A new type of reinforced concrete slab wrapped with glass fibre reinforced polymer (GFRP) is proposed, which is composed of GFRP profile slab wrapped with reinforced concrete slab. In order to master the anti-explosion performance of the new composite slab structure under the action of explosion, the dynamic response results of the new wrapped glass fibre reinforced concrete slab structure and the ordinary concrete slab structure under the action of explosion are analyzed and compared by using ANSYS/LS DYNA and fluid structure coupling algorithm. The results show that the new wrapped glass fibre reinforced concrete slab structure, which through the sand bonding treatment of GFRP ribbed slab and inner surface, GFRP slab is closely combined with concrete, giving full play to the superposition effect of GFRP and concrete on explosion impact resistance, which has better explosion impact resistance than ordinary reinforced concrete slab structure, and provides important support for the application of GFRP reinforced concrete composite structure.
