Integration of sensors or any other diagnostic technology directly into a material or structure
is a way to increase the safety level of the construction and provide other features as online
diagnostics, predictive maintenance or a functionality of early warning in case of component
failure. Many of the available embedded sensor technologies suffer from limited lifetime or
necessity to have a battery power or influence the structure integrity. Technologies with lower
impact on the structure, as integration of Fiber Bragg Grattings sensors, require expensive
sensitive equipment to evaluate signals. Application of sensitive coatings on the textiles for
reinforcement purpose is a novel and innovative approach. Using textile for the reinforcement
of concrete and composites allows subtile and still high-performance structures to be built.
The textile itself can be used as substrate for layers providing sensing functionality to measure
moisture, strain, load or to detect cracks in the material. The main advantage is the direct
contact of these additional layers with the measured material, in situ measurement, as well as
protection of the sensitive textile against ambient environmental conditions.
This paper will introduce flax textile reinforcement as sustainable alternative to synthetic
reinforcement material, coated with carbon-filled epoxy resin. The carbon provides conductivity
properties to the textile. Graphite and bio-carbon will be studied in this work. A detailed study
of textile conductivity properties with respect to the carbon concentration in epoxy will be
presented in the full paper. The promising results obtained with textile coated by epoxy filled
with graphite shows suitable conductivity levels for embedded strain/load measurement in
civil engineering. The results of epoxy-graphite and epoxy bio-carbon mixtures will be shown
together with the coated textile conductivity study. The potential for applications in moisture
detection in timber constructions such as CLT or GLT will be discussed in the full paper as well.
