The materials are assigned as two
different types of glass fabrics, polymeric foam core material and the
steel-balsa wood combination for the root connection parts. The glass
fabrics are applied using hand wet lay-up lamination with epoxy resin
as METYX L600E10C-0, is the unidirectional continuous fibres and
METYX XL800E10F having a tri-axial architecture with fibres in the
0,+45,-45 degree orientations in a ratio of 2:1:1. Divinycell H45 is
used as the polymeric foam.
