Evaluation of elastic modulus of carbon fiber reinforced polymers using an optical extensometer

Abstract

The paper presents the results of application of different techniques for processing of digital image correlation data. The algorithms are described and applied for determination of elasticity modulus of carbon fiber reinforced polymer specimens tested by uniaxial tension. Two ways of evaluation of elongation along with two methods of elastic modulus calculation resulted in four techniques which have shown quite similar results with a scatter of 0.5-2%.
