Evaluation of the Production-Grade Class IV Flextensional Transducer Shell

Abstract

This report evaluates physical characteristics and mechanical properties of the production-grade composite Class IV flextensional transducer shell produced by Brunswick Defense. The void content was very low; the average was <0.5%. The fiber distribution was very uniform throughout the shell; the average fiber volume was 52%. Interlaminar shear strength averaged 11.4 ksi. The shear modulus was very nonlinear. Its initial value was 0.52 Mpsi. Through-the- thickness strength averaged 6.7 ksi in tension and 24.4 ksi in compression. Through-the-thickness test results revealed a nonlinear modulus in compression and a fairly linear modulus in tension.
