METHOD FOR DETERMINING THE FIBRE ORIENTATION IN A FIBRE-REINFORCED COMPONENT HAVING A NUMBER OF FIBRES DISTRIBUTED IN A LAMINATE MATERIAL

摘要

Method for determining the fibre orientation in a fibre-reinforced component having a number of fibres distributed in a laminate material, whereby the fibres are orientated in at least one defined direction, the method comprising the steps of: a) emitting an ultrasonic signal into the component by means of an ultrasonic transducer, b) receiving a reflected ultrasonic signal by means of an ultrasonic receiver and generating a measurement signal, whereby the ultrasonic transducer and the ultrasonic receiver are disposed in a defined linear relationship, c) determining an information indicating a degree of the fibre orientation in relation to the defined linear relationship of the ultrasonic transducer and the ultrasonic receiver from the respective measurement signal.
