Acoustic and Vibration Responses of Lexan Plate Constructions

Lexan, a commercial form of polycarbonate resin thermoplastic, has some acoustic and vibration damping capabilities, among other properties, which have recommended it for building, vehicle and appliance constructions. However, along the lines of intelligently designed periodic-structure materials, with more recent understanding, these capabilities can be enhanced in different ways, but there has not been a systematic exploration of this process. Such could be useful in the consideration of possible meta-material applications of lexan constructions. This paper makes a report on work in which some construction patterns of lexan structures are tested. Deductions are made from the results in order to aid in the beneficial design of such structures for vibration and acoustic containment.
