“…The behavior of composite panels based on glass fiber woven fabrics and a bi-component epoxy resin under ballistic impacts was evaluated using a finite-element model at the meso scale [20] while considering parameters such as projectile material, size, and speed [44]. The development of a comprehensive framework for the design of composite structures at different levels requires accurate mathematical and computational models that can simulate the dynamic impact on composite panels [45]. Numerical studies have been conducted to investigate the damage effects on composite panel high-velocity impacts, considering different composite laminates and stacking sequences [46,47].…”

Body armor is critical to mitigating penetrating injuries and saving soldiers' lives. However, ballistic impacts to body armor can cause back deformation (BFD), posing a serious threat of fatal injury on the battlefield. The study performs finite element modeling to evaluate the protection of body armor panels. The numerical simulations consider various parameters, including impact velocities, and angles of projectile impact, which are used to estimate the residual velocity and damage patterns of the composite laminate. The simulations are carried out using the LS-DYNA code based on finite element analysis. The main results of the research reveal crucial insights into the ballistic behavior of composite materials with sisal and glass fibers. The study identifies specific responses, damage development patterns, and comparative analyses between sisal and fiberglass composites. The results have practical implications for the development of advanced materials to improve ballistic protection.

“…In real service environments, the thermal structural components of aerospace vehicles not only have to endure the erosion of high-temperature oxidation airflow, but also have to face the striking of birds or space trashes. 24 Due to the inherent brittleness, HfC coating cannot meet the service requirements of thermal structural components of aerospace vehicles solely relying on its own thermal protection ability. Aiming at this issue, some scholars proposed that introducing nanowires as reinforcements into ceramic to enhance toughness.…”

To inhibit the negative influence of impact on ablation performance of HfC coating reinforced by SiC nanowires (SiCnws/HfC coatings), BN interphases were fabricated and introduced into SiCnws/HfC coatings by chemical vapor deposition. The effect on BN interphase thickness upon SiCnws@BN/HfC coatings performance under impact‐ablation environment was investigated. The interphase thickness was adjusted by changing the deposition time of BN. Impact and ablation tests were carried out by drop hammer and oxyacetylene ablation devices. Among the prepared coatings, the one with 150±20 nm thickness interphase possessed a good performance under impact test, of which the crack propagation path exhibited a significant deflection. After ablation, the coating could still maintain intact surface, because the interphase thickness of 150±20 nm was appropriate to ensure the toughness of the coating and to avoid the porous structure formation.This article is protected by copyright.

“…Composite parts have excellent mechanical properties and low density and have been widely used in aerospace, automotive, and other fields. [1][2][3][4] The manufacture of composite parts generally requires molds to ensure the shape. Thermosetting continuous fiber-reinforced composites exhibit irreversible deformation during the curing process.…”

With the high precision requirements and the trend of large-scale composite parts, the development of composite molds is imminent. The short carbon fiber (SCF) composite mold is mainly prepared by the technological process flow of composite sheet injection, the bonding of composite plates, and machining. However, the current process optimization method has not matured adequately, and there are still many shortcomings, for example, low precision and high cost. In this paper, the optimization method of SCF/polyetherimide (PEI) composite molds is proposed. Many experiments have been conducted, and the results show that the coefficient of thermal expansion of composite samples can be effectively reduced and the mechanical properties can be improved by optimizing the SCF weight ratio and carbon fiber length. The bonding strength of composite joints in a high-temperature environment can be improved by optimizing the bonding process parameters and modification by carbon nanotubes. Based on the above optimization method, the SCF/PEI composite mold is prepared, and the C-shaped beam composite part is fabricated by using this mold. Compared with the part made by aluminum mold, the shape accuracy of the C-shaped beam composite part is proven high through digital measurement technology.
