composite helicoptor rotor blades
(OP)
I am trying to find information on past and present manufacturing methods of helicopter main rotor blades. If anyone can help by giving me some information, or point me in the right direction on some books or papers that i can find, it would be greatly apprecciated.

helicopter main rotor blade was made from metal (aluminium) as far as i know, because of this the earlier rotor blade need hinge to overcome the coriolious effect. His manufacturing should be similar to other normal metal wing -> bending.
The modern main rotor is made from composite as skin and nomex/honeycomb or hard foam as core, also called sandwich. Because of the flexibility it then doesn't need hinge again, so it is called hingeless main rotor. The manufacturing is the like other composite part :
prepregs -> lay up over the die -> curing
Hope it would help you!

They may help!
As a Helicopter producer, they have been building Carbon Fibre skinned rotor blades for years!
And the EH101 helicopter in all it's variants (Cormorant/Merlin etc) have these blades.

They tend to be quite proud of their blades, and an approach to their publicity department might well pay off.
