Conductive Geotextile and Method of Manufacturing the Same
Problem Statement

Traditional geotextiles face challenges in electrical conductivity and mechanical durability, particularly under harsh environmental conditions. Existing conductive geotextiles either lack uniform conductivity or are prone to physical degradation, limiting their effectiveness and lifespan in critical applications such as soil stabilization, filtration, and electrokinetic consolidation.

Abstract

This invention introduces a conductive geotextile designed for enhanced electrical conductivity and mechanical stability. The geotextile is made from woven fabric consisting of conductive composite yarns, which integrate conductive metal wires and non-conductive polymer filaments. This innovative structure offers uniform electrical conductivity across the geotextile, significantly enhancing its functionality in geotechnical applications.

Uniqueness of the Solution
  • Composite Conductive Yarns: The geotextile features composite yarns that intertwine conductive metal wires with non-conductive polymer filaments, ensuring consistent conductivity and mechanical strength. 
  • Uniform Conductivity: Engineered to provide homogeneous electrical conductivity throughout the fabric, enhancing its effectiveness in electrokinetic applications. 
  • Enhanced Durability: The woven structure offers high tensile strength and resistance to environmental wear, making it suitable for demanding geotechnical applications. 
  • Simplified Manufacturing Process: Utilizes readily available materials and straightforward manufacturing techniques, reducing production costs and complexity.
Prototype Details

The prototype is constructed using a loom to weave conductive composite yarns into a robust fabric. The yarns are crafted by tightly twisting conductive metal wires with polymer filaments, ensuring the wires are predominantly located at the core to enhance conductivity and protect against corrosion.

Current Status of Technology

The conductive geotextile has been fully developed, with successful prototype testing that demonstrates its functionality and benefits. It is ready for commercialization and can be scaled up for widespread use in various industries.
