respectively. The chemical components as well as the distinguished physical properties, e.g., high hardness and compressive strength, low density and small thermal
expansion, are listed in Tables 7.2 and 7.3, respectively.
As shown in Fig. 7.2b, a Q235 steel frame was bonded to the SiC plate with epoxy
resin for the convenience of assembling the composite plate. The fixation of the
composite plate is further illustrated in Fig. 7.2c in which the SiC ceramic plate with
steel frame was fixed to the 10CrNi3MoV21A armor steel plate with twelve bolts.
