Abstract:

This Phase I project will investigate fabricating an insulating material with enhanced
thermal properties for improved thermal comfort of astronaut hands during extra-vehicular
activity (EVA) in space. The approach involves incorporating phase change materials
(PCMs) within a synthetic fiber matrix for later conversion into test fabric. At
the phase change temperature, PCMs absorb and hold a high quantity of heat during
the heating cycle which must be removed from the PCM before its temperature can begin
to change. Thus, a glove insert fashioned from this material could significantly
improve thermal comfort by preventing astronauts' hands from experiencing temperatures
too much above or below the perceived thermal comfort zone improving, thereby, EVA
performance. This material could also be applied to the manufacture of articles of
clothing without the development of new technology. Phase I would investigate the
technical feasibility for producing such a unique material and evaluate it in comparison
to a control fabric.

Potential Commercial Application:

Potential Commercial Applications:  Insulating materials with enhanced thermal properties
could be used in harsh
nvironments where improved thermal comfort is needed.
