One of the major challenges in textile composites is the verification of their manufacturing quality, which has large influence on the mechanical properties. Quality assessment of these composites needs to have sufficient knowledge about the various types of nondestructive techniques and their inspection. The aim of this article is to evaluate the potential of three inspection techniques named ultrasounds, vibrations, dimensional measurement for detecting textile reinforcement defects in composites. The research work was focused on two types of defects, namely fiber/yarn breakage and ply misorientation, applied to woven textiles composite produced by vacuum assistant resin transfer molding. Fabric misorientation appeared to have an influence on the dynamic behavior of the textile composite samples. Potential solutions have also been identified to solve the issue of signal attenuation caused by the fabric observed during conventional and polar ultrasonic C‐scanning. A closer look at plates surface around eliminated unit cells by coordinate measuring machine at mesoscale did not appear any specific abnormality on due to artificially induced defect. POLYM.
