“…In order to prevent a complete destruction of construction elements made of composite materials,nondestructive testing (NDT) methods are used to detect impact damage and technological defects. In case of FRP's the following NDT methods are applied: thermography, acoustic emission, computer tomography, computer radiography, ultrasound and penetration testing (PT) [18][19][20]. Selection of a given method is conditioned by the type of composite components, type of defects and their location.…”

This paper discusses the impact resistance of glass-fibre reinforced polymer (GFRP) composites depending on the type of reinforcement -plain or twill weave. The values of impact energy were: 3J, 10J and 15J. Specimens featuring twill weave transferred higher force during the impact as compared with plain weave specimens. It was observed that an increase of impact energy was accompanied by an increase of the disproportion in transferred forces, in favour of twill weave specimens. Impact damage (in both types of weave) occurring as a result of 3J impact was undetectable with active thermography method. The damage area measured by means of active thermography for impact energy values equal to 10J and 15J proved that the type of reinforcement significantly influences the impact resistance of a composite.This has been justified by smaller damage areas with high spot intensity of damage in plain weave specimens and highly dispersed damage with lower intensity in twill weave specimens.

This review introduces several areas of importance in acoustic emission (AE) technology, starting from signal attenuation. Signal loss is a critical issue in any large-scale AE monitoring, but few systematic studies have appeared. Information on damping and attenuation has been gathered from metal, polymer, and composite fields to provide a useful method for AE monitoring. This is followed by discussion on source location, bridge monitoring, sensing and signal processing, and pressure vessels and tanks, then special applications are briefly covered. Here, useful information and valuable sources are identified with short comments indicating their significance. It is hoped that readers note developments in areas outside of their own specialty for possible cross-fertilization.

“…Lower frequency waves, for example, 0.5 MHz, experience lower attenuation and hence yield larger penetration (in (249) up to 220 mm is reported). But the longer wavelengths (eg, 6 mm for 0.5 MHz at 3000 m/s) limit the lateral resolution together with a considerable beam spread over long propagation paths.…”

Because of their unique properties, polymers and polymer–matrix composites pose both challenges and opportunities for nondestructive testing. The increasing use of these materials creates a demand for nondestructive verification of various properties or specifications, determination of structural integrity, or prediction of service‐life. On the other hand, development of new nondestructive test methods, improved sensitivity, or faster data acquisition and analysis may allow for nondestructive testing applications that hitherto did not seem feasible or economical. This article provides a brief overview of established methods and emerging applications in nondestructive testing of polymers and polymer–matrix composites.
