The idea of the direct curing in space environment came to
me about 18 years ago. At that time, I was not sure, if it was done or it is
impossible. All these years have been spent to get clear answer: yes, it is
possible, but no, it is not done.
I met these two comments as reaction on my presentations and
publications. People, who are far from space business, say, “it is done, and
even ISS is done by this way!” People, who work in space industry, say, “this
is impossible, but I do not know why?” All of these comments are not true.
During these years, I was carrying out a number of
investigations, including experiments and theoretical calculations. Part of the
results have been published and presented on conferences in different
auditoriums and countries.
First time, a general way of direct curing was discussed in
Russian journal “Plastic mass” (1997, No.8) and republished in English in
“International Polymer Science and Technology”: Kondyurin A.V., Building the
shells of large space stations by the polymerisation of epoxy composites in
open space, Int. Polymer Sci. and Technol., v.25, N4, 1998, p. 78-80.
After that the further results have been published in a
number of journals:

The recent experiment has been done on the curing in stratosphere.
First time, it was shown, that cosmic rays play role of additional hardener for
the polymer. Space makes polymer harder. This real flight experiment supported
previous laboratory investigations and made me sure, that it will work in real
space flight.
