Carbon fibre composite composite spar structure of HPP blades (article number 105*5 mm)

Carbon fibre composite spar structure (UKLC) is the main power structural element of a wind turbine blade, manufactured by broaching method from carbon fibre and polyurethane, size 105*5 mm.
The following components are used to manufacture the UKLC:
Carbon fibre; Polyol; Isocyanate; Processing additives; Saw blade fabric; Textured glass fibre.
UCLK is a structure of complex geometric shape, repeating the geometry of the shell of the HPP blade. The structure consists of three pairs of composite spars with non-constant cross-section, variable longitudinal-transverse bends.
