Özet

In this study, the effects of the warp knitting pattern and reinforcement alignment on the mechanical performance of

textile-reinforced mortars were experimentally investigated. Five polypropylene fabrics with distinct loop densities

(49.8–65.4 loops/cm2), porosities (38-51%), and pore sizes (0.96–1.45 mm) were produced and embedded into a

mortar matrix in both weft and warp directions. Mortar composites were evaluated through flexural strength,

compressive strength, and water absorption tests. The results demonstrated that both fabric construction and

reinforcement alignment affected textile-reinforced mortars behavior. When the textile reinforcement was placed in

the weft direction, the flexural strength increased significantly, rising from 12.26 MPa in the control to 15.96 MPa in

textile-reinforced mortars. Fabrics with compact structures exhibited improved crack propagation and enhanced

flexural performance. Compressive strength varies between approximately −7.4% and þ6.7% compared to the control

group, depending on the fabric type and loading configuration, exhibiting an orientation-sensitive interfacial transition

zone response.
