AI Technical Summary
Existing protective structures are heavy, have poor thermal insulation, and their material properties are prone to failure in high-temperature environments, making it difficult to achieve both lightweight and explosion-proof performance.
It adopts a multi-layer composite structure, including a blast-facing layer, a composite material sandwich layer, a heat insulation layer, an energy-absorbing layer, and a back blast layer. A filling cavity is formed by a metal skeleton and filled with the composite material sandwich layer, heat insulation layer, and energy-absorbing layer. Combined with high-strength alloys, lightweight foam materials, and aerogel insulation felt, it achieves lightweight and efficient energy absorption.
While ensuring explosion resistance, the weight is significantly reduced, the heat insulation effect is improved, the material performance is protected and the application scenarios are broadened, and excessive overall deformation and material failure are avoided.
