if you are looking for information about automation in composite manufacturing please look what Janicki Industries is doing for Boeing. unfortunately there is not much information available as both Boeing and Airbus are very resistant to even tell which companies are developing technologies for them.
even people designing the aircraft have limited access to information. we are provided with few-hundred-pages documents describing how to design the layups, where to place fasteners, what sizes of plies to use, etc. but there is no single word about manufacturing process. all we can get is "people in manufacturing wants us...".
benefits from using composites in aviation are starting to be visible on assembly level but most of them is expected to come from reduced maintenance costs. switching from metal to composite does not only means replacing one material with another but changes whole philosophy behind the design. composite component alone can act as structural member, acoustic and thermal insulation and be a part of heat exchange or electrical systems (and that's not all it can do). shortly - that mean less parts and better integrated structure (according to Being metallic fuselage section was being made from 1500 panels, composite section allows 80% reduction).
better integration equals stronger structure so you can use higher pressure inside (equivalent of lower altitude) and that improves comfort.
less parts equals shorter assembly time as well as smaller drag penalty due less steps and gaps. decreasing number of parts reduces number of localization to check during overhaul, also.
as far as maintenance is concerned composite have one advantage over metallic parts and its name is corrosion. again, if we can trust Boeing, because of that service time between major overhauls can be doubled and that, in case of plane like "Dreamliner", translates into more than 100 flights.
I am not sure if Boeing is actually the leader in, lets say "high scale", composite technology. they've decide to take big step with B787, maybe even to big (if you look for amount of problems they had, and still have to, overcame). personally I prefer Airbus's approach - gradually, step by step (with growing knowledge and confidence), increase of using composites in their designs.
