Introduction. The impact response of a composite structure consisting of a metal-packaged ceramic interlayer and an ultra-high molecular weight polyethylene (UHMWPE) laminate has been studied through a ballistic test and numerical simulation. Let’s look at the properties of ceramics, polymers and composites. 1. Chemical stability under high temperature and irradiation coupled with high specific. Figure 28 shows typical mass requirements of RHA and ceramic composite armour to defeat 12. Introduction.
