Abstract:

Scientific Research Balloons are used to carry instrument payloads into the upper
atmosphere.  Improved materials and designs are needed to enhance the reliability
and performance of these balloons.  This Phase I program seeks to examine an ordered
polymer film, PBT (poly-p-phenylene benzobisthiazole), for application as a balloon
film material.  PBT is an expremely strong, stable, and relatively inert polymer
with good UV resistance and toughness at cold temperatures.  The proposed program
will examine the mechanical properties of PBT relevant to this application and determine
film characteristics which could be improved.  Using baseline film mechanical test
date, this Phase I effort also includes initial steps tomodify the film for balloon
applications. 

If Phase I shows promise, Phase II will develop and expand film fabrication techniques,
further develop sealing methods and establish an appropriate design for a prototype
PBT balloon.
