波阻抗梯度飞片材料及其在动高压物理中的应用

Flier-plate Material with Graded Wave Impedance and Application in Dynamic High-pressure Physics

波阻抗梯度飞片材料是一类新型的功能梯度材料（FGM）,它是FGM在动高压物理领域内的功能延伸.利用波阻抗梯度飞片材料可以实现对靶材料或二级飞片的准等熵压缩和超高速发射,进而能够在实验室条件下获得相当于核爆水平的极端超高压状态,从而为核武器的设计和武器物理研究提供了现实、可行的研究手段.

Flier-plate Material with Graded Wave Impedance is a new kind of Functionally Graded Material (FGM), which may be applied to dynamic high-pressure physics. By using such flier-plate material, quasi-isentropic compression to target material or projectile can be realized, and based on it hypervelocity launching of projectile is further accomplished. As a result, extremely high pressure equivalent to nuclear explosion can be obtained in the laboratory, which offers a practical and feasible method for the design of nuclear weapons and the researches on weapon physics.
