leading prepreg companies for aircraft interiors?
i am trying to understand who the leading pre-impregnated fiber companies for composite aircraft interiors are.  who would you consider the leader in:
-  quality?
-  service?
-  technology/innovation?
the candidates include companies such as hexcel, cytec, toray composites, jd lincoln, stesalit, fibercote, newport, yla, lewcott, acg, aerocell, and others.  please provide feedback per your opinion.  thanks.  
check out our whitepaper library.
not quite sure, but ...
if you're after basic material, mc gill aren't bad,
if you're after finished designs c&d aerospace are reasonably well known.
ps, i'm not associated with either company.
