Hey guys and girls, I've been doing experiments with N-Fusion surfacing veils.
Different lay up schedules and different results. Testing for impact strength, stiffness, cosmetics, and weight.
N-Fusion is a brilliant white non woven cloth, It is lighter than fiberglass, but with different properties.
- Soaks epoxy like a sponge, so must be done under pressure.
- When between cloth and foam, it increases the bond. This is because it has micro fibers that mechanically join the two surfaces.
- When between two layers of glass, it spreads the compression and tension planes, increasing stiffness. Think less damage from blunt inpact.
- It does much less than the equal weight of fiberglass to resist puncture. It won't do as much as another layer of fiberglass.
- It is designed to be a surfacing veil.
I just did a mock -up last night. I took a scrap of foam. Laminated it like normal. Pulled off the extra epoxy like normal. Layed a 2 oz swatch of N-Fusion on the wet laminate. I added no extra epoxy to saturate the N-Fusion cloth. Covered it with 20" wide shrink wrap, purchased from Home Depot. Pre vacuum, the N-fusion was almost dry. I put in in a Vacuum bag, and waited till cured.
The surface was perfect! Perfectly saturated with the surplus epoxy that would have been normally just dead weight. No weave showing, just the slight texture embossed in the N-Fusion.
It can be purchased directly from Cerex in larger quantities. It comes in many weights. It also can be purchased in smaller amounts from Graphite Masters.
If you contact Cerex on their website, you can request samples. You have a choice of a bunch of different weights, or one larger sample in a specified weight.
Now for the disclaimers.... According to an industry insider, several large major board makers, Lost, Rusty etc. are already using the .7 oz between the foam and glass for better adhesion and whiteness.
I asked Mike Daniel if he was cool with posting about the stuff and he gave his encouragement, so I'm not stepping on any toes. I don't know if Coil is one of the users of this stuff, but some of their work appears to be in this direction.
There are users here on Swaylocks who have early knowledge of this.
There is also a user here from Graphite Masters who was helpful.
I ask them to jump in with their findings.
This was just sort of a quickie posting, so if you want more info, ask away....
