IMPEDANCE-MATCHING COMPOSITE MATERIAL FOR AN ULTRASONIC PHASED ARRAY AND A METHOD OF MAKING |
摘要 |
<p>The present invention discloses an acoustic composite material for an ultrasonic phased array and a method for making. The acoustic composite material is formed from a microcapillary array having a plurality of holes of a constant cross-section and volume fraction. In each of the plurality of holes of the microcapillary array, a polymer fill is deposited therein. The polymer filled microcapillary array is cut at an axis perpendicular to the microcapillary array into a plurality of sections. Each of the plurality of sections are then ground into a predetermined thickness and bonded to a phased array of piezoelectric elements and backfill material.</p> |
