Download or read book Fabrication of Piezoelectric Ceramic Polymer Composites by Injection Molding written by and published by . This book was released on 1993 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Piezoelectric ceramic/polymer composites have many applications in advanced Navy transducers and commercial ultrasonic imaging. Unfortunately, their application has been limited by the lack of a manufacturing-viable technology capable of meeting both the low cost and high volume production requirements. The principal manufacturing difficulty lies in the handling of millions of fine PZT fibers during their assembly into a typical composite transducer installation. In this program, Materials Systems Inc. (MSI) has demonstrated that ceramic injection molding is capable of meeting the stringent transducer cost and assembly needs of piezoelectric ceramic/polymer composites for Navy applications. The injection molding approach overcomes the difficulty of assembling oriented ceramic fibers into composite transducers by net-shape performing ceramic fiber arrays. Aside from this advantage, the process makes feasible the construction of composite transducers having more complex ceramic element geometries than those previously envisioned, leading to greater design flexibility for improved acoustic impedance matching, lateral mode cancellation and superior actuator performance.

Book excerpt: Piezoelectric Ceramics focuses on the relationship between piezoelectricity and ferroelectricity as they apply to ceramics, taking into consideration the properties of materials that are being used and possibly be used in the industries. Composed of 12 chapters, the book starts by tracing the history of piezoelectricity and how this affects ceramics. The different measurement techniques are discussed, including dielectric, ferroelectric, and piezoelectric measurements. The book proceeds by discussing Perovskite structure and barium titanate. Covered areas include electric field, piezoelectric properties, particle size effect, and dielectric strength. The properties, compositions, and reactions of various perovskites are discussed. Numerical analyses are presented in this regard. The book also offers interpretations of the experiments conducted. The discussions end with the processes involved in the manufacture and applications of piezoelectric ceramics. Concerns in manufacturing include calcination, grinding, mixing, electroding, firing, and quality control. Piezolectric ceramics are applied in air transducers, instrument transducers, delay line transducers, underwater sound ultrasonic power, and wave filters. The book is important for readers interested in doing research on ceramics.

Download or read book Ultrasonic Polymer Composite Transducers for Use in Biomedical Applications written by Herman Inaki Schlaberg and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for improved acoustic sensing in adverse applications such as medical and underwater imaging has led to the research of acoustic sensor materials other than the traditional ceramic materials such as PZT and LiNiO3. Polymer composite materials offer a potential solution to this need by aiming to combine the desirable properties of ceramics, such as high transmission coefficient and high electro-mechanical coupling, with the preferable features of polymers, such as close acoustic matching to biological tissue and wide bandwidth. The present work investigates two polymer composite materials that seek to integrate the desirable qualities of ceramic and polymer materials. The first of the materials investigated, PIEZEL, is a composite material in which the ceramic PZT is embedded in a matrix formed by the polymer PVDF. The components of the other composite, PIEZOFLEX 1, are PZT and a proprietary epoxy. In order to assess the dynamic response of these composite materials, the electric, piezoelectric and elastic properties of the materials have been determined. The mechanical integrity of the materials have been evaluated using Dynamic Mechanical Thermal Analysis (DMTA) techniques and figures for frequency and temperature dependence of the elastic modulus and mechanical loss factor are presented. The electronic circuitry employed in ultrasonic systems is rarely described in the literature making the reproduction of experiments difficult. Detailed description of the development of the circuits necessary to make the transducers operative is given here. In order to evaluate the behaviour of the materials under varying transducer configurations, several linear transducer arrays with up to 32 elements have been designed and developed employing different architectures such as corona poled arrays, slotted arrays and monolithic PCB arrays. Results obtained with these transducers, in the form of back-scattered images from simple target objects, prove that these composite materials hold the potential to be successfully employed in more complex imaging applications.

Book excerpt: The objective of this program was to manufacture a large area 1-3 piezoelectric composite transducer array for test and evaluation using the Materials Systems Inc. ceramics injection molding technology.

Download or read book Near Net shape Fabrication of Ultrafine Scale Piezoelectric Ceramic Polymer Composites written by and published by . This book was released on 1997 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this program, new net-shape forming technologies were developed for producing fine scale 1-3 and 2-2 piezoelectric ceramic/polymer composites. Piezocomposite materials having extremely fine piezoceramic elements were fabricated using a modified ceramic injection molding process similar to that developed by MSI 1 for coarse scale piezocomposite manufacturing. The principal technical challenges were to make extremely fine PZT ceramic 1-3 and 2-2 preforms without defects or distortion, and use these to and produce piezocomposite samples having sufficient thickness to achieve lateral mode-free response. PZT rods and strips having width dimensions in the order of 25 to 60 micrometers and length-to-width aspect ratios in excess of ten were demonstrated on a research scale. These were used for experimental demonstration of high frequency acoustic imaging arrays for medical ultrasound and Navy mine hunting applications. The new piezocomposite fabrication technology is finding applications ranging from diver-held sonar to low frequency mine detection and classification to advanced net-shape piezoelectric actuators. The program has influenced development of net-shape formed accelerometers for active surface control, as well as coarse receive arrays for submarine use. Under separate SBIR funding (ONR Contract number N00014-95-C-0117), the fine scale molding technology has been scaled up to the point where large (150 x 50 mm) pieces having pitch dimensions below 200 micrometers can be produced every few minutes. Prior to this work, the only net-shape forming approach available for producing piezocomposite was one developed by Siemens 2 which utilized ceramic slip casting into fugitive molds produced by x-ray photolithography.
