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.

Keywords
