As i see it:
Think of glass fiber: Resin and glass on their own are brittle, put them together and a tough laminate is created.
The spider emits the carbon tubes out through its spinners and so soaks them into the silk as the thread is created.

An expert will be along shortly. :)

I am worried carbon nanotubes may be the next asbestos... if they run through the spiders system and get crapped out the spinerets... where else are the accumulating?
