High-performance ballistic fibers, such as aramid fiber and ultra-high-molecular-weight polyethylene (UHMWPE), are commonly used in anti-ballistic structures due to their low density, high tensile strength specific modulus. However, modulus the thickness direction insufficient shear limits application certain structure. In contrast, carbon reinforced epoxy resin matrix composites (CFRP) have characteristics of resistance. fibers rarely applied for protection purposes. A hybridization with...
The relationship between the mechanical and ballistic properties of armored ceramics was studied using a numerical method that combines finite element simulation machine learning. A dataset containing physical properties, performance ceramic built through with JH-2 model. learning employed to establish residual penetration depth ceramic' including its density, elastic modulus, Poisson's ratio, Hugoniot limit (HEL), dynamic compressive strength, quasi-static bending strength. Through...
Ceramic materials play an important role in the composite armor structures used to defend against armor-piercing projectiles. Previous studies have focused on understanding ceramics' energy absorption and ballistic properties under strong constraints. Specifically, this research studied of silicon carbide (SiC) ceramics weak support conditions. Ballistic tests were performed measure resistance SiC with different thicknesses 7.62 mm M2 (AP) projectiles The results then simulated analyzed...
In this study, the filling and solidification processes of squeeze-casting SiC3D/Al composites were analyzed by ProCAST simulation software (ver. 2018.0). A practical experiment was conducted to verify accuracy results. series orthogonal experiments on initial preheating temperature various components identify optimal parameters in order achieve better porosity stress concentration values. According results analyses, mold most important determining factor. Under a pouring 700 °C, 200 SiC...
Ceramic composite structures are important in developing lightweight protection applications. Designers primarily design for armor-piercing threats. However, it is difficult to avoid the threat of high explosives or improvised explosive devices on battlefield. In this work, three ceramic with different type and thickness panel were assessed by explosion test finite element modelling study their damage failure characteristics. The exhibit good wave weakening ability. does not change...
The effect of interlayer materials on the damage ceramics in SiC/Al compositestructure was analyzed through experiments and simulation. Using 0.25 mm thermoplasticpolyurethane (TPU) as a reference, 0.5 aramid fabric (AFRP) or carbon fiberreinforced epoxy matrix composite (CFRP) added to interlayer, respectively. Through theimpact tests, it discovered that ceramic damaged area TPU structure wassevere. With addition AFRP, layer reduced by 73%under same impact conditions. CFRP also ceramics....
The development of potent pseudocapacitive charge storage materials has emerged as an effective solution for closing the gap between high-energy density batteries and high-power long-lasting electrical double-layer capacitors. Sulfonyl compounds are ideal candidates owing to their rapid reversible redox reactions. However, structural instability low conductivity hinder practical application electrode materials. This work addresses these challenges using a fast clean laser process...
The ultra‐high molecular weight polyethylene (UHMWPE) fiber laminates were prepared by hot pressing at temperatures ranging from 120 to 140 °C and pressures of 15 25 MPa. Mechanical test results demonstrated that increasing the molding temperature improved interlaminar shear strength, in‐plane bending strength laminates. Additionally, tensile properties laminate influenced both positive effect increased bond negative reduced strength. mechanical showed improvements −50 but decreased 70 °C....
Abstract To resolve the dilemma between impact resistance and structural stiffness of fan containment casing modern civil aeroengines, a novel composite structure (CS) is proposed. It combines hard stiff ceramic which layered at side lightweight tough polymeric matrix composites (PMC) on back side. The new was tested under ballistic loadings quasi-static four-point bending. results indicate that improved, compared with PMC-only samples. Meanwhile, bending also substantially larger cost much...
