Quality assessment of textile composites needs to have sufficient knowledge about the various types of non-destructive testing techniques to detect defects as well as the effect of these defects on mechanical performance. The paper aims to discuss these issues.
The major approach of this paper was to evaluate the potential of two inspection techniques named ultrasounds, vibrations for detecting textile reinforcement defects in composites and evaluate the composite performance in the presence of a damage.
Potential solutions have been identified to solve the issue of signal attenuation observed during C-scan ultrasonic testing, and the criticality of initial defects on static test was determined.
The research work presented here has been a first attempt to apply the combination of different techniques in particular polar scan for the textile composite inspection. This will become more crucial as requirements for high performance and complex shape textile composite parts.
The facilities required for this research were provided by several research laboratories at École de technologie supérieure and at the National Research Council, Canada. In particular, the authors would like to acknowledge the help of Mr M. Corbin. The support of JB Martin (St-Jean-sur-le-Richelieu, QC, Canada) with providing the reinforcement fabrics is also greatly appreciated.
