Wind Turbine Blades

Rifeng® PMI structural foam cores for Wind Turbine Blades


Due to the high maintenance cost of large wind turbine blades and the increasing dimension of wind turbine blades. We need to use advanced composites with high stiffness, strength and good fatigue property, while reducing the weight of blades.


Onshore turbine blades are typically produced in lengths of up to 60 meters, while offshore turbine blade lengths can be in excess of 80 meters. Wind loads in structures of this size are extreme and, in turn, establish high structural requirements for the other wind turbine components from the blade bearing to the tower foundation. A reduced weight blade and good fatigue properties can have a substantial impact on lessening the stress on turbine components and extending the turbine life.


High cost-effective Rifeng® PMI foam is committed to reducing production costs and improve installation efficiency of wind turbine facilities to promote wind energy with the advantage of technology and business.


Rifeng® plays a key role in reducing the overall blade mass and resin costs because of its low density and closed cell properties that minimize resin uptake during the infusion process used to create the finished blade. By using ultra-lightweight Rifeng® foam cores, blade manufacturers are able to employ an optimized infusion process with reduced cycle times and increased quality levels, as compared to typical other material system solutions.
