« on: March 29, 2024, 09:12:26 PM »

Alula is light and strong, but not particularly durable. I've seen a few Allula wings that appear to be delaminating. I don't know if that's the right word for what is going on, but it doesn't look good. The newer fabrics have a lot of promise but designers don't seem to be able to get the best out of them yet. I bought a new 4.5 F-One V3 when my V2 F-one disappeared. The new wing has some nice design features and lots of high-tech fabrics. But the center of effort is far forward that the wing can barely be depowered. I might push through and learn to use it, but I found my V2 4.5 and I'm back to using that so it isn't getting much of a chance.

The gold material that is on the Allula wings has nothing to do with Allula itself. It is a " look at me coating"  to make the clear Allula material stand out.
I have had 2 allula wings now that I've had close to and over 100 days of hard use and while the Canopy bagged out, the air frame itself stayed about 80% as stuff and new. the 5m did have some flaking.
In comparison , at 40 days on my Unit, it was bagged and airframe was fffflimsy.

 You gotta do a video on thos GG process(please)
I just dont see how foaming girilla glue can do the job or epoxy

The Gorilla glue sections eventually yellow.  That top shot was after primary cure.

Here are some shots that show the difference between the Epoxy and Gorilla glue laminations.  The XPS foam was uniformly Grey.  The yellowed areas were laminated with Gorilla glue. 

Whereas the sidewall 3.7oz S-Glass was Epoxy as was the top of the nose with 1.4 oz Fiberglass and Epoxy.

Yes!  Beasho was using Gorilla Glue to laminate fibers.

The dream was that Gorilla glue would be more accessible, and faster given its 1 part nature.  AKA no more mixing epoxy for perfect cure . . . .

My first board I used Gorilla Glue to laminate the majority of the nose and tail.  On this board I used it on the tail.

The good news is that it worked.  The downside was that it tends to set up too quickly, making it a bit hard to work with large patches of fiber lamination.

The other benefit is with Ding Repair.  You can just slop on some gorilla glue, cover with Tape and go surf 1 hour later.  No worry about making it water proof because the whole board is porous anyways.

Can someone throw up some picks or a video on doing a GG lamination please? the GG I'm thinking of is the brown, expandable glue but maybe that's not it?
it's keeping me up at night-someone please sort me out!

Both Gorilla Glue and Epoxy have a specific gravity of 1.1 meaning 10% heavier than water.  So, if there is any water seeping into the fiber it weighs LESS than the Glue would otherwise weigh permanently bonded into the fiber. 

Said another weigh, porous fiber will always be lighter than glue filled fiber whether or not it takes on water.

Well this is an interesting point.

So a board's skin/laminate soaking up water is lighter than a board's skin that is fully wetted out with gg or resin?

I don't get it, is Beacho using gorilla glue(GG) to laminate fibers? Further to the point,  how in the world is GG specific gravity compared  to water  in fibers relateable to anything?
I'm just diving into an 8ft xps DW board, no fill coat -raw dog peal ply finish board and don't want to miss any pertinant...stuff.

Hey there,

I was surfing with someone recently and asked this person if he finally joined the zone. He said he is having issues and nobody replied on his request. Does anyone know who I should contact for helping resolve this?

thanks!

I think the point was that kevlar absorbs water but innegra does not.
Innegra has excellent impact resistance  and is probably the lightest fiber out there.

If i was going to use minimal amounts of resin (or GGlue as i think Beasho is using) i would definitely go for a waterproof material.
Water is very dense and even a little amount seeping into the Kevlar fibers during the sesh will add weight.

Both Gorilla Glue and Epoxy have a specific gravity of 1.1 meaning 10% heavier than water.  So, if there is any water seeping into the fiber it weighs LESS than the Glue would otherwise weigh permanently bonded into the fiber. 

Said another weigh, porous fiber will always be ligther than glue filled fiber whether or not it takes on water.

Hang on a sec here-what are you using Gorilla Glue for?

 Beasho did you leave the bottom.with peal ply texture?
Similar maybe to sharkskin denticles?

quote author=Beasho link=topic=38521.msg440762#msg440762 date=1690303624]

Quick question. Why Kevlar? It's a hydrophilic cloth meaning the cloth itself will absorb water. It is also has a higher density than Innegra. Innegra is hydrophobic as well as being lower in density. I cant be sure, but you could possibly shave a few ounces off with different materials as well as avoid possible water intrusion into the fibers.  It's only a guess of course, but id be curious to find out.

