Was substrate delamination looked at?  It is a very real problem in just about
all current composites were under cyclic and impact loads the various layers
of the composite will delaminate and for a pressure vessel that would spell
real problems.
I agree with you on the use of compsites as 'magic bullets'.  
	One really good source of information in a few years will be the aerospace
industry, with the dramatic increase in the use of composites watch out for a
few spectacular failures over the next few years (maybe 10 to 15) as they find
out the limits of the material simliar to all the aluminum fatigue failures
they had a few years back.
