The invention relates to a method for producing a structural element (2) of a rotor blade, in particular of an air, land or water transport means or wind turbine, in which an assembly (6) made of fiber and plastic is introduced into a mould (1) and is subjected to an increased pressure and an increased temperature, in which a mould (1) having at least one recess (5) is used, a reinforcing element is arranged in the recess. It is intended to be able to produce such a structural element in a cost-effective manner. For this purpose, it is provided that the reinforcing element (7) is inserted together with the core (11) into the recess (5), the difference volume between the recess (5) and the core (11) at least in a predetermined region being selected by a predetermined value smaller than the section of the reinforcing element (7) arranged in this region.
说明了一种用于生产尤其空中‑、陆地‑或水上运输工具或风能设备的转子叶片的结构元件(2)的方法,在其中将由纤维和塑料构成的组件(6)放入到模具(1)中,并且加载以增加的压力和提高的温度,其中,使用具有至少一个凹部(5)的模具(1),在该凹部中布置加强元件。旨在能够成本有利地制造这种结构元件。为此设置成,将加强元件(7)与芯部(11)一起放入到凹部(5)中,其中,至少在预先确定的区域中在凹部(5)与芯部(11)之间的差值体积被选择得比加强元件(7)的布置在该区域中的区段小了预先确定的数值。
