• TYCOR® W combines glass fibres with closed-cell, low density foam in an engineered architecture
• Direct core replacement for balsa wood, PVC and SAN foam in blades
• Used in GL approved utility scale wind turbine blades
• Twenty five millimeters thick (one-inch) TYCOR® W saves 2.44 kg/m2 of weight (0.5 pounds per square foot) and reduces resin usage by 1 kg/m2 (0.2 pounds per square foot) when compared to 25 mm (one-inch) thick coated balsa
• Unique internal fibre architecture enhances uniform resin flow for reduced resin usage and controlled infusion
• Optimised sheet sizes improve kitting yield over balsa wood and foam cores by as much as 10 percent
• Larger sheet size means fewer core segments are necessary to load large turbine blade moulds – reducing the number of core joints and enhancing core fit at adjoining segments

Efficient Kitting and Infusion

• Designed for Vacuum Infusion or VARTM process
• TYCOR® W cores are highly contourable and flexible, absorbing less resin in curved and flat parts
• Superior durability for kitting and handling
• Easy to cut, kit and shape with standard saws and knives
• Available in 13 to 78 mm thickness range
• Standard sheet size: 1120 x 2225 mm; custom sheet sizes available
• High volume capacity, just-in-time delivery, ISO 9001 certified

TYCOR® W Saves Weight and Cost

Infused TYCOR® W is significantly lighter than infused coated balsa and structural foam and uses less resin. For wind turbine blade builders and infusion moulders, TYCOR® W’s ability to save weight and reduce resin usage offers measurable cost efficiencies. Weight data (below) was measured by WebCore using 25.4 mm thick cores vacuum infused with polyester resin. SAN foam (70 kg/m3) featured narrow contourability cuts for blade shells. Nominal balsa density is 150 kg/m3.
