Just wanted to share these picture on hollow glassfibres. Dont you thing the hollowness of these fibres could be an advntage in infusions. Acting like a flow media. A pitty they dont sell this stuff in UD format.
no, because the friction to get liquid into those fibers means it will have to be highly viscose…resin would not flow into the fibers.
And then you have less glass, and more resin anyway…
i dont want resin inside the fibres. but the tunnels would constantly degass the laminate
or carbon nano tubes?
what about? CNTs are in their own right, totally different and good.
What would be the advantages of hollow glass fibers? I suppose that in monolithic laminate parts it will somewhat stiffer for the same weight because of its lower density. But for sadwich structures really this not going to do any difference, right?
Lighter, stronger in compression, less thermal conductivity, less RF loss, etc.
Can’t use a core for all purposes. Sometimes you can’t use carbon, so this is a lighter and less dense.
If you use this with a sandwich structure…again, less weight, more compressive strength, etc etc etc
I’m not sure about that, actually my question is, if tensile strength and modulus decreased in same ratio that decrease glass density (biggest hole),because youare losing glass, who makes a mechanical force. If so, there would be many advantages, maybe in compresive as you say, but it would be heavier than standard glass, because you would have more resin for same glass, for same mechanical strength. Here a pics to better understand.
this is an extreme example

My guess may be correct?
Hmmmm interesting…Im guessing rather expensive?
