Abstract
A method of manufacturing a wind turbine rotor blade part, the method including: providing a placeholder including a core member and a sleeve, wherein the core member defines a longitudinal direction and has a circumferential surface, a front end and a back end, and the sleeve includes a peel ply layer, wherein the sleeve covers the circumferential surface and the back end of the core member and is affixed to the back end of the core member; arranging the placeholder together with reinforcing fibers and a matrix material in a mold; curing of the matrix material, so that the placeholder is embedded in a fiber-reinforced composite material.

A method of manufacturing a wind turbine rotor blade part, the method comprising:
- providing a placeholder including a core member and a sleeve, wherein the core member defines a longitudinal direction and includes a circumferential surface, a front end surface, and a back end having a back end surface, and the sleeve includes a peel ply layer, wherein the sleeve covers the circumferential surface and the back end surface of the core member and is affixed to the back end surface of the core member;
- arranging the placeholder together with reinforcing fibers and a matrix material in a mold;
- and,
- curing of the matrix material, so that the placeholder is embedded in a fiber-reinforced composite material.
