Fiber composite component, apparatus and method for producing a fiber composite component

Abstract

A fiber composite component has two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped. In order to simplify the production of the fiber composite component, a first fiber-reinforced plastics band is wrapped around a first inner element, and a second fiber-reinforced plastics band is wrapped around a second inner element. The first and the second fiber-reinforced plastics band are wrapped alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.

What is claimed is: 
     
         1 . A fiber composite component comprising:
 two inner elements arranged at a distance from one another,   a first fiber-reinforced plastics band wrapped around a first inner element of said two inner elements, and   a second fiber-reinforced plastics band wrapped around a second inner element of said two inner elements,   wherein the first and the second fiber-reinforced plastics band are wrapped alternately around the first and the second inner element in such a manner that a distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.   
     
     
         2 . The fiber composite component as claimed in  claim 1 , further comprising an intermediate element arranged between the inner elements, wherein the first and the second fiber-reinforced plastics band are wrapped alternately around the intermediate element. 
     
     
         3 . The fiber composite component as claimed in  claim 1 , wherein the inner elements each have a rotationally symmetrical form and an axis of rotation. 
     
     
         4 . The fiber composite component as claimed in  claim 3 , wherein the inner elements each have at least one circumferential depression, which depressions axial secure the fiber-reinforced plastics bands. 
     
     
         5 . The fiber composite component as claimed in  claim 1 , wherein each fiber-reinforced plastics band is wrapped around both of the inner elements. 
     
     
         6 . An apparatus for producing the fiber composite component as claimed in  claim 3 , the apparatus comprising: a first rotary drive for the first inner element and a second rotary drive for the second inner element, wherein the first and second rotary drives are attached to a coupling support which is rotatable about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner elements with the distance between the first and second inner elements. 
     
     
         7 . The apparatus as claimed in  claim 6 , wherein the apparatus further comprises at least one pressing roller which constitutes a tensioning device for the fiber-reinforced plastics bands between the first and second inner elements. 
     
     
         8 . The apparatus as claimed in  claim 6 , wherein each fiber-reinforced plastics band is wrapped around both of the inner elements. 
     
     
         9 . A method for producing a fiber composite component including (i) two inner elements arranged at a distance from one another, (ii) a first fiber-reinforced plastics band wrapped around a first inner element of said two inner elements, and (iii) a second fiber-reinforced plastics band wrapped around a second inner element of said two inner elements, wherein the inner elements each have a rotationally symmetrical form and an axis of rotation,
 said method comprising:   (a) rotating the first inner element about its axis of rotation in order to wrap the first fiber-reinforced plastics band around the first inner element;   (b) rotating the second inner element about its axis of rotation in order to wrap the second fiber-reinforced plastics band around the second inner element; and   (c) following steps (a) and (b), jointly rotating the first and the second inner elements about a third axis of rotation in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner elements in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.   
     
     
         10 . The method as claimed in  claim 9 , wherein the fiber-reinforced plastics bands are deposited parallel to one another between the inner elements. 
     
     
         11 . The method as claimed in  claim 9 , wherein the fiber-reinforced plastics bands are deposited between the inner elements in a crossed form. 
     
     
         12 . The method as claimed in  claim 9 , wherein a fiber composite component in an axial direction is divided, after wrapping, transversely to the axial direction into at least two fiber composite components. 
     
     
         13 . The method as claimed in  claim 9 , wherein each fiber-reinforced plastics band is wrapped around both of the inner elements.
