Scope

This document describes a mechanical impedance detection method for the internal quality of resin-based composite parts based on acoustic vibration detection, and specifies the general requirements, detection steps, detection records, and reports for the mechanical impedance detection method.
This document is applicable to the detection of delamination or debonding in resin-based composite parts such as laminated structures, bonded plate/plate structures, and sandwich structures made of carbon fiber, glass fiber, and mixed fiber materials. The mechanical impedance method for detecting other materials or structures should be implemented with reference to this document.
