Modeling the stress and resistance relaxation of conductive composites-coated fabric strain sensors

نویسندگان

چکیده

Electrical relaxation of flexible sensors using the conductive polymer composites as sensing materials has been constantly reported major obstacle for accurate measurement, yet still roughly characterized by mechanical rather than an effective underlying mechanism. In this work, fabric strain based on carbon-particle-filled and knitted substrate were studied. A serial model sensor was established according to its structure, then extended electromechanical introducing strain-resistance properties elements. Methods elaborated extracting mechanical, electrical status parameters model. Tests conducted 5 randomly-chosen samples. The firstly determined each sample proposed methods implemented predict resistance response during relaxations. Results show that relative mean error predicted only 0.2%, with averaged determination fit 0.9230. correlation between measured observed 0.9783 average. Conclusion can be drawn is characterize mechanism sensors.

Modeling and Predicting the Stress Relaxation of Composites with Short and Randomly Oriented Fibers

The addition of short fibers has been experimentally observed to slow the stress relaxation of viscoelastic polymers, producing a change in the relaxation time constant. Our recent study attributed this effect of fibers on stress relaxation behavior to the interfacial shear stress transfer at the fiber-matrix interface. This model explained the effect of fiber addition on stress relaxation with...

Modeling of Tensile Stress-strain Relation of Pseudo Strain Hardening Cementitious Composites

This study proposes a new comprehensive theoretical approach for predicting tensile stress-strain relation of Random Short Fiber Reinforced Cement Composites (RSFRCC) showing Pseudo Strain Hardening (PSH). This approach is grounded on solid basis of micromechanics, which describes PSH phenomenon in terms of constitutive properties of fiber, matrix, and fiber/matrix interface. The proposed model...
