Abstract

This paper investigates self-sensing properties of continuous carbon fiber reinforced, 3D-printed beams as function of the number of reinforced perimeters. Samples containing various numbers of reinforced perimeters are tested for their stiffness and strain-dependent resistance using three-point bending tests. The mechanical properties are modelled using classical beam theory and the resistance can be estimated using the resistance of the fiber additive. Large resistance changes are measured during bending, which results in a high responsivity.
