Abstract:
A method for testing a component for contamination. The method comprises a heating of a specimen surface of the component under a measuring bell defining a measurement volume, an at least two-time measuring of a contamination of the measurement volume with at least one contaminant, and a purging of the measurement volume with gas. An apparatus for testing a component for contamination is also disclosed. The apparatus comprises a measuring bell configured to form a measurement volume about the component or contacting the component. A heating element is configured to heat at least one specimen surface of the component. A purging unit is configured to purge the measurement volume with gas. A sensor system is configured to measure a contamination of the measurement volume with at least one contaminant.
Abstract:
The disclosure herein relates to a measuring system for determining damage to components including at least one fiber-reinforced plastics material, comprising sensors that can be or are arranged on a component to be mutually spaced, the sensors distributed over a curved surface of the component in the use position. In order provide a measuring system by which it is possible to obtain fiber-reinforced plastics components economically and with reasonable outlay, and by which process parameters and/or state variables can be reliably obtained during production and operation of the component, it is proposed to provide the component with a substrate that is different from the component and on which the sensors can be or are arranged, the substrate being flexible, and for the sensors arranged on the flexible substrate to form a measuring device.
Abstract:
A measurement arrangement for detecting damage to components that are made of at least one fiber-reinforced plastic material, has a plurality of temperature sensors that are arrangeable or arranged on a component at a spacing from one another. In order to provide a measurement arrangement, by means of which temperature data can be cost-effectively obtained during the production and operation of a component and for it to thus be possible for damage to the component to be recorded and monitored, the plurality of temperature sensors on the component form a sensor array and a change in the thermal material properties of the component is detected by means of the sensor array.
Abstract:
An apparatus used for the surface examination of components. The apparatus comprises: a radiation source configured to convert at least one non-volatile substance at least partially into a gas by irradiating a sample surface of a component; and a detector unit configured to qualitatively and/or quantitatively detect the at least one substance converted into gas. A method provided for a surface examination of components. The method comprises irradiating a sample surface of a component with a radiation source configured to convert at least one non-volatile substance at least partially into a gas; and a qualitative and/or quantitative detection of the at least one substance converted into gas via a detector unit.
Abstract:
A device used to examine layer material for contamination. The device comprises a heating device to heat a test area of the layer material and a detector device to detect at least one contaminant desorbed from the layer material. The heating device comprises at least one infra-red heating element. A method comprises heating a test area of the layer material and detecting at least one contaminant desorbed from the layer material. The heating takes place via an infra-red heating element.
