Method for reinforcing a fiber composite component and arrangement for producing a reinforced fiber composite component

Abstract

A method and an arrangement for reinforcing a fibre composite component for the aviation and aerospace industry, in which a reinforcing element having a receiving region and a pressure element adapted to the receiving region geometry. The pressure element is inserted into the reinforcing element receiving region. The reinforcing element and the inserted pressure element are fastened relative to one another in a reproducible manner by a reversible fastening device. The fastening device includes a first fastening portion mounted on the pressure element and a second fastening portion which can be mounted on the reinforcing element. The reinforcing element, with the pressure element, is then applied in a reproducible manner to the fibre composite component to be reinforced, to form a moulding portion. The formed moulding portion is cured to connect the reinforcing element to the fibre composite component. The fastening device and the pressure element are then removed from the fibre composite component.

1 . A method for reinforcing a fibre composite component for the aviation and aerospace industry, comprising the following steps:
 providing a reinforcing element comprising a receiving region and a pressure element adapted to the geometry of the receiving region;   inserting the pressure element into the receiving region of the reinforcing element;   fastening the reinforcing element and the inserted pressure element relative to one another in a reproducible manner by means of a reversible fastening device, the reversible fastening device comprising at least a first fastening portion mounted on the pressure element and at least a second fastening portion which can be mounted on the reinforcing element;   applying the reinforcing element, together with the pressure element fastened thereto, in a reproducible manner to the fibre composite component to be reinforced, to form a moulding portion;   curing the formed moulding portion to connect the reinforcing element to the fibre composite component; and   removing the reversible fastening device and the pressure element from the reinforced fibre composite component.   
     
     
         2 . The method of  claim 1 , wherein after the application of the reinforcing element at least the second fastening portion of the reversible fastening device is removed before the formed moulding portion is cured. 
     
     
         3 . The method of  claim 1 , wherein the second fastening portion of the reversible fastening device is mounted on the outside of the reinforcing element, the reinforcing element being arranged between the first fastening portion and the second fastening portion of the reversible fastening device. 
     
     
         4 . The method of  claim 1 , wherein the reinforcing element and the inserted pressure element are fastened relative to one another in a reproducible manner by applying magnetic forces. 
     
     
         5 . The method of  claim 4 , wherein magnetic forces are applied by means of one or more of permanent magnetic elements and electromagnets. 
     
     
         6 . The method of  claim 5 , wherein the first fastening portion is formed using at least one of a permanent magnetic element and an electromagnet, and the second fastening portion is formed using a ferromagnetic element. 
     
     
         7 . The method of  claim 1 , wherein the reinforcing element and the inserted pressure element are fastened relative to one another in a reproducible manner by means of a reversible adhesive element which is mounted between the pressure element and the reinforcing element, the adhesive element comprising an insert layer which is arranged between the first fastening portion and the second fastening portion of the adhesive element and formed for assisting removal of the adhesive element. 
     
     
         8 . The method of  claim 1 , wherein the reinforcing element and the inserted pressure element are fastened relative to one another in a reproducible manner by means of a device for generating and applying electrostatic charging of the fastening portions.
