The wing consists of a one-piece, dual chamber main spar
with carbon fibre roving caps and carbon fibre webs. For
the spar core PVC foam is used. The wing shells are a
honeycomb sandwich construction with carbon fibre lami-
nates. To prevent buckling of the shells, plywood ribs are
used.
The layer sequence of the wing is shown in Figure 1.
All composite parts, as protection against moisture and UV
radiation, are coated with an unsaturated polyester gel-
coat, an acrylic filler and finally with an acrylic paint.
For repair of composite parts refer to Chapter 51.
