One company did just that a few year ago they made a range of carbon rods called the Hexograph they did not catch on . I found one on a salmon beat smashed to smithereens. When I asked the ghillie about it he said a client had lost two fish using it and had thrown it on the bank and jumped on it several times then threw it in the bushes this was in about 96.mg:
Bruce and walker, they still make 'em. At close on £900 a pop, for an avon rod, I'm not surprised they didn't catch on.
