“…Hussein Dalfi et al 16 designed a new fiber hybridization process using an in-layer toughening mechanism to enhance the impact resistance of 2D braided composites. By embedding elastic shape memory alloys in the fiber reinforced composite structure, Luv Verma et al [17][18][19][20] improved the in-plane transverse mechanical properties of the structure and increased the interlayer bonding force, thus improving the impact resistance of the structure.…”

In this work, the failure mode and ballistic protection capability of the carbon fiber aluminum alloy laminated target plate under the impact of high‐speed projectile body were studied by ballistic impact test. The effects of the lamination sequence and warhead shape difference on the impact resistance of the laminated aluminum alloy and carbon fiber laminates were analyzed. Two kinds of projectile bodies, flat and oval head, were used to carry out multiple high‐speed impact experiments on four groups of targets with different stacking sequences. By analyzing the result, it is found that the lamination sequence of the target plate has a significant effect on the anti‐impact performance only when the flat head projectile impacts, while the ovoid projectile has almost no effect. In the fiber‐metal composite configuration, the aluminum plate placed in front of the carbon fiber plate showed the best resistance to flat head bullet impact, the ballistic limit speed reached 135 m/s, and the overall impact resistance improved by up to 26% compared with other configurations. Unlike the shear failure caused by flat head projectile, ovoid projectile impact can cause serious tensile and tear damage. Based on the experimental results, it is clear that the laminated structure has better penetration resistance against the flat head projectile, and the placement of aluminum plate on the impact surface can change the failure mode of carbon fiber laminates and improve the energy absorption level of composite plates.Highlights Unlike traditional fiber‐metal laminates, the target plate used in this experiment does not use adhesive, which makes the deformation of the two materials will not affect each other, which is conducive to the study of its own impact resistance. The mechanical behavior and damage failure mode of the target plate under high speed impact load were studied. The impact of ovoid projectile changes the damage failure mode of the target plate. For the configuration of fiber‐metal laminates, the ballistic limit value is as low as 100 m/s, and the energy absorption value fluctuates in the range of 145–190 J with the change of impact velocity. Compared with ovoid projectile, laminated material has stronger impact resistance to flat head projectile. The metal plate arranged on the impact surface can change the damage mode from shear failure to tensile failure, thus greatly improving the ballistic limit and impact resistance, overall impact resistance can be improved by up to 26%.

“…Plain woven composites are significantly different from traditional UD composites in terms of periodic symmetry and cross ply. Therefore, scholars studied the influence of a single repair parameter on the mechanical properties of the repaired woven composite structure through a large number of experiments from simple to in‐depth 16–23 . In the research of Andrew et al, 16 they used experimental methods to study the impact resistance and post impact tensile properties of composites repaired with hybrid patches composed of glass fiber woven materials and aluminum alloy materials.…”

Patch-repaired plain woven composite structures were exposed to internal damage caused by impact during service, which reduced mechanical properties. A multi-scale modeling strategy was proposed to study the impact resistance characteristics of patch-repaired plain woven carbon-fiber-reinforcedpolymer (CFRP) laminates. The micro representative volume element (RVE) was extracted from the yarn; a local homogenization method was used to obtain the equivalent cross-ply laminate (ECPL) cells corresponding to the mesoscale RVE. The finite element model (FEM) of patch-repaired plain woven laminate was established by extending the ECPL cells. The FEM was checked by the low-velocity impact (LVI) tests, and the impact parameter errors were within 10%. Furthermore, impact resistance of repaired specimens under different impact conditions (e.g., the impact energy was 3 $ 20 J) was studied. Finally, patch parameters (patch thickness, patch size, off-axis angle) of the repaired specimen were optimized by multi-objective optimization based on the surrogate model and response surface method (RSM). After multiobjective function optimization, the optimal patch parameter configuration (the thickness of the patch was 0.87 mm, the diameter was 66 mm, and the off-axis angle was 44.2 ) reduced the absorbed energy value of the repaired specimen from 4.9089 to 4.1640 J, and the delamination area of the repaired specimen from 605 to 280 mm 2 . All the results provide a reference for patch repair of plain woven composites.damage evolution, multi-objective optimization, multi-scale modeling, patch repair, plain woven CFRP composite | INTRODUCTIONPlain woven carbon-fiber-reinforced-polymer (CFRP) composites have better interlaminar and in-plane strength due to their complex internal fabric structure, compared with unidirectional (UD) fiber composites. However, woven composite structures are vulnerable to internal damage caused by impact during service, which reduces mechanical properties. In order to reduce the maintenance cost, people often repair the damaged part of the structure to achieve the expected mechanical properties. Adhesive bonded repair 1,2 has been widely used in the repair of composite materials due to its ease of operation and less additional weight. The repair parameters of adhesive
