Repair of Sandwich Material
Two types of core materials are used for sandwich on the
EXTRA 330LX:
-
PVC hard foam
-
Honeycomb
both with glass or carbon fibre shells.
The following section describes the repair of both types of
sandwich. Different processing techniques for these mate-
rials, if necessary, are also described.
a) Minor surface damage
Around a visible crack, the laminate may be separated from
the core material. Determine the extent of this area by coin
tapping. Remove the separated laminate carefully using a
sanding disk, sanding block or a sharp knife. Prepare a
scarfed overlap of the laminate around the damaged area.
Overlap length per fabric layer min. 20 mm;
I M P O R T A N T
Ratio (laminate thickness : overlay length) min. 1: 50
(refer to Figure 5).
Figure 5
Minor surface damage
After preparing the scarfed overlap, clean the repair area
thoroughly as follows:
1
Remove the sanding dust with a pneumatic vacuum
cleaner
2
Clean the scarfed overlaps with carbon-tetrachloride or
acetone in case of dirt or grease was introduced during the
preparation.
Damaged core material has to refilled with a mixture of resin
and microballoons (weight ratio 100:15). Apply resin mix-
ture to the repair area and lay on fabric in accordance to the
