    Wood

    The balsa wood is very light. With unique cell structure, light weight and high strength, it is an ideal material for structural sandwich. The balsa wood sandwich material is a structural sandwich material made of balsa wood cross-section. The product undergoes drying, sterilization, splicing, slicing and surface treatment. Its strength and rigidity far exceed those of various foams, and it is one of the commonly used varieties of core materials for wind turbine blades.

    Foam

    The PET foam core material is a thermoplastic renewable polymer foam material with an apparent density of 115kg/m3. It is produced using supercritical fluid foaming technology and the process is clean. It has excellent comprehensive mechanical properties, stable chemical properties, good heat resistance, good dimensional stability, fatigue resistance and processability. It is one of the mainstream varieties of core materials for wind turbine blades.
