Non-destructive testing of acoustic emissions from fiber-reinforced polymers
Testing methods and evaluation criteria
1 Scope
This document describes the general principles for acoustic emission testing of fiber reinforced polymer (FRP) components and structures. Materials used in FRP
Performance characterization and verification tests, manufacturing quality control of components and structures, online testing of service performance, and health monitoring, etc.
This document describes the use of acoustic emission techniques to assess the integrity of fiber-reinforced polymer components or structures or to identify severe
Specific methods of accumulating damage or aggravating damage to major areas.
This document describes the general FRP acoustic emission detection and evaluation criteria and gives the procedures for establishing the evaluation criteria.
This document provides a qualitative evaluation criterion format for acoustic emission test data in online inspection and post-analysis, for different test locations.
Simplified comparison with the acoustic emission test results obtained by the testing agency brings convenience.
Note. Structural integrity evaluation based on acoustic emission cannot be evaluated solely based on the evaluation criteria given in this article. In many cases, further testing and testing are required.
Evaluation (e.g. using other non-destructive testing methods or fracture mechanics calculations, etc.).
