Abstract
Investigation into the production flaws in thin solid carbon laminates by using the ultrasonic phased array method
Highlights
Composite materials are made by combining two or more base materials with significantly different properties, which, after being combined, have unique properties different to those of base components
The inspection of carbon fibre reinforced polymer (CFRP) components with Ultrasonic testing (UT) is subject to strict requirements in terms of ensuring reliable and time efficient non-destructive testing (NDT)
The majority of these difficulties can be overcome by using phased array ultrasonic testing (PAUT), involving signal processing and correction with advanced algorithms, such as the threshold modified S-transform (TSMT), combined with multiple pulser-receiver elements working together [5,6,7,12]
Summary
Composite materials are made by combining two or more base materials with significantly different properties, which, after being combined, have unique properties different to those of base components. Along with the increased use of composites, multiple NDT methods have been further developed for examining them. Ultrasonic testing (UT) is a well-established technique based on the vibration of materials It can be used for both composite and metal structures. Examining composites carries some major technical challenges such as the attenuation, scattering and absorption of the signal and the shadowing effect of multiple damage can have an influence on the received results The majority of these difficulties can be overcome by using phased array ultrasonic testing (PAUT), involving signal processing and correction with advanced algorithms, such as the threshold modified S-transform (TSMT), combined with multiple pulser-receiver elements working together [5,6,7,12]. In order to do this, several methods have been used, as described in the following chapters
