First time we've seen a student here try and get us to do their work for them


Survey is OK but then it's suddenly us writing the essay for them....
Anyway back to ECO CRAP.
Right - sorry folks but eco resins have reduced mechanical properties and longevity. Very hard to find info as the google results are infested with greenies and companies that say "eco epoxy resins are strong" which is a beautiful motherhood statement but - strong compared to what? Stronger than wood glue, yes. Not as strong as traditional epoxy resins. Maybe stronger than old surfing styrene-based resins.
The lies talk abotu them being biodegradeable which is false - cured epoxy is inert and will not break down... they are talking about the components prior to curing. Lies in advertising.
But lets say they're OK resins if used right, and they're just as strong.... but the product strength is in
fibres and that is what is far more relevant given our sport.
So to fibre - basalt is tops like Gestie says, as it has a higher tensile strength than glass and is a bit stiffer, so it sits between S-glass (which is already 30% stronger then normal glass) and carbon. So its great. However - glass is made by melting sand, basalt is made by melting ... well, you guessed it, basalt rock. How novel. Same idea, different rock. So that is not more enviro friendly its just melting a different rock. There is more variation in basalt, and stuff from Kazakstan or Siberia or some sh!t was better or worse than some Pacific Is. stuff, I can't recall but that brings me to the next point:
Variability. Plants have variation, and flax or hemp will never be woven into a 100% homogenous product like man-made fibres.
Wood has variation too. Its nice as its unidirectional..... and with appropriate vac bagging, resin is drawn through the soft parts and not the hard so it becomes a little better. But nothing will fix the "slightly weak gaps" in drawn-out plant fibres.... we rely on the tensile strength of them and the soft parts are interspersed along the fibre at varying intervals
