Tensile strength of 3D textiles reinforced cementitious composites plates

Abstract

Tensile plate specimens with dimension of 450×100×40mm were cast with 3D glass fabric having three different thicknesses 6, 10 and 15mm to measure their tensile strength. Plates with one and two layers of chicken wires, as well as micro steel fiber of 0.75% volume fraction were tested under tensile for comparison with references plates. Cement mortar with 61.2MPa cube compressive strength at 28 days was designed for casing the plates. The results indicated that after cracking of the mortar the textile reinforcement adds a strain hardening trajectory, that cause failure to occurs at slightly higher load and a higher strain. The improvement in tensile strength at 28 days ranged between 5 to 30%, and for 90 days between 5 to 60% for the three types of fibres used. Based on the results a significant increase was indicated with micro steel fiber.

Flexural Behavior of Concrete Members Reinforced With 3D-Textile Fibers-A Review

“…By comparing the difference in thickness, the tensile strength for sample with 10 mm thickness was greater by 165 % than that of 6 mm, as well as the samples with 15 mm textile thickness was greater by 100 % than that of 6 mm. On the other hand, when comparing the difference in the number of textile-fiber-layers, the usage of two-layers was greater than one-layer by (105 and 4) % for (6 and 10) mm thickness, respectively [13].…”
