“…As it can be seen, by increasing the impact velocity, the efficiency of the laminate decreases in all configurations. This has also been observed by Wang et al [39] in Carbon/epoxy composites and by VanderKlok et al [40] in glass/epoxy systems and is attributed to existing a critical velocity, at velocities above which a localization is occurred. When the impact velocity varies from below to above critical velocity, the failure modes are switched from global deformations and tensile damages to local shear failures.…”

“…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.…”

“…Yang et al [4] investigated the high-speed impact failure mechanism and energy absorption feature of 3D braided composites with the assistance of a 3D digital image correlation (DIC) technique for strain-field measurement. 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.…”

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.

“…For the anisotropy of continuous fiber-reinforced composites, an experiment is the most effective way to investigate the mechanical properties of them [ 10 , 11 ]. Researchers have carried out high-velocity impact experiments and found that composites had high ballistic resistance [ 12 ]. What is more, composites exhibit different mechanical properties at different strain rates.…”

Investigation of the Ballistic Performance of GFRP Laminate under 150 m/s High-Velocity Impact: Simulation and Experiment

The ballistic resistance of GFRP laminates subjected to high-velocity impact was studied. Based on the damage situation of GFRP laminate observed from the single-stage gas gun testing, the three-dimensional (3D) model combining strain rate effect and Hashin failure criterion was established, and the result presented good agreement between the simulation and experiment. Three factors, including layer angle, stacking sequence and proportion of different layer angles, were taken into consideration in the models. An orthogonal test method was used for the analysis, which can reduce the number of simulations effectively without sacrificing the accuracy of the result. The result indicated a correlation between the ballistic resistance and layouts of GFRP laminates, on which the stacking sequence contributed stronger influence. What was more, the laminate with layer angles 0°/90° and ± 45° presented greater ballistic resistance than the other angle pairs, and adopting an equal proportion of different layer angles is helpful for GFRP laminates to resist impact as well.
