This paper investigates the tensile behavior of commingled polypropylene/glass yarns at different testing speed. A protocol to perform yarn tensile tests is defined and tests are carried out on yarns before and after weaving (yarns extracted from the fabric) in order to characterize the weaving damage. A protocol is also defined to perform tensile tests on 3D-fabrics. The tensile behavior of a 3D-fabric made of commingled yarns is investigated and results are compared with yarn tensile tests.
