COMPOSITE CURING
WIND POWER TURBINE BLADE REPAIR
An ideal way to repair power turbine blades
Application
Wind power turbines (windmills) have become a popular renewable energy source
used to generate electricity. The modern windmill is equipped with large airfoil
shaped propeller-like blades that are constructed using lightweight high strength
composite fiber materials. The high strength and lightweight features allow the blades
to efficiently capture wind energy and convert it into electricity.
Over time, the wind turbine blades can develop small cracks and holes on their
surface and repairs must be made before catastrophic damage results. Heat and
vacuum pressure is required to repair composite blades. Removing these blades
from a wind power turbine can be extremely time consuming and costly, therefore the
ability to make repairs in the field is important.
Solution
Use BriskHeat’s transportable ACR® 3 Hot Bonder or ACR MiniPro Hot Bonder system.
The hot bonder systems include the hot bonder, silicone rubber composite curing
heating blankets, a power booster box, and vacuum bagging material used together to
create a portable repair station.
ACR hot bonders are a portable composite curing/debulking tool that is capable of
creating its own vacuum pressure and regulating heat using programmable ramp/
soak cycles. It records cure data that can be downloaded via a built-in USB port and
retained for quality assurance records. The ACR hot bonders electronics are enclosed
within a virtually indestructible, impact resistant, waterproof, Pelican ® case for easy
transport and worry-free protection.
Silicone composite curing heating blankets provide fast, uniform, and consistent heat
in an extremely durable and flexible design. The extreme flexibility ensures ultimate
surface contact across the entire repair surface. BriskHeat also offers vacuum bag,
breather cloth, release film, and sealant tape materials used to create a field ready
vacuum chamber for the repair.
Often a power booster box is necessary to increases voltage and amperage of up to
480VAC 3-phase and 100 amps. The increased voltage and amperage is required for
large curing applications where power cord assemblies must be long enough to reach
the required height of a blade assembled on a wind power turbine.
