Tips for Fiberglass Cryogenic Tank Design

Wow. I used to work a great deal with custom fabricated fiberglass reinforced storage tanks (almost every day), and I've never heard of anyone using them down in that temperature range. ASME RTP-1 and I'm guessing ASME Boiler and Pressure Vessel Code Section X might be reasonable references for starters, but I would bet that this temperature is way beyond the scope of these documents, and last I used them, they were not strong references for horizontal tanks. If I were designing, I would be very concerned with adjusting for laminate strength and stiffness at this temperature (whatever that might be - I haven't the slightest idea whether the strength and stiffness are comparable to room temperature properties). I would also be very concerned about thermal expansion (or contraction, in this case) and the way in which the tank is allowed to shrink on its supports as it comes down to temp.
