This study investigates the mechanical behavior and failure mechanisms of SFHCPs under low-velocity impact compression after (CAI) conditions. Symmetric foam-filled hat-stiffened composite panels (SFHCPs) are widely used in critical load-bearing structures such as vessels aircraft due to their high strength-to-weight ratio integrated stiffener design. However, material’s sensitivity impact, it is necessary conduct a systematic evaluation its application reliability. By integrating experimental testing numerical simulation, buckling modes characterized by symmetry envelope number were adopted key performance indicators. The integration an optical measurement method with iterative finite element model (FEM) updates significantly enhances accuracy computational efficiency. Experimental results indicate that for specimens impacted at mid-section residual compressive strength drops sharply from 106 kN 40.6 (a reduction 61.7%), mode changing symmetric four-wave pattern undamaged state localized region, leading brittle failure. FPP data improved FEM, highlighting influence optimizing impact-resistant structures.

Formaldehyde-based adhesives, commonly used in traditional plywood, pose significant health and environmental risks. In contrast, green geopolymers, which offer benefits, are limited plywood applications due to their inadequate toughness. This study introduces a geopolymer adhesive that incorporates unique "brick mortar" (BM) structure inspired by natural shells, using fly ash as the primary raw material metakaolin an active additive. The is enhanced gel formed through pretreatment alkali activation, serving inorganic "mortar" phase, while unreacted minerals act "brick" phase. Epoxy resin KH550 integrated organic organic-inorganic coupling phases, respectively. composition not only improves toughness but also facilitates formation of "gradient gradual changing" (GGC) at interface during hot pressing, significantly enhancing bonding performance. Experimental results reveal prepared this achieves wet shear strength 1.31 MPa, 385% improvement over exhibits superior flame retardancy approach offers novel efficient strategy for developing high-performance paving way advanced utilization industrial like ash.
