The main question was for strength related application of Nanotubes which appear to work exceptionally well not only improving strength to weight ratio but also improving the repairability of broken carbon fibre hulls, I added the Biocyl bit just for interest.
Apparently new processes have made Carbon Nanotubes cheaper to produce in bulk. So I thought it may interest the Cat section, being all about strong and light. The fact that they are starting to build offshore power boats from this stuff points to a great future as costs get lower and lower.
While I am no expert on Nanotubes I’m hoping that this may start a discussion that enlightens any one that has even the smallest interest in building with this system as I think it would be the ultimate building system. I’m also hoping that some more enlightened posters will join the conversation as to the best layup of fibres to go with the system, whether Pre-Preg, or infusion would be better.
From my enquiries
In terms of benefit of CNT combined with Epoxy resin (I suppose that you are using a blend bisphenol-A with Bisphenol-F for the infusion process) in hull
construction they will be beneficial in terms of de-lamination resistance (level of improvement expected 20-50% depending on the type of fiber used, lower level if it is glass fiber and higher level if it is aramid fibers), impact resistance, reduction of the Coefficient of Thermal Expansion (CTE) which means lower surface defect given by the difference in elongation between the fiber and matrix (epoxy in this case) and achievement of anti-static properties of the final composite material.
Having said all that perhaps I should have started this thread in the construction forum…..Perhaps the moderators would like to move it?
