The invention relates to a method for producing a fiber-composite hollow component from a fiber-composite material which contains at least one fibrous material and one matrix material, wherein the fiber-composite hollow component is formed from at least two fiber-composite half-shells which in a joining edge region of the fiber-composite half-shells are joined to one another such that a cavity is configured between the joined-together fiber-composite half-shells, wherein the method comprises the following steps: providing a first fiber-composite half-shell formed from the fibrous material of the fiber-composite material, and at least one second fiber-composite half-shell formed from the fibrous material of the fiber-composite material; assembling the first fiber-composite half-shell and the at least second fiber-composite half-shell so as to form the fiber-composite hollow component; wherein at least one spacer element is inserted in the joining edge region between the first fiber-composite half-shell and the at least second fiber-composite half-shell; incorporating an internal vacuum cover in the cavity formed by the assembling of the fiber-composite half-shells, and incorporating the assembled fiber-composite half-shells in an external vacuum cover such that a component cavity having the fibrous material of the fiber-composite hollow component to be produced is formed between the internal vacuum cover and the external vacuum cover; evacuating the component cavity having the fibrous material; and curing the matrix material which embeds the fibrous material of the fiber-composite half-shells, in order for the fiber-composite hollow component to be produced.
A method for producing a fiber-composite hollow component from a fiber-composite material which contains at least one fibrous material and one matrix material, wherein the fiber-composite hollow component is formed from at least two fiber-composite half-shells which are joined to one another in joining edge regions of each of the two fiber-composite half-shells such that a cavity is configured between the two fiber-composite half-shells when they are joined together, comprising:
The method of claim wherein the at least one spacer element is/are formed from a fibrous material of a fiber-composite material and the at least one spacer element is/are inserted in the joining edge region, wherein the matrix material embedding the fibrous material of the fiber-composite half-shells and the fibrous material of the at least one spacer element is cured in one process step.
