Cyclics Corporation targets wind turbine blade manufacturers

28 June 2001


Cyclics Corporation’s innovative thermoplastic resin could radically increase the manufacturing rates of large wind turbine structures, typically made of thermoset composites. The low viscosity thermoplastic CBT resin flows easily and processes like thermoset resins. Increased production rates are possible as Cyclics’ CBT resin can cure in well under one hour, even in thick sections, because CBT resin does not generate heat during curing and can be processed at constant temperature. That removes the curing cycle as the bottleneck in rotor blade manufacturing enabling several blades per tool to be made each day. Once processed the blade can be assembled and finished using traditional techniques.

Another key benefit of CBT composite wind turbine structures is the environmental friendliness, in addition to being recyclable, they do not cause any VOC (out-gassing) during processing. The final mechanical part properties are comparable or superior to standard thermoset systems.

“Further testing and certification is underway and qualification is anticipated within in the next 6 months,” said Roman Eder, Managing Director of Cyclics Europe GmbH. Processing options include but are not limited to resin infusion molding, filament winding, liquid molding techniques like vacuum assisted RTM and various prepreg-processes.

“We are extremely encouraged by the initial results and are gearing up our production to meet the demand of this growing market,” said John Ciovacco, CEO of Cyclics Corporation, ”Wind power is an exciting global market and we are proud to offer environmentally friendly products to meet critical energy demands.”

Cyclics Corporation is commercializing an innovative plastic that is a breakthrough in processing making new products possible and changing the economics of existing ones. They offer the processing advantages of a thermoset, namely the low viscosity, but have the material properties of a thermoplastic when polymerized. Cyclics products include low viscosity forms of popular polyester thermoplastics. Since the founding of the company, the Cyclics Corporation has received hundreds of inquiries in areas, such as structural composites and compounding, where the water-like viscosity of these cyclic materials allow for extremely high filler volumes and unique polymer chemistries.
