ATK company mission: "Take over the world" They have always been big into
filament wound rocket motors casings. They just do not make propellant,
they design and manufacture the entire rocket motor. Senator Byrd secured
ATK a huge composite facility in poor old W Virginia paid for by you and
me so there is something to work on in WV. Now ATK has a huge robotic tape
laying facility in WV paid for by the government (Pork Barrelness at work)
and they compete with othe comapnies that had to buy equipment on their
own nickel.
This is a private opinion, not the company I work for.

Hi Bill,
ATK has a plant about 10-12 miles from were I live. They received a
contract for composite components on the Delta II,III,IV through 2008.
here is a web link to ATK:http://www.atk.com/homepage

Curiosity: Morton Thiokol supplies not just the rocket propellant,
(which, we were told many years ago was a derivative of liquid rubber) but
they also supply the rocket casings? Interesting.

Morton Thiokol does not make resin, BUT you are on to
something......Morton Thiokol, now called ATK ,filament winds rocket motor
casings, and that Shell 8500 is a favorite of filament winder guys.
Epoxies typically have extremely long shelf lifes. Some preformulated
epoxies do have consituents that may increase the viscosity with age, if
not refridgerated. As far as cost goes it is all relative. There are
expensive epoxies at about $15 lb. Regular epoxy (bisphenol A) is $3 lb
when purchased in a 55 gallon drum and about twice that by the gallon.
High temperature resistance usually comes from th echoice of hardener not
the epoxy resin. Epoxy resins that can increase temperature
(multifunctional) resistance are solids at room temperature-not too
pattern guy user friendly. Preformulated epoxy systems cost 5X-10X the raw
material-usually from the hardener side. Example-West systems epoxy is a
"formulated" hardener , ! that is a blend of several components and the
epoxy side is packaged straight from the drum.
