Abstract:
O-ring and gasket materials for space applications must meet
ordinary requirements for strength and resiliency, but must also
withstand radiation and low temperatures in space, atomic oxygen
in low earth orbit, and high temperatures on launch. Polyimides,
which are widely used for space structural applications because of
their ability to withstand severe conditions, are generally rigid
materials that do not provide the resiliency needed for o-rings
and gaskets. Fluorine-containing segments in polyimides are known
to reduce glass transition temperatures (Tg) without impairing the
stability properties. Under this project, polyimides with novel,
fluorinated segments will be synthesized.
Potential Commercial Application:
Potential Commercial Applications: The products are potentially
useful for a variety of o-ring and gasket applications where
chemical and thermal stability are needed in addition to low-
temperature resiliency.
