Re: New rod material?
"Rice University researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists. The technique has implications for application of graphene materials in microelectronics that scale well below the limitations of silicon determined by Moore's Law."
This graphene - hexagonal boron nitride nano-technological development appears directed towards the limitations of silicone as a semiconductor wafer alternative rather than a re-enforceable fiber technology. A more probable next step for fly rod fiber is a refinement of the current 3M nano silica technology in which the silica particles are made smaller (sub-nano?) and more precisely and uniformly distributed within the composit matrix. Besides further increasing bonding strength this would facilitate additional compression of fiber bundling making rod blanks slenderer yet stronger than what we have seen thus far. How will they write their names on such thin walled small diameter blanks? Maybe with graphene etched lithography!
