100 meters wingspan offshore wind mills.
This achievement is possible thanks to the incorporation of glass
fibers in the polymer (epoxy, polyester) constituting the envelope
of the blades. This composite material, which combines lightness,
stiffness and strength, makes this blades able to resist to the
very high constraints due to wind and rotation. Also used for the
making of car bodies and boat hulls, the glass fiber can be dispersed
in the polymeric matrix in the form of chopped fibers, long wires
or glass fabrics. Each wire is made of several thousands of individual
filaments with diameter in the micrometer range. It is coated with
a sizing which supplies chemical compatibility with the resin. see
