Is volan glass stronger for the following application? Preventing small dings as a result of not wearing a leash at rocky pointbreaks and the resulting rock bounce that comes from falling.
It comes in the heavier cloths: 8 and 10oz, so yeah, it’s gonna be stronger than 4oz silene. Though, one thing I’ve noticed about volan is it tends to dent differently. It seems like it might handle pressure dings a little different. Anyone else know something about this?>>> Is volan glass stronger for the following application?

My guess would be since you have a thicker laminate with the 8 to 10 oz you are getting a higher compression strength due to more resin in the laminate. The resin matrix has the dominating structual properties when it comes to compression, not the glass. But then I am probably full of it. Sluggo
In January '97 I shaped a 9’2 spoon using Walker Foam. It was glassed with a single . volan bottom and a double volan deck. The cloth is probably what they call 8 oz. (most likely 7.5 or something). I’ve never worn a leash with the board, and surfed it from Fort Bragg to C-Street. It has one ding, a small one near the nose. In ‘94 Paul Gross shaped a 10’ round pin for the shop out of a Clark Supergreen blank. We glassed it with double 6 oz. sylene on the bottom and double 6 plus 4 oz. sylene on the deck. Within a year the deck was caved in from so many dents. The glass shattered if you breathed on the tail. Is it the volan? Is it the blank? Is it the sander? A combination probably. All other things equal, blank, glasser, etc., I’d use volan over sylene anyday. Would I glass any board that wasn’t a displacement hull with volan cloth? If I could find 4 oz. and 6 oz. volan I would. If you’re put off by the color, and it does look somewhat industrial, use pigment. My 2 cents.

The resin matrix has the dominating structual properties when it > comes to compression, not the glass. I’ve heard the same thing about volan, Sluggo. I was also told that that is why graphite and epoxy are so stiff…that the graphite changes the matrix of the epoxy. I’m sure someone out there knows a lot more about it than I do. If you do, let us know.
Sorry. The picture won’t be posted again.>>> In January '97 I shaped a 9’2 spoon using Walker Foam. It was glassed with > a single . volan bottom and a double volan deck.

same here…volan=longevity. Just curious to know where the surf spot is in Ft. Bragg. I was there at glass beach a couple years ago during a solid swell and snapped this shot. Lots of rocks around there.>>> In January '97 I shaped a 9’2 spoon using Walker Foam. It was glassed with > a single . volan bottom and a double volan deck.

I am far from an expert, but I do have some training in low tech and advanced composites. Enough to get me in trouble. Some basics are: Looking at tech data sheets on fibers, stiffness is listed under Modulus. The higer the modulus, the stiffer the fiber. Typical E-glass such as Volan has a modulus of about 10.5 MSI, S-glass is at about 13, and lower cost comercial grade carbon is around 33 MSI (the higher the number, the stiffer). What is known as Graphite is 55 to 140 MSI, very stiff. Graphite is actually high modulus carbon, to make it there are extra steps in the process. The term graphite is misused in the sporting goods industry what they usually mean is standard commercial grade carbon. The cost difference between a low modulus carbon and High modulus graphite are huge. A 5.8 oz commercial grade carbon 50"(33 MSI) goes for around $17.00 a yard, while a medium modulus can cost about $60 per yard and a high modulus product can be around $300 per yard. One note on carbon, except in the case of cosmetic applications, carbon should be used with toughened (high elongation) epoxies to get the best results. They actually don’t bond real well with polyesters. With polyesters you need to almost encapsulate the fibers, which adds a lot of weight. Kevlar (aramid) and Spectra bond even worse to polyester (or everything for that matter). Kevlar is severly effected by UV light, if you left a piece of kevlar in the sun for two weeks it would lose half of its physical properties. It also soaks in moisture which is a huge problem in aircraft since a lot of the honeycomb used in sandwich construction for aircraft is aramid based paper. Probably not good for surfboard applications. There are quite a few FREE trade magazines for composites, I think the best one is Professional Boat Builders. Here are two: Professional Boatbuilder www.proboat.com Composites Fabrication Magazine www.cfa-hq.org/cfmagazine Probably be best if you said you were a boat builder or something if you sign up for these magazines.

Usually this is caused by overshaping the deck of a Clark Foam blank and/or over catalysation of the resin. Also adding excess stryene to the resin will make it brittle. Over catalysing resin and adding excess styrene, or worse acetone are huge problems mainly caused by piece worker mentality or lack of understanding of the effects. Both these things cause brittleness of the resin and yellowing. Pressure dings have less with the glass and more to do with the resin matrix. Clark Foam blanks have a density gradiant, making deck rockers more crucial to the longevity of the finished board. If you are going to overshape a Clark Blank at least use a Classic weight blank. sluggo

Very tuff stuff but i have to say my mask goes off to you for surfing without a leash… The best way to stop those dings from the rocks and logs up here is “DON’T FALL” If you do you deserve a few dings and a nice swim… The dings are marks of character… Wear them proud… http://surfnwsc.com
