New cloth material Ineggra S, anyone try it yet?

I may be incorrect, but I believe this is cloth is a variation of polyethylene.  I think a major issue is adhesion, the resin may not stick very well to the cloth.  Take a look at a table of modulus of elasticity though, and you will see polyethylene right up at the top.

innegrahavent had time to try it

this is 2 oz

will let ya know?

Montie,

I am just now finishing a board with 4 oz plain weave Innegra S.  The core is 1.9 # EPS stringerless (from block foam).  I used a layer of 4 oz over the Innegra cloth top and bottom.  It makes for a light board that is very durable with good flex.  No vacuum bagging required.  The Innegra cloth didn't seem especially difficult to wet out but don't plan on wrapping it around any hard edges.  Its like Kevlar in that it doesn't sand.  It makes a very bright white board and adhesion with epoxy is excellent.  It is going to be a little more expensive than S glass I believe.  Seems to have a lot of potential and is recyclable.  BTW  it is polyproplyene.

regards,

Dave_D 

Hey MD,  Aren't Island surfboards down at Ocean Sport's world?

What's the dent quotient  in a lam with a single layer of 4oz?

hey josh i will e mail you  monday

fellas this is not the same fabric that was doing the rounds a year or so ago?

Josh,

Since it is plastic it just wants to fuzz up.  I had a spot or two where I sanded through and I just did a small repair over the area.  The stuff I used came out super white and was somewhat transparent.  I will take some pics today.

Dave

Huie.. i have almost finished my first whole roll of the stuff. my glasser hates it as its like violane to wrap around rails. we always put under 1 layer of 4oz. first impressions were it has a high dent resistance but after a couple months i would now say it has a high dent Resiliance. it is reasonably opaque and i have used it over foam sprays. it tends to soften the color a little. the weave look is prominent. i have been calling it "Ghost carbon" as to customers it looks like carbon or kevlar but white. my favourite thing about it is that it does not seem to alter the flex feelings of a board compared to the difference you normally get with carbon "stiffer etc". so carry on boys enjoy testing! oh josh contact Colan direct

Sounds like a good candidate for vac bag laminating to me.

Maybe DAVE wants to keep it for himself so he's trying to throw us off the bus?

Huie, i think its the heat treatment thats made my glassers soft... (they work upstairs in a tin factory) haha. i thought i gave some clear feedback on my experiances with Inegra. i actually like it to use on boards. but like anything a little different to the norm you have to adapt your techniques to suit it. it definilty does suit vacuum bagging and some of those nice projects you do Huie. 

feraldave,

do you have any tips on what to do differently when glassing?

do you use innegra and standard 4oz together and if so do you wet them out at the same time?

i have some samples of the 2 and 4oz to try for my next one and as i only do 1 a year i dont want to stuff it up.

what would be the optimal usage for it if i have some 1.5lb eps?  i am tossing up between just the cloth and epoxy or doing a bamboo veneer in between the innegra and 4oz.

thanks,

Scot

On the WMD thread Huie mentioned doing a 2oz prelam of this stuff and using it like a veneer. This is something I've been kicking around since this thread came up.  I like the idea of bagging on a veneer but to be honest the idea of a transparent or semi-transparent cloth-based veneer is a lot more visually appealing TO ME than using the various woods.

Originally my thought was to just bag the cloth directly onto the deck and bottom like an insert without even trying to wrap the rails, or perhaps just skip the bag altogether and wet lam them, and then do a regular wet lam with the outer glass as usual.    

I have several questions - Does anyone have an opinion of how a layer of this 2oz or (if available) 4oz compares to a layer of the bamboo?  Is there a strength or compression advantage to doing a prelam of it and then bagging that vs bagging a wet lam directly into the deck or bottom?  If you did do a prelam would it wrap to the contour of the deck or bottom when bagged?   

I've got two boards that are ready for glassing right now and I wanna try this stuff but I don't want to reinvent the wheel if I can help it.  If anyone has any input to share I'd greatly appreciate it.  If not then I guess I'll just pull the trigger and let you know how it goes.

thats 2 oz           yea under the skins  patches

interested to try some as deck patches with the lightest blank I can get.....

Ineggra

mmm. nice Huie. i think i might get you down here one day to do some finish coat lessons to my production staff! i too use innegra under 4oz. only way i would use it on a bottom is vacuum bagged...

Huie what foam did you use on that board ?,I did a test board on the weekend with 4 ozs innegra on the deck with 4ozs glass bottom and a 4 ozs glass over the innegra on the deck ,I used  xps foam on this one ,6' 2 X 17,7/8 X 1,7/8 .finnished board with glass on fins came in at 2.1 kgs ,(all the glassing was done in one hit ,)

c d d is the best kept secrete on the planet.

CORE is critical.

The world will never know C D D it will be a ledgend like the man who created it!

I am making one now with this cloth.

I have lamed the 4oz Ineggra layer over the whole board, had a few hangers - the cloth does not like to be sanded. I brought it up to a 600grit and it looked like normal. dropped the probox in and I should be done by the weekend. I am going to put 4oz E over the cloth. I had bubbles from the tail edge where the cloth did not lap correctly so that was a pain to fix but the other lap took care of it after sanding.

So far it seems relatively strong, my finger does not dent the board if pressed down (to an extent) but I do not think the fiber that I am using is the tightest that they have. It looks more like a volan and loose weave.

Ill post up some pics when I get finished.

I wonder how new this material really is or in what way it is new. Innegra S is made of polypropylene, according to http://en.wikipedia.org/wiki/Polyolefin "Polypropylene is another common polyolefin which is made from the olefin propylene." On http://oneoceankayaks.com/Abrasion.htm#synanch they tested olefin cloths in september 2000 according to wayback machine, including a polypropylene cloth. So I wonder what is the difference between Innegra S and other polyolefin and polypropylene cloths. That said, it's great if this new product makes this types of cloth easier to obtain and get acceptance in surfboard construction.
