Abstract (EN): Reinforced thermoplastic and thermosetting matrix pipes, produced by filament winding or centrifugal casting, may be subjected to different types of loading conditions as well as different environmental conditions. However, they may suffer damage due to unexpected working conditions (low velocity impact, such as stones, tools, etc). This paper describes a methodology based upon fracture mechanics to evaluate possible pipe damages. It reports a set of tests made to characterize materials and pipes. Fracture Mechanics tests were made in filament wound flat samples and tubular specimens were also subjected to low velocity impact tests. The study of damage evolution was done by using the ESPI (Electronic Speckle Pattern Interferometry) technique in order to determine the delamination area.
