Fiberglass seperation

Could be a number of things. The smaller the part, the less bonding
area there is to hold everything together and the easier it might be
for separation to occur. If the small parts and large parts are bonded
the same, the strength shouldn't change. Looks like the mechanical
application AFTER the bonding has occurred is causing the separtation,
not the bonding technique specifically. Using a wrong bandsaw blade
could also aggravate the problem, and using this technique might not be
the best route anyway. For flight structures, I always used a dremel
with a cutoff disc or saw blade to make the final cuts needed. Makes a
much cleaner cut than a bandsaw blade and no separation between the
foam and fiberglass. Hope this helps

Ok, I've made a few pieces to try out using 1/4" foam and fiberglass on
both sides. When I cut the pieces to shape with my band saw, small
strips (1/4" or so) seem to want to seperate. Is this common or did I
mix the epoxy wrong? The big parts are staying together, the fiberglass
itself is staying to gether but the small parts are seperating from the
foam.
