Heating Blanket for Advanced Composites
Description
With their patented and innovative heating blanket solutions, Veelo Technologies helps composite rotor blade manufacturers and repair facilities keep blades out of the oven (OoO). Veelo’s heating blankets can be tailored for use in debulking and bonding applications and can be used in-situ, eliminating the need to transport long and bulky rotor blades to an oven. Eliminating that transportation step helps improve build and repair rates while reducing scrap.
Due to their uniquely flexible and pliable design, the heating blankets are highly drapable and provide uniform heating coverage across the large and geometrically complex surface areas found on rotor blades. Veelo heating blankets easily accommodate custom shapes and large tools with minimal or few bridging issues. They are durable and damage resistant and are offered in an optional FKM-based heater system for high performance and material compatibility.
Veelo heating blankets are controlled by the VeeloHEAT Controller, a cost-effective solution capable of controlling systems that can be adapted to the end-use application with 16 or more output channels. The digital IoT controller can store data and receive updates locally or via the cloud and is highly customizable.
VeeloHEAT is currently used by the aerospace composites industry to bond multi-million-dollar composite aerostructures, accelerating adhesive cure, composite repair, improving heated debulk processes, and heated tooling.
