“…Finite element analysis study on chopped carbon prepreg with an aluminum sheet could predict the tensile behavior of the composite compared to experimental results using CZM and the Hashin damage criterion. 29,30 However, a two-dimensional finite element model was used, which simplifies the elastic equations to two-dimensional. Moreover, it is essential to observe the deformation of the materials under loading to understand the deformation trends that lead to the pseudo-ductile behavior.…”

Thin-ply hybrid laminates of glass and carbon fibers have been widely adopted in engineering pseudo-ductility. In this study, a Finite Element model is proposed using Abaqus to predict pseudo-ductility in thin-ply laminates consisting of three materials. These materials comprise continuous carbon (CC) and continuous glass sandwiching partial discontinuous carbon (DC). The model adopts the Hashin criterion for damage initiation in the fibers and the mixed-mode Benzeggagh-Kenane criterion on cohesive surfaces for delamination initiation and propagation. Numerically predicted stress–strain results are verified with experimental results under tensile loading. Results show pseudo-ductility increases with the increase in DC layers, and pseudo-yield strength and strain increase with the increase in CC layers. 3D-Digital Image Correlation results indicate delamination growth on pseudo-ductile laminates, and the calculated Poisson’s ratios show pseudo-ductility occurs below 0.27. Moreover, Poisson’s ratio decreases with an increase in pseudo-ductility.

“…For the past few years, the development of carbon fiber reinforced aluminum matrix composites has mainly focused on short fibers, particles, and continuous carbon fiber bundles [7][8][9][10][11]. The addition of short carbon fibers and particles as reinforcements has the advantage of being easy to disperse, which can ensure that the properties of the composite material are uniform in all directions and that it has more excellent maneuverability during the preparation process [12][13][14][15]. However, due to the small fiber size, it is inevitable to introduce a large number of fiber fracture interface between the matrix in the composites, which increases the material's sensitivity to deformation, reduces the reinforcement efficiency of carbon fibers, causes stress concentration due to segregation and sharpening, and, finally, greatly affects the properties of composite materials.…”

Carbon fiber is mainly distributed in the shape of short fibers and continuous fiber bundles as the reinforcing phase in metal matrix composites, and it is seldom studied as braided rope shaped to reinforce the matrix. For this paper, the pretreatment and the surface metallization of the carbon fiber braided rope were studied. Besides, the casting experiments of aluminum-based carbon fiber braided rope composites were performed without external pressure. XPS analysis shows that the surface of the carbon fiber braided rope treated with ultrasonic degumming contains many hydrophilic oxygen-containing functional groups C-OH, C=O, COOH, etc., which can effectively improve the wettability between the carbon fiber braided rope and the aluminum matrix. SEM, EDS, and XRD were used to analyze the micromorphology and structure of the copper plating on the surface of carbon fiber braided ropes obtained from different pH plating solutions. When pH is 12, a continuous, uniform, and dense layer was formed on the surface of carbon fiber braided ropes. In addition, copper coating can effectively inhibit the formation of Al4C3 brittle phase. Finally, the mechanical properties results indicated that the tensile strength of the carbon fiber bundle and carbon fiber rope reinforced composite materials were 69 MPa and 83 MPa, respectively, indicating that the reinforcing effect of the carbon fiber rope is better than that of the carbon fiber bundle.

In this article, the open‐hole tensile behaviour of carbon fibre reinforced aluminium laminates (CARALL) were investigated experimentally and numerically. Two specimens with different fibre orientations ([0°/90°/0°] and [45°/0°/−45°]), consisting of T700 carbon fibre/epoxy prepreg and 2024‐T3 aluminium with a 3/2 configuration, were manufactured by the autoclave process. Damage initiation and progression were considered in modelling the CFRP layers and interface bonding layers. Isotropic hardening behaviour was defined for aluminium layers. A major contribution of this study was to reveal the failure mechanisms and failure sequences of notched CARALL with different fibre orientations by numerical method. Damage evolution processes of the two specimens were compared. Effects of hole sizes and laminate configurations (stacking sequences & stacking structures) on both the specimens were further evaluated based on simulation. Point stress failure criterion and Wu's modified point stress failure criterion were applied in comparison with the numerical method as well. POLYM.
