hi.composite Blade Repair
Rotor blade repair fast, efficient and almost weather-independent.
Innovative technology for repairing almost any damage to the rotor blade surface
Through the combination of heat and vacuum and the use of modern PrePreg materials, hi.composite Blade Repair is an innovative and efficient system for faster repair of damage to rotor blades
Save costs and time
up to 65% less plant downtime due to faster repair thanks to innovative technology
thanks to standardized work steps, certified materials and process monitoring
Longer repair season
almost weather-independent, usable from 0°C and at humidity up to 100%
For many claims
applicable for almost all surface and structural damages as well as in the interior of rotor blades
Less waste thanks to precisely metered resin quantities and elimination of additional disposable materials
Consistently high quality through use of GL-DNV certified materials and electronic monitoring
the components are longer and easier to store and transport than conventional prepegs
The principle: fast and simple thanks to standardized work steps, certified materials and monitoring
Prepare damage site
Cleaning and grinding of the damaged area (up to 1.5 square meters)
Cut hi.composite patch from pre-impregnated glass fiber or carbon fabric and position on the damaged area, if necessary several layers
hi.compositeMat fix over the patch
Fix hi.composite Mat airtight over the patches with double-sided tape and connect to hi.composite Unit.
Cure with hi.compositeUnit
The hi.composite unit provides heat and vacuum underneath the hi.composite mat, the hi.composite patch cures within 45 minutes
Individual surface finish
Seal surface accordingly analogous to existing rotor blade finish
Your advantages in detail
Up to 50 % cost savings:
the system reduces curing time and thus plant downtime by up to 65 %. Costs can thus be reduced by up to 50%.
High, consistent quality:
GL-DNV certified materials and electronic process monitoring guarantee the highest quality at all repair stations.
Longer repair season:
the combination of vacuum and heat removes moisture from the repair area - repairs can be made from 0° Celsius and up to 100 % humidity.
less waste due to exact cutting and thus precisely metered resin quantity. Disposable materials such as vacuum bagging film, evacuation fabric and resin containers are eliminated.
Ease of use:
standardized work steps, certified materials and process monitoring enable repairs even for employees with a lower qualification matrix.
Compared to conventional prepregs, hi.composite materials are easier and longer to store and easier to transport
For all surface damage:
A hi.compositePatch is highly flexible and allows repairs to be made to the entire surface of the rotor blade as well as to the interior of the rotor blade.
Possible time saving
Total working time
* without device workplace (stage or rope access)
Cost reduction potential
Wage costs team 2AK*
Downtimes of the WTG**
Total working time
* No complete supervision of the annealing process and excluding incidental costs, expenses, lodging, set-up time, etc.
** 4 MW plant and feed-in tariff of 0.09 €/kWh
All in One: The hi.composite Blade Repair System
Structural repair sheets with fast curing epoxy prepreg system, customized available as glass fiber or carbon with unidirectional or multiaxial fiber
Generates temperatures up to 120°C and a vacuum over the repair area. The hi.compositePatches thus cure quickly and with a high fiber volume on an area of up to 1.5 square meters.
The basic unit contains a vacuum pump and the power supply for the hi.compositeMat. Curing can be monitored via the integrated temperature control.
The Pro unit additionally allows control programming incl. parameter documentation and thus guarantees reliable process monitoring, optionally with online query.
