Reverse piezoelectric behavior of carbon fiber thermoplastic-matrix composite

Abstract:

The reverse piezoelectric effect was observed in the through-thickness direction of a continuous carbon fiber nylon-6 matrix composite. The piezoelectric coupling coefficient was 2.2 × 10-6 m/V, as determined up to an electric field of 261 V/m. The effect was largely reversible upon turning off the field and was unaffected by field reversal. It is attributed to the electric dipoles in the nylon-6 matrix.
