## 1 Introduction
The effects of intralayer fiber arrangement and internal pressure on mechanical response, damage propagation, and material cost-effectiveness were analyzed. It was found that yarn splitting of brittle carbon fiber and ductile glass fiber can induce in-yarn unsticking and delamination damage to prevent each other, and it easily produces out-of-plane displacement and shear stress under impact load. [PERSON] et al. [29] found that the fracture energy and delamination degree of the center carbon fiber layer could be controlled by adjusting the structural parameters to design the pseudo-ductility of carbon/glass (C/G) hybrid laminates and obtain the higher pseudo-yield stress. The highlights revealed the pseudo-ductility behavior of carbon/glass hybrid composites. The pseudo-ductility of carbon/glass hybrid composites is controllable. The pseudo-ductility strain increases with the increase in C/G ratio. The smaller hybrid fiber alternating unit avoids the aggregation of pure reinforced fiber material under the impactor, which is conducive to the hybrid impact toughening effect. The aluminum honeycomb panel plays an increasingly important role in modern industry due to its unique structure and performance, especially in the pursuit of lightweight and environmental protection. However, research on the mechanical properties of aluminum honeycomb sandwich panels remains limited both domestically and internationally. [PERSON] et al. [30] developed a finite element model based on higher-order shear deformation theory to investigate the free vibration and low-velocity impact transient response of doubly curved shallow sandwich shells integrated with laminated three-phase polymer/GNP/fiber face sheets and an auxetic honeycomb core resting on elastic foundations, unveiling the coupling mechanisms between material parameters and impact loads on the structure's dynamic behavior. [PERSON] et al. [31] systematically investigated pre-implanted core damage effects on aluminum honeycomb-reinforced composite sandwich structures through integrated experimental and numerical approaches. Quasi-static flexural/compression testing protocols quantified core damage-induced degradation in shear modulus (G) and [PERSON]'s modulus (E). Mechanical characterization reveals that the carbon/glass hybrid ratio directly modulates bending-impact performance synergies, necessitating further exploration of hybrid configuration effects on multifunctional carbon-glass honeycomb sandwich panels. In this paper, the mechanical behavior of aluminum honeycomb panels was studied deeply on the basis of the previous study. Based on the VARI molding process, sandwich structural composite faces were prepared by carbon plain weave fiber as the surface layer, glass fiber plain weave fabric as the core layer, and epoxy resin as the matrix, and then the carbon/glass mixed sandwich composite was prepared by bonding it with AL honeycomb core. Four kinds of samples with different hybrid ratios [32] were prepared, the effects of different hybrid ratios on the bending and low-velocity impact properties were analyzed. This study includes damage analysis and mechanical behavior change analysis of composite materials, which can provide a reference for the application of composite materials in the battery box shell.
