Abstract:
Super-pressure balloons which enable long duration flights have been developed to
overcome the problem of high cost of artificial satellites. We have been studying super-pressure
balloons which have film structures covered with nets of high tensile ropes. The
strength of the net is important to sustain the super-pressure; however, a detailed experimental
investigation has not yet been carried out. The purpose of this study is to evaluate rope fracture
strength to verify its applicability for a super-pressure balloon and to verify the mechanism that
limits its strength. The net is a mesh of ropes and the rope is made of twisted two strands,
which consist of many thin fibers. To achieve this objective, tensile tests were carried out for a
single fiber and rope. The tensile strengths of a single fiber and rope were lower than that of
the bulk specimen; the strength of the rope was higher than the required strength. Next, tensile
test was carried out by changing the twist angle to study their relationship. A normal twist
angle was 18.3 degrees. The greater the difference in the normal twist angle, the lower the strength of
the rope. We assumed that there is a drop in the strength of the rope because a twisted rope has
a torque which produces a twist back force and cuts the fiber. Next, numerical simulation was
carried out to confirm this assumption. Three pitch lengths of rope models were loaded with
200 N of force. Results from the analysis shows that there is high stress between strands, and
the rope turned to twist back. Therefore, it was assumed that the rope has a torque and breaks
torsional balance, which cuts the fiber.
