Composits
We use special technology for strengthened
the spars in the models. To achieve most
strength we prepare plates of carbon ith
special epoxis. Carbon fibre is a micro
pipe. That's why it is necessary to use
special solvents for epoxi to saturate
carbon fibre better. We make longerons in
the special molds by the temperature of
150C and for this purpose we use epoxis
that are used in aero-space technologies.
We create pressure to the carbon by screws
and in addition silicon expands and create
pressure of 30-50 Bar (Pic.2). Thus
received plates we glue to the balsa of
vertical direction with epoxi L-285. We
wind around the longeron with the kevlar
thread to improve reliability. We make
carbon pipe for the wing joiner than
polish it with the sandpaper, glue into
the longeron and wind around with the
kevlar thread.
We produce D-Boxes for models of
classes F1А-F1J, F3J, F3K.
Besides we produce Carbon-Plates, which
can have any sizes, necessary to you, for
spars and other supporting
structures.
