Abstract：The impact ballistic performances of stuffed whipple shields with basalt and kevlar fiber clothes are investigated by two-stage light gas gun facilities. Protective performance、damage morphology and mechanism of stuffed material and cabin walls are obtained, compared with the impact limit curve of Nextel/Kevlar stuffed whipple shields. Also, the influences of epoxy resin coating on the protective performance are discussed. The data shows that stuffed whipple shields with basalt and kevlar fiber clothes have excellent protective properties in the high impact velocity. Coating with epoxy resin glue improve the prevention performance. Basalt fibers absorb energy by breaking projectile. Kevlar fibers have plastic deformation and fracture. Melting and carbonation process appear in the hypervelocity regions.
