The Sensing Characteristics Responded by Resistance of Carbon Fiber Layer with Epoxy-Matrix

Article Preview

Abstract:

Carbon fiber composed with epoxy-matrix is revealed to be a kind of functional composite material, which has sound sensing characteristics. The sensing ability of mechanic-electric character and temperature-electric character of carbon fiber layer based on the epoxy matrix was experimentally discussed in this paper. Through the uniaxial tension the CF layer reveals a good performance by resistance changing with response to the loading. In temperature-resistance testing, CF layer also has a good response to the temperature changing by its resistance varying. Carbon fiber composed with polymer will provides a new kind of sensor which can be used as force sensor and temperature sensor as well.
