Generally, rotor blades are manufactured as half shells in a laminating process with CRP and GRP mixed construction. Application of a separating layer in the mold is indispensable so the finished component can later be removed from the mold. Conventionally, this is achieved with chemical release agents and has to be applied again after each demolding. In the demolding process, traces of this separating layer are transferred to the component. These must be removed without residue before the subsequent painting.
Plasmatreat has developed a simple and efficient solution for reliable demolding of CRP and GRP components without chemical release agents: the PT-Release process that is used to apply a plasma polymer using Openair® plasma.
