Abstract Porous Materials, such as sintered fiber felts (SFFs), can contribute to&#xD;the reduction of aircraft noise by acting as a low-noise trailing edge (TE). A rolling&#xD;process with a time-varying rolling gap was sucessfully used to tailor the aeroacoustic&#xD;properties of SFFs. To ensure the suitability of rolled porous materials for application,&#xD;the mechanical properties after rolling must be investigated. The objective of this&#xD;study was to clarify the effect of the rolling process on the damage evolution during&#xD;tensile loading. A SFF consisting of a functional layer and a support grid made&#xD;of alloy 1.4404 was used for rolling. Interrupted tensile tests in combination with&#xD;computed tomography (CT) were used to investigate the damage evolution of asreceived&#xD;material, uniformly rolled material and material rolled with a gradient in&#xD;thickness reduction. Metallographic examination and fracture surface analysis using&#xD;scanning electron microscopy (SEM) complemented the CT analysis. Uniformly rolled&#xD;material with a low degree of deformation (-0.74 ≤ φ < 0) failed identically to the&#xD;as-received material. The functional layer failed first, starting from the center. The&#xD;support grid subsequently failed due to the incremental failure of individual wires. The&#xD;material rolled with a gradient in thickness reduction failed accordingly. A significant&#xD;change in damage evolution occured for material rolled at high degrees of deformation&#xD;φ≤-1.53, where the support grid fails first and the functional layer second. The rolling&#xD;process using a time-varying rolling gap does not result in a detrimental mechanical&#xD;behavior under tensile load. The results improve the general understanding of the&#xD;effects of rolling processes on the properties of porous materials and allow the damage&#xD;behavior to be taken into account with regard to its application as a TE.
