A novel carbon fiber (CF) strain sensor is developed providing the unique feature of a fracture-based, resistive measuring principle enabling a spatially resolved strain measurement. So far the sensing function is applicable to the measurement of positive strain (elongation), but not for negative strain (compression) since the filament fractures are closed in unloaded condition. In this work, a 3-step sensor manufacturing process is established making use of plastic deformations of partially cured epoxy networks in order to overcome this current limit. After performing the procedure the filament fractures are open in the unloaded condition and pushed together during compression enabling the measurement of negative strain. An elongation-compression ratio of 0.3 was identified in a cantilever arm configuration. The results show that the measuring range of the sensor can be shifted towards the compression domain by means of the advanced sensor manufacturing process making use of plastic deformations in partially cured epoxy networks.
