STUDY ON THE EFFECTIVENESS OF HOLE OPENING ON THE BLAST RESISTANCE OF A BASALT FIBER COMPOSITE DOOR
Fiber-reinforced composites (FRP) features lightweight, high strength, good corrosion resistance, and en-vironmentally friendly, which received wide attention in engineering. Traditional underground doors are mostly made of steel, whereas basalt fiber reinforced composites (BFRP) have been gradually applied to underground civil de-fense projects due to their good mechanical properties. However, protective doors need to meet the filter ventilation and air intake requirements of the project, and it is inevitable that the door body should be processed with openings. A numerical model of a basalt fiber composite door is established by ABAQUS, of which the deformation and stress of fiber composite door in different opening forms are studied. A comparative analysis is conducted on the blast resis-tance performance of basalt fiber composite doors, considering the influence of opening rate and opening position. The opening rate has a certain impact on the performance of fiber composite doors, and the opening position has a great impact on the performance of fiber composite doors.
