Abstract
A method of detecting delamination of a composite component, the composite component having a plurality of plies and a plurality of z-pins extending through the composite component in a direction transverse to the plies. The method includes measuring one or more material properties of one or more of the z-pins. The measured material properties are compared to reference material properties. An estimation of whether delamination has occurred is performed based upon the comparison of the measured material properties and the reference material properties.
Claims17
A method of detecting delamination of a composite component, the composite component having a plurality of plies and a plurality of z-pins extending through the composite component in a direction transverse to the plies, the method comprising:
- measuring one or more material properties of one or more of the z-pins;
- comparing the measured material properties to reference material properties;
- and
- estimating whether delamination has occurred based upon the comparison of the measured material properties and the reference material properties.
A system for detecting delamination of a composite component having z-pins, the system comprising:
- one or more measurement arrangements configured to measure material properties of one or more z-pins of a composite component;
- a data processing unit configured to:
- receive a signal from the one or more measurement arrangements;
- compare data from the signal to one or more reference parameters;
- estimate whether delamination of the composite component has occurred based upon the comparison of data from the signal to one or more reference parameters.
