panel shape, then the repair to the panel will have to
proceed in stages.
Cut away the damaged areas until the remaining panel
attains its correct contour, then repair the skins in se-
quence in two stages. If the core is damaged over a lar-
ger area, cut away the damaged core and replace it be-
fore repairing the second skin.
51-15-04 - COMMON STRUCTURAL LAMINATE
REPAIR (METAL INSERT)
1. Cut away laminate per Figure 51- 28, roughen repair
area with 240 sandpaper, clean repair area with M.E.K. -
apply a wet coat of catalyzed epoxy resin to surfaces.
Then IMMEDIATELY proceed with steps 2 thru 5.
2. Install chemically cleaned .025 T- 3 aluminum
straps, perforated with #40 holes approximately .35 on
center all directions.
3. Apply wet coat of epoxy resin to aluminum straps
and apply one or more layers of resin saturated #181
fiberglass cloth to equal the thickness of the original
laminate.
4. Lay wax paper over both sides of the repaired area
while still wet. This prevents adhesion to the pressure
clamp application (paragraph 5).
5. Place rigid aluminum plates on both sides of repair
area and clamp into place with “C” clamps. Permit lami-
nated repair to cure.
6. After fiberglass repair has cured, remove clamps
and install #3 AN426A rivets. Flush heads to be on fin-
ished surface side. Number of rivets and spacing will be
determined by size of repair.
7. Apply one additional overlapping layer of #181 fi-
berglass cloth on non- finished surface and bond in
place. Should opposite side be a non- finished surface,
an additional layer of fiberglass should be applied to
this side.
8. Upon completion of steps 1 thru 7, permit repair to
cure before attempting further treatment of appearance
surfaces, if required.
9. Appearance surfaces will normally require ap-
plication of a filler- sealer coating. Appearance area is
to be wiped clean, using a clean cloth saturated with
M.E.K. prior to applying filler- sealer coating.
10. Mix epoxy resin and catalyst per manufacturers
specifications and apply to appearance surface area.
Care should be taken to assure as smooth as possible
surface in this particular operation.
Permit this surfacing coat to cure prior to any additional
applications or further rework.
-CAUTION-
When sanding and working with fiberglass,
wear full eye- protection, ear- protection and a
respirator or mask to protect you from airborne
fiberglass particles.
11. Using #240 sandpaper, sand and blend repaired
area to match surrounding surface. Steps 10 and 11
may be repeated to acquire a satisfactory surface
finish.
