满足其在工作环境下既能承受一定的压力不漏气又能在较小的顶破载荷下自行破裂的设计要求。

Analysis and Design of The Structure Layer of The DirectionalDamage Composite Laminated Shell

A new kind of structure of the directional composite laminated shell structure is designed in this paper,

based on the composite laminated plate as the basic matieral. The weakness is precasted in the missile and the initial

contact area of the shell structure precast defect area. The missile launch cracking in the form of four petals,and

the efficiency of the missile launch is improved greatedil. Through the finite element simulation analysis software ANSYS,

the design scheme of the layer is determined by the strength analysis, namely 0. 2 mm of the thickness for the

single plate,the weakness is strengthen using the matrix itself,the kinds of the layer methods for 0°/90°/ ±45°]2S,

the limit load is 0. 21 MPa and the minimum bursting load is 1 kN of the layer, so that it can meet the design requirements

to bear certain internal pressure and in smaller bursting load to crack in the work environment.
