Abstract In this article a mechanical characterization of filament wound pipes is investigated. The tested pipes are composed of E glass/vinylester with ±55° angle wedding. The mechanical behavior under axial monotonic loading is studied using acoustic emission. The test was carried out according to the instructions of standard ASTM-D 2105-01 test. The experiment determines the damage mode using two methods: acoustic emission and tensile test. The results of acoustic emission associated to those obtained from tensile test, are very promising and show the relevance of the developed nondestructive test to the prediction of the mechanical behavior of filament wound pipes.
