Analysis For The Explosion Resistant Capability Of CBF Ship

The continuous basalt fiber(CBF) reinforced composite, which is a kind of new composite by using basalt fiber as intensifier, is made from basalt ore which is broken, melt and extended into continuous fiber. The CBF composite material has excellent capacity, the ship structure made by CBF materials is lighter, harder, more anti-corrosive than the structure made by steel, what's more, CBF is cheaper than carbon fiber material which has similar capability to CBF, has very excellent future.Nowadays, during to the development of anti anti-warship weapons, a warship involved in a battle will encounter threaten from the explosion in the air and under water, which may weak or even deprive its combat capacity and survivability. Therefore, it is of great practical engineering significance to make extensive research on the destructiveness of non-contact explosion, to predict in the designing process the ship structure's response to it, thus elevating the survivability and combat capacity of the ship.The thesis mainly studied the explosion resistant capability of CBF materials. The basic theory of the laminate composite and explosion is introduced. The CBF materials ship superstructure's response subjected to air non-contact explosion was analyzed by FEM software Dytran, multiple Euler domains are used to simulate the air inside the structure, the surrounding air and the explosive, the broken of the superstructure and the pressure change of the air inside and outside the structure were studied. The dynamic response of a CBF laminate ship section under underwater explosion and explosion pulse load was calculated, phenomena of underwater explosion bubble pulse was simulated, the response value was compared with the results of ship section made of E-glass fiber reinforced composite. The results show that forms of the destroyed ship structures made of basalt-fiber laminate and E-glass fiber laminate are similar, the abilities of CBF composite is better than traditional glass-fiber reinforced composite and the CBF composite is capable to instead of latter in shipbuilding.At the end of the thesis, a second time development for Patran was done by applying PCL combined with session file, a simple parameterized model of a ship section was established, a visible interface was developed by using PCL, and the visible interface realized that the design variable, such as dimension, number and location of frames, could be changed.
