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, 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;
- and,
- curing of the matrix material, so that the placeholder is embedded in a fiber-reinforced composite material.
A placeholder for being embedded in a fiber-reinforced composite material of a wind turbine rotor blade part, the placeholder comprising:
- a core member defining a longitudinal direction and including a circumferential surface, a front end, and a back end;
- and,
- a sleeve including a peel ply layer, wherein said sleeve covers said circumferential surface and said back end of said core member and is affixed to said back end of said core member.
