9-23. Armor Plating. The repair instructions that follow
are limited to composite armor composed of a ceramic
facing bonded to a fiberglass reinforced plastic backing.
The ceramic facing is covered with a flexible spall shield
to protect the crew members from ballistic fragments. A
rubber molding is also provided on the edges of some
panels for crew protection. These repair procedures were
developed with the objective of matching, to a high
degree, the original strength and ballistic properties of the
undamaged armor panel, with a minimum increase in
weight. Extending the service life of armor panels will
facilitate the mission capabilities of organizational units by
the effective use of material assets. The ceramic facing
may consist of one of the following materials.
Aluminum Oxide (AI203)
Boron Carbide (B4C)
Silicon Carbide (SiC)
Armor Plating Inspection and Repair Definitions.
Table 9-6 gives definitions relative to inspection and
Radiographic inspection of the assembled armor panel is
the primary method used for nondestructive testing in
determining the extent and location of internal damage.
The radiographic skills and equipment required for this
type of testing, while available at Depot installations, are
not available to Army field units. Therefore, for field
units, a visual inspection of the panels must be made,
which requires removal of the nylon spall shield. Remove
the edge molding and peel off the nylon spall shield.
Exercise care when removing the spall shield to avoid
damage to the cloth. Use the following inspection
