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.
Claims11
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 using a first rotary drive coupled to the first inner element 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 using a second rotary drive coupled to the second inner element in order to wrap the second fiber-reinforced plastics band around the second inner element, wherein the second rotary drive rotates independently of the first rotary drive;
- (c) arranging an intermediate element between the inner elements;
- (d) using a tensioning device to move the first and second fiber-reinforced plastics against the intermediate element, wherein the tensioning device comprises two pressing rollers that are positioned on opposing sides of the intermediate element;
- and
- (e) jointly rotating the intermediate element and the first and the second inner elements about a third axis of rotation using a third rotary drive in order to wrap the first and the second fiber-reinforced plastics band alternately around the first and the second inner elements and the intermediate element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.
