Abstract
In the present work, mortar beams reinforced with polymeric reinforcing elements are manufactured using Polylactic acid (PLA), inspired by crack propagation deflecting architectures found in nature such as Sinusoidal and Bouligand architectures. Mechanical flexural properties of mortar beams are studied and compared with that of reinforcing elements with an architecture parallel to the direction of tensile stress as well as non-reinforced mortar beams. Furthermore, the reinforcement configuration and ratio are designed using principles from mechanics of materials. A Digital Image Correlation (DIC) technique is used to obtain the load-deflection curves during flexural evaluation. Results show that changing the microarchitecture of the reinforcement can enhance the flexural performance of the beam. Additionally, interface properties between the mortar and the reinforcing element are studied using pull-out tests. Interface properties were enhanced by introducing architectural patterns on the surface of the reinforcement. Finally, using material properties of the mortar, reinforcement and the interface obtained from experiments, a numerical model is developed and calibrated. The outcome of this study helps explore the opportunities of using novel nature-inspired reinforcement to enhance the mechanical properties of cementitious composites.
