certification of composite aircraft

i am considering building a zenith-air stol 701 kit plane which is
usually made from riveted aluminum, but instead i would like to build
it primarily out of carbon fiber composites. how would such a
building strategy affect the airworthiness certification procedure?
can someone please describe or provide links to a concise summary of
the regular certification process of homebuilt aircraft especially
with regard to fees, what the builder and inspector do during the
process, how many inspections are done etc, thank you.
