Abstract
This project develops smart textile reinforcement (STR) systems with integrated fiber-optic sensors and multi-modal environmental monitoring for lifetime assessment of concrete structures. The STR system combines multifunctional textile reinforcements featuring load-adaptive fiber paths – enabled by highly flexible yarn deposition systems – with advanced sensing technology to provide real-time structural health monitoring and a dual function as both structural reinforcement and distributed sensing platform. Integrated nanomaterial-based sensors monitor critical degradation parameters including moisture content, chloride ingress, and pH variations, while distributed fiber-optic sensors provide high-resolution, two-dimensional strain fields. The system fuses locally resolved strain measurements together with environmental data for predictive maintenance and automated structural assessment. Validated through lab-scale testing under defined loading and environmental conditions, the STR system will enable continuous monitoring of both new and existing concrete infrastructure. This integrated approach directly contributes to CARE's objectives in sustainable material design, structural adaptability with smart functionalities, and digital automation for predictive lifetime management of concrete structures enabling more resilient and sustainable infrastructure.
