Electrical sensing properties of carbon fiber reinforced plastic strips for detecting low-level strains

In this work, the electrical sensing properties of carbon fiber reinforced plastic (CFRP) strips under tension strains were studied. The electrical resistance change ratio of a CFRP strip responds to the applied axial and transverse strain. Under 500 microstrain, the strain sensing properties of CFRP strips with different width–length (w/l) ratios vary significantly. The experimental results showed that the nonlinear transverse effect was...
