Mechanical characteristics of C-SiC composite dual-wall shield structure subjected to hypervelocity impact

C-SiC composite is a new type of material which is being developed with aerospace technology. C-SiC composite possesses excellent properties and can satisfy the requirements of spacecraft protection system. Therefore it is very significant to study the mechanical behavior of C-SiC composite subjected to hypervelocity impact. Based on current simulations and experiments about C-SiC composite, a set of parameters which are essential for simulating C-SiC composite subjected to hypervelocity impact are derived in this paper. The characteristics of C-SiC composite dual-wall shield under hypervelocity impact and its ballistic limit curve are obtained by numerical simulations with AUTODYN, and furthermore, the ballistic limit equation is also developed.
