Experimental and Numerical Investigation on the Flexural Behaviour of Hybrid Textile Reinforced Concrete Panels with Aramid and Ar-Glass Fibre Meshes
摘要
Textile Reinforced Concrete (TRC) strengthens cementitious materials by embedding textile meshes, offering improved structural performance. This work investigates hybrid TRC panels made with alternating layers of Alkali-Resistant (AR) Glass and Aramid fibre meshes placed within a Taguchi-optimised matrix. Various mesh arrangements and quantities were examined to study their influence on flexural behaviour, and the results were compared with TRC with identical mesh layers and conventional specimens. Numerical simulations were carried out in ABAQUS to support the experimental observations. A total of 37 TRC panels with dimensions [length × width × thickness, 1000 × 210 × 55 mm] were cast and tested under four-point flexural loading. Among the tested configurations, the panel containing four alternating layers of AR-Glass and Aramid mesh (4L4) showed the highest bending stress of 45.32 MPa, indicating enhanced load resistance and improved deformation capacity due to the combined contribution of both fibre types. The comparison between tests and simulations showed good agreement, with a linear correlation coefficient of R² = 0.917.
