DETAILS
*Greater efficiency in wind turbine production
*Asia´s first rotor blade made of polyurethane
*Major breakthrough in China with new resin system
Covestro has now manufactured
the first polyurethane rotor blade
for wind turbines in Asia.
The 37.5 meter-long rotor blade,
which is designed for a wind turbine
with an output of 1.5 megawatts,
was fabricated with
* a special polyurethane infusion resin from Covestro and
* glass fiber mats from
Chongqing Polycomp International (CPIC),
a leading Chinese glass fiber manufacturer
at the Shanghai FRP Research Institute.
A vacuum pressure infusion system
with continuous degassing, developed by
process technology specialist HÜBERS,
was used to produce the rotor blade.
Kim Klausen,
Global head of the Wind Energy Program at Covestro
“It's further proof of the performance and
cost advantages of polyurethanes over epoxy resins
in wind power generation.”
The polyurethane resin has very good physical properties,
an excellent flowability and it thoroughly wets
the glass fibers. Furthermore, less thermal energy
is released during its processing than with epoxy resins.
