THE EFFECT OF NUMBER OF WALLS WITH DIFFERENT THICKNESS ON THE PROPERTIES OF THE POLYCARBONATE PANELS

Abstract

Polycarbonate is a durable, strong, transparent new polymer material. It is used as building material or element because of its properties such as high strength, light transmittance, recycling, lightweight and vapor transmittance. Unlike most thermoplastics, polycarbonate undergo large plastic deformations cracking or breaking so it can be produced with different dimensions and shapes. Polycarbonate panels consist of different numbers of walls with different thickness. Generally, the properties of the polycarbonate panels are determined with all structures of the panels. However, the effect of the number of walls should be determined on the characteristic properties of the polycarbonate panels.  Especially transparency and thermal transmittance should be effected by the number of walls. In this study, characteristic properties of the polycarbonate panels such as light transmittance, water vapor transmission, impact and bending strengths, should be tested with different numbers of walls or thickness. Finally, the characteristic properties of the polycarbonate panels are suitable when the number of walls and thickness are low.
