The technology to create a composite a single strand of glass-carbon fibre is still in its infancy and I am surprised that anyone is using this to make speaker cones. I was under the impression that the technology for hybrid fibers using glass and carbon still has not been productionised.
However given the age of my knowledge I would take all I have said above with a pinch of salt. Things do change quite fast even in material science.
BTW I know this because this technology would find great use in sailboats as well as a bicycle frames (2 other things I was interested in). Areas where stress and tensile strength is of great importance.
One option could be using a mix carbon and glass shards in epoxy. However I dont think of this material as very strong or stiff. There is no cross weave. A regular fiberglass, kevlar, or carbon fiber cone would be better.
polyproplene is much overrated. doped paper is a lot nicer, provided the doping is done well. Other options are various metals and proprietry blends such as Aerogel (Audax).