The primary objective was to be "light in the ends."  Similar to America's Cup boats that were illegally fast because they had reduced swing weight back in the 1980's. 

The secondary objective was to be ding proof.  On my first board I used 1.4 ounce/Yard fiberglass.  The lightweight glass was intended to keep the XPS from flaking off over time.  However it does ding, or puncture, with sharper impact.  Even my big toe.  The Kevlar, on test samples, proved to be very ding proof against acute impact and was only 2.2 ounce/Yard.  Semi affordable @ $32 per yard from Fiberglass supply.  I would use Innegra if available, or affordable (??). 

The hydrophilic/hydrophobic didn't necessarily apply because I am not making my XPS boards waterproof.  To do that takes too much time, material, weight and quality control.  Ironically I have found that the moisture, if any in the fiber, serves as a natural evaporative coolant to keep the XPS from baking in the sun.  Although I have kept the boards out of direct sunlight when not in use. 

Between the 2 boards I have > 120 sessions combined and they are both holding up with no random XPS delamination that people seemed wary of. 

Now when I look at a board with full Carbon layers tip to tail I just see unnecessary dead weight.  The nose and tails of SUP foil boards serve no purpose but for flotation on takeoff.  They only need to be strong enough to not to randomly snap off.  The America's Cup'ers were pushing the limits of this idea 37 years ago, and I remember some boats did break.  We will only know we've gone too light, too far when things start to break off.   

IMO most production boards are way too heavy focusing on aesthetics and given the amount of box failures NOT investing in Track strength.  I went the other way and Invested heavily on deck structure and in the track support with carbon rods and XPS infrastructure but still less than a Full Divinycell high density stringer design.  I Divested of strength in the ends, waterproofing and showroom finish.  This board ended up 2 to 5 lbs lighter than comparable 115 liter boards. 

In a world where people are talking about 1% improvements in foil efficiency its crazy to me that board weight, meaning advantages of 15% to 50% are largely ignored.

"The fiberglass boat was found not illegally light in the ends, unfairly enhancing its speed, and was not in violation of the rule prohibiting a more beneficial weight distribution than an aluminium yacht."

Thanks again dwayne.
I spec'ed it out stringerless with 1.5 pd and this showed up.
As the owner of Swell Composites did it as a favour, i told him id use them or find a home for them-not sure that's gonna happen now.

Just noticed your blank included a stringer. That is where all the extra weight came from.

With 1.5# and our boards being super thick, no need for a stringer. You’re also not barrel riding. Stringers are a mistake for our use.

So I’m going to say they did use 1.5 lb (1.35 actual). You still need a carbon deck patch. Stringer won’t stop heel and knee dents.

I’d just do light glassing and single carbon deck patch, just where you stand. Single 6 oz top and bottom and treat as fragile.

Dwayne as a salvage operation, is there any value in wrapping the heavier foam blank in lighter glass/carbon? I was almost tempted to get my hot wire gun and cut out large sections of foam, to splice in some light density 1pd at the core.

1.35 lb EPS (ordered as 1.5) would be around 5.7 lbs for 120 liters. They used the wrong foam.

Production boards use 0.85 lb (ordered as 1.0). But, by the time you add all the sandwich and laminate required, weight comes back to where you’d be with simple 1.35 foam and glass.

I had this grand plan to use 1.35 mid span, and 0.85 nose and tail. I bought the EPS, then after a day of working with it, tossed it in the trash. It’s been 15 years since I last held 0.85 lb. Forgot what garbage foam it is. Went back to all 1.35 construction. My board weight beat Armstrongs published weight for same volume, so very happy.

Anyone have a range of what's acceptable blank wieght f a.shaped 8ft'ish DW board? I recently picked one up that was carved out by Marko. 8'1*22 @ 120L with a stringer coming in at 7.5pds. Feels heavy.

I’m done with hard to turn big wings. Just don’t have the patience to learn to ride the 999. The cool kids say the 1201 is the bomb. Hmm. Love the BSC 890 for winging and Spitfire 1100 with Foildrive. Probably would have had more success with an HD mast but oh well. Buyer pays shipping and PayPal fee.
Some Scratches from laying tips in sand. Each wing used no more than a few times.
