minimum amount of cycles necessary to reach the maximum damage potential is 1000, while the maximum amount of cycles necessary to reach the maximum damage potential is 1.7662·106. It has been established that there is another stress that is comparable to this one. Based on the findings of the investigation, it was determined that the fillet regions of the specimen were subjected to a maximum alternative stress of 716.4 MPa. The alternative stress cannot drop below 31.276 MPa under any circumstances. It has been determined that 106cycles have been spent living in total by the calculation. It has been found out that there is not going to be any damage regardless of the number of cycles that pass due to the fact that that number is 1. It was found that the alternative stress could reach a maximum value of 716.4 MPa, so that was the value that was used for the alternative stress

This study examined the mechanical performance of two polyester resins (isophthalic and orthophthalic) used to create e-glass-based laminate composites for the marine industry. The current study performed a static analysis of laminate composites using compressive, impact and hardness tests. Single edge-notched beam (SENB) fracture tests under mode I (i.e. opening mode) were performed on e-glass reinforced orthophthalic polyester laminate composites (S1) and e-glass reinforced isophthalic polyester laminate composites (S2) at cryogenic temperature (−10°C), ambient temperature (25°C) and high temperature (100°C). The interaction between fibres and matrix material was studied using Fourier transform infrared (FTIR) spectroscopy. A scanning electron microscope (SEM) was used to examine the substructure of fractured surface. A water absorption test was also performed on the fabricated samples. FTIR study revealed NH stretching, CH bend, CN stretching, C-O-C and CH-stretching. e-Glass isophthalic polyester composites had higher compressive strength, impact strength, hardness, fracture toughness and fracture energy than orthophthalic polyester laminate composites. The decrease in temperature increased the fracture properties. In both types of laminate composites, as the temperature increased, the fracture toughness and fracture energy decreased. The diffusion and permeability coefficients of isophthalic composites were greater than those of orthophthalic-based composites. The crushed fibre, fibre pull-out, riverline, matrix-fibre delamination and debonding are all evident in the fractured surface SEM micrograph.
