The electromechanical properties of a segmented polyurethane elastomer were investigated as functions of temperature and frequency. Two transitional phenomena were observed in the temperature range from -50 to 85°C. In these transition regions, the

A composite aluminum/PZT shear transducer has been tested as a sensor during prototype development. The mechanically amplified flexi-distortional system may improve the dhgh figure of merit by transferring the compressional stress on the device to a

We show that the large electrical-field-induced strain response observed in certain polyurethane elastomers is a thin-film effect. Based on the frequency dispersion of the strain response in samples with different thicknesses and the thermally stimul

A new polyurethane formulation has been developed for use as the acoustical window for a soft sonar dome. The polyurethane is based on a 3000 molecular weight difunctional polybutyleneoxyglycol (PBOG) softblock. In addition, a moderately high trifunc

Successful operation of high‐frequency sonar arrays requires an acoustic window that not only has a minimal interference with the acoustical signal but also is sufficiently rigid to protect the electronics from arctic ice penetration. Current desig

Copolymers of vinylidene fluoride and trifluroethylene are presently being considered for many piezoelectric applications. In contrast to the poly(vinylidene fluoride) homopolymer, a transition from the room temperature ferroelectric phase to a parae

Thermomechanical analysis was carried out for various phthalocyanine resins. The polymer based on the C-10 diamide resin was then chosen for evaluation as a potential composite matrix material. Prepregs with Thornel 300 graphite reinforcements were s

A fracture mechanics approach was applied to determine the adhesive fracture energy of various high performance polymers. These polymers, including both thermosetting and thermoplastic materials, generally offer higher temperature capability than con
