Porosity and voids

Evidence of porosity can be detected in a number of ways including simple A-scan measurements through to detailed B-scan and C-scan analysis of the ultrasound echo position and amplitude.

Wavelength NDT can help you develop porosity analysis methods suitable for your product and application.  This can be simple measurements of ultrasound attenuation through the laminate through to fully calibrated porosity assessments and percentage void calculations.

Focussed ultrasound B-scan and C-scan inspection of voids permits enhanced analysis of defects to help ascertain the nature of the void such as laminate contamination, dry fibres, bridging or layer porosity.
