Figure 7-11. Weight Versus Hole Diameter for Two Core Replacement Methods
c. Core Potting and Replacement. Core potting is
the process of illing the core cutout with a curable
paste iller material. If the damage is sustained in
an area with an already potted core, the replacement
core ply should also be potted. If honeycomb or
foam core is damaged, it may be potted rather than
plugged if the damaged area is usually smaller than
1.5 inches in diameter. Refer to the system speciic
technical manual for damage limits. For damage
beyond this limit, repair the damaged core using
paragraph 7-5d, paste adhesive method. Figure 7-11
shows typical weight gains using core potting. Figure
7-12 shows the process low. This repair procedure
is not necessarily applicable to a particular weapon
system. The applicability of this repair depends
upon additional factors such as loading conditions
and laminate thickness. Consult the system speciic
technical manual or engineering for further guidance.
