Stiffening component and method as well as combing tool

摘要

An arrangement for monitoring the functionality of a structural adhesive layer to be fabricated between a first surface of a stiffening element and another component. A sensor block is bonded to a second surface of the stiffening component opposite to the first surface. The area of the structural adhesive layer incorporates a plurality of air openings and vacuum openings that vertically extend through the stiffening component and structural adhesive layer and the sensor block. The air openings are interconnected among each other by at least one air channel, and the vacuum openings by at least one vacuum channel. At least one of the channels is connected to an evaluator unit to detect a failure of the structural adhesive layer.

1. An arrangement for monitoring the functionality of a structural adhesive layer fabricated between a first surface of a stiffening component and another component, comprising:
the stiffening component; the structural adhesive layer fabricated between a first surface of the stiffening component and another component; a sensor block bonded to a second surface of the stiffening component opposite to the first surface; and a plurality of air openings and vacuum openings vertically extending through the stiffening component the structural adhesive layer and the sensor block, wherein the air openings are interconnected among each other by at least one air channel, and the vacuum openings are interconnected among each other by at least one vacuum channel, and wherein the air and vacuum channels extend in the sensor block, and wherein the channels pneumatically operatively interact with the structural adhesive layer between the stiffening components and another component by way of the air and vacuum air openings, the arrangement further comprising an evaluator unit connected to at least one of the channels to detect a failure of the structural adhesive layer, wherein the arrangement further comprises a combing tool having a plurality of borehole pins which are spring-mounted in bearing boreholes of a housing, wherein the combing tool is configured to be inserted into the stiffening component such that the borehole pins penetrate through the structural adhesive layer and scratch a surface of the additional component.
