Abstract
This paper aims to search for alternative techniques for measuring the Young Modulus without the use of strain gauges or extensometers and to demonstrate how different parameters can influence its value, such as number of fiberglass layers, fabrication techniques and the method used for measurement. This property seems very simple, and for that reason may have its precise calculation neglected, but the smallest variation is the Modulus can have a huge impact on the estimation of the thickness for pipe repairs using composite sleeves. This paper presents not only different methodologies to calculate the Young Modulus, but also shows the impact these methods can have in system repairs and how they can lead to premature failures or to the overestimation of the repair thicknesses and its costs.
