More glass?

Post by fallguy1000 » Tue Jul 03, 2018 9:01 pm

You all know I am building a spec'd boat.

But you don't know that triax I used has the 0 strand running on the exterior.

Some of the fancier triax is stranded +45/0/-45, but mine is 45/45/0.

The 0 strand is always on the outside in layups, or further from the core.

The concern is if the 0 strand ever starts to go; not sure the fairing or paint will stop it.

So, I have been considering putting a light layer of woven over the hull. 4 oz or 6 oz

The hull is about 22 yards on each side. Or 44 total. If I use vacuum; figure the resin at say 66 percent or so.

44 yards of say 12 oz per yard is roughly 35 pounds added weight for the benefit of 0 strand reinforcement.

Thoughts welcome. Thanks.

Go where? You're worried about nothing IMO. If the 45 was on the outside what would be the mechanism to have a fiber layer to remove itself from the resin matrix?

Save the effort. I don't think it's a real problem.

It peels awfully easily. Any hull impact at sea could be super ugly. Especially the waterline and below panel.

If the 45 were outside; it can't go 32', but about 4'.

Not sure if you know Darren Clements, but he tells me the outboard/dock side of these boats really tend to catch it as well.

He told me to go much heavier.

If I wasn't away, I'd add a picture of the issue...next week...

Why don't you simply turn the cloth over and put the 0 on the inside? Is there a reason this can't be done?

Fallguy while the 45/45 is providing the strength. The 0 is a layer that provides protection and additional strength. It is epoxied to the other two layers. I think you are over thinking it. There is no need to cover it. You will have layers of fairing material on it.

Well that is my two cents. :D
