Study on the Blast Resistance Characteristics of Polyurethane Foam-liquid Structures
This study investigates the blast resistance characteristics of polyurethane foam and liquid structures. Four typical protective configurations were designed: filled polyurethane foamball
annular polyurethane foam
annular polyurethane foam-liquid cover
and filled polyurethane foam ball-liquid. Experimentsand numerical simulations were conducted to analyze the performance of these structures in terms of shock wave peakpressure and flame protection. The results indicate that the filled polyurethane foamball-liquidprotectiveconfiguration exhibits superior protective efficiency per unit volume and mass
with a 77.7% reduction in shock wavepeakpressure compared to air blast. Flames were completely extinguishedat0.6 ms
demonstrating promising application prospects for these protective structures.
