Summary This paper presents a comparative study on different ways to determine the mechanical properties of glass fibre composite materials. This work underlines the accuracy of the results obtained with a dynamic characterisation method which is developed as part of non destructive evaluation by ultrasonic waves, compared to a static characterisation method by tensile tests.
