Syntex
1/2 x weight, 2 x strength, …
I miss some other important factors to know what it’s worth:
? x cost
? x stiffness
I am unfamiliar with this product. Care to explain? It may, or may not, be similar.
The most difficult fabrics to cut for me are, Dyneema/Spectra.
So that’s my guess
Dynel cuts easy. So its not that.
I’ll add a guess too. It’s not 1/2 weight and 2x strength but about 70% weight and 132% compression strength of E-glass and is not as transparant as E-glass, but it’s glass after all:
H-glass (hollow glass fibres) http://www.ezentrumbilder.de/rg/pdf/td_en_hollow_glass.pdf
This is used in Witchcraft sailboards for it’s “cheap” compression strength.
Good guess, but it is NOT a glass based product. It is in the general catagory of ‘‘plastics.’’ It is a synthetic product. The 1/2 weight, and 2x the strength comment, is a direct quote from the distributor. Not something I made up.
Another guess, could it be non-carbonised carbon fibre?
Aka. Acrylic fibres (they are crystal clear)
Aka. polyacrylonitrile (PAN)
Kevlar is near 1/2 weight and more than 2x stronger than glass, in tensil. Plastic fibers like kevlar and dyneema have some stiffness, low stiffness is a common problem of “classic” plastic fibers like olefin (PP), pet fiber so they give tough but “chewing gum” skin when use with appropriate resin (ie with sufficient elongation to break). But kevlar, dyneema and vectran have bad adhesion with resin, sensibility to humidity and/or UV, some high mechanical caracteristics and poor ones too at same time. Finally there is not magic reinforcement, and reinforcement is nothing without appropriate resin…
That’s exactly why I asked for the
“? x stiffness”
factor.
Is it glassed with your ego tharikill? Rock hard and impenetrable…
remember the roundabout you played on as a kid
well its still there and it still goes round & round &round
cheers huie
Aloha Hans,
PM has been sent.
ah, the spinny thing.
PA or PP it was, I think, recalling the finer points of its appearance and feel.
Sadly at that age I didn’t know how to tell for sure…
Was it the oil price, the end of disco, or kindergarten that ended the spins?
Years later it was seen lurking in a basement, color leached out somewhat, hmmm, looked more like PA then I would guess but …
This is all a good read
But I’m waiting for the “Ding-ding” WINNER!
Rest assured, it is not Marsh.
Bill, that was cheeky of me…but you can’t start a thread like ‘I know the best material in the world…but I’m not telling’
Like ‘I have the best fin in the world … but I’m not showing’ ??
Just keep it to yourself then…rather than bait everyone…
.
I’m really curious what is this all about…
I work with dyneema and aramid to get impact resistence…
dyneema is so far the best material available…

some guys are now getting very good results with innegra, but only cloth I’ve seen so far is very open weave, I prefer the opposite…
