“…The numerical simulated damage patterns of 2DTBC are similar with those reported in [6,7], which also used a highly efficient homogenized model to simulate the impact performance of a two-dimensional triaxial braided composite casing. While the previous studies [6] were concerned with the effect of projectile shape, this study analyzed more extensively the damage morphology of composites with different architecture.…”

“…Overall, it is found that when the angles α and β are larger than 20°, the damage tolerance for the composite panels is substantially unchanged against the change of projectile deflection angle α , while the impact resistance changes a lot against the change of velocity deflection angle β . Most of the existing studies deal with the effect of projectile shapes and material properties on the damage behavior of composite plates [2,3,4,5,6,7,8,9]. This study provides additional understanding on the effect of architecture type and impact attitudes on the impact resistance of composite panels, which could be useful for the design of composite protective structures.…”

“…Vanderklok et al [5] investigated the ballistic impact resistance of glass/epoxy composites with a number of layers and identified that a 6-ply (3.9 ± 0.3 mm) panel presented 12% more efficiency in energy absorption than that of a 10-ply (6.19 ± 0.1 mm). Liu et al [6] studied the containment capability of a 2D triaxially braided composite casing using a spin tester and identified that fiber shear fracture is the main failure mode on the inner wall, while fiber tensile fracture and delamination failure are the main failure modes for the outer wall. Liu et al [7] conducted a short-beam shear test on aged unidirectional CFRP specimens to evaluate the degradation of interfacial properties and investigage the effect of hygrothermal aging on the ballistic limit of composites.…”

“…Tan et al [23] developed a macro-scale finite element model for impact failure simulation of triaxially braided composites, and numerically investigated the influence of braiding angles on the impact resistance and failure behavior of the composite panel. Similarly, Liu et al [24] built a macro-scale finite element model for a triaxially braided composite, efficiently simulated the fan-blade-out impact performance of a composite casing structure, and investigated the effect of impact velocity and structure thickness on the damage tolerance of the casing structure. Omar et al [25] illustrated the different failure behaviors between hollow-core fiber-reinforced polymer columns under dynamic impact conditions.…”

The impact resistance of fiber-reinforced polymer composites is a critical concern for structure design in aerospace applications. In this work, experiments were conducted to evaluate the impact performance of four types of composite panels, using a gas-gun test system. Computational efficient finite element models were developed to model the high-speed ballistic impact behavior of laminate and textile composites. The models were first validated by comparing the critical impact threshold and the failure patterns against experimental results. The damage progression and energy evolution behavior were combined to analyze the impact failure process of the composite panels. Numerical parametric studies were designed to investigate the sensitivity of impact resistance against impact attitude, including impact deflection angles and projectile deflection angles, which provide a comprehensive understanding of the damage tolerance of the composite panels. The numerical results elaborate the different impact resistances for laminate and textile composites and their different sensitivities to deflection angles.

Currently, modern CAE programs like ANSYS, LS-DYNA, ABAQUS, Simcenter 3D etc. are widely used to develop each engineering product. CAE reduces development costs and speeds up product launches. Computer modelling allows eliminating unsuccessful design options at early design stages and minimising or eliminating critical design changes at the prototype testing stage. Computer simulations are especially needed for the development of high-performance perfection designs like jet engines. The use of composites in the engines requires the availability of appropriate design tools to assess the mechanical behaviour of structural elements made of such materials under operational loads and in an emergency. Predictive modelling of the deformation and fracture of the composite fan blades and fan case subjected to dynamic loading cause considerable interest of engineers. As in the case of simulation of shock loading of metals, a model of a composite material must be verified. However, the problem is that the fibrous composite material itself is already a structure and can be modelled in various ways: without considering the layered structure (homogeneous approach) taking the mesostructure into account (at the ply-level or at the yarn-level) taking the microstructure into account (at the filament level). The requirements for the initial data, the number of parameters determined during the verification process, the complexity of creating geometric models will differ in each case. This paper briefly describes the main approaches to the numerical simulation of composite elements under highvelocity impact loading. The main advantages and disadvantages of these approaches are also considered. On the example of the meso-scale approach, the main parameters of the computational models that affect the results of calculations are shown. Based on the obtained data, the main recommendations were formulated on the validation of meso-scale models of composites.

The structural properties of braided composite laminates are significantly affected by the low‐velocity impact (LVI). In this paper, the impact resistance and damage tolerance of triaxial braid structure laminates at different positions were mainly studied. Three hybrid biaxial (B)/triaxial (T) braided composite structures of BBTT, BTTB, and TTBB were designed, and LVI test and post‐impact compression tests were carried out. The results show that the triaxial braided fabric with quasi‐isotropic on the impact side caused more significant matrix cracks along the axis yarn direction, and the matrix damage area and delamination area were larger. For triaxial braided ply with high curl levels, severe fiber fracture and relatively concentrated damage occurred first on the non‐impact side. Interestingly, triaxial braided fabrics exhibited better impact resistance in terms of mechanical response when distributed across the specimen surface. However, a global damage pattern appears at high energy levels, which seriously reduced the residual strength of the structure and showed the worst damage tolerance. The damage quantification analysis of cracks, dent depths, delamination and residual compressive strength caused by the LVI of hybrid shaft number braided laminates was carried out in this work, which provided a valuable reference for engineering failure analysis and rational structure optimization of composite laminates.
