What are modern Merlin rotor blades made from?

What are the rotor blades of a modern naval helicopter made from?

For the publicly documented 1997 EH101 blade he checks, the construction combines titanium, Nomex aramid honeycomb, glass fiber, carbon fiber, and epoxy resin.

Rather than guess about the latest blade specification, the answer uses a Science Museum catalogue entry for an EH101 tip section. A rotor blade is a composite structure rather than a single material: metals, honeycomb core, reinforcing fibers, and resin contribute different strength, stiffness, weight, and durability properties. The public museum specimen provides a firm historical construction example without implying access to a current military specification. A 1997 blade may not represent later upgrades.
