core material for boat decks

Should I stick with plywood or go for foam core? | Boat Design NetBut if the boat is larger and is kept in the water all the time you would be better off using a synthetic core material like Airex, just because you won't have the rot issue. And yes, you can .... I'd coat the panels with a very hard epoxy resin, let it kick off for a day, and then drape with 10oz woven cloth that has a very fine weave wetted out with ordinary laminating epoxy, Or perhaps two drops of 6 oz deck glass that is even flatter and easier to completely fill. (You can actually ...

Foam Core - Deck, Cabin, Bulkheads | Boat Design NetI recently purchased a 46' hull uncompleted hull from an out-of-business builder (core-Cell/Kevlar/Glass), and now need to construct the interior, deck, and pilothouse structures. I've spent several months researching materials and methods, and am strongly leaning towards foam core composite. I have opted for foam as opposed to plywood for weight and rot considerations. Similarly, balsa is out. I have Coosa, Last-A-Foam, and Divinycell samples, and will likely use ...

FIBERGLASS BOATBUILDING: Cored Laminates - Wavetrain25 May 2011 ... It is therefore common for older fiberglass boats to have had all or part of their decks recored at some point. This is a difficult, expensive job, and you do not want to be the owner of the boat in question when it needs doing. When water does penetrate a core, it theoretically should not travel far, as any reasonable core material will be a closed-cell substance that does not allow water to migrate through it. In practice, however, water in a core often migrates long distances ...

The Hard Core Facts - Power & Motoryacht31 Aug 2007 ... One application where most would agree that balsa shines is as a core material for interior decks and bulkheads. Its superior shear strength and stiffness make it ideal for supporting a wide expanse of open deck without need for intermediate supporting pillars or columns. And within the yacht's interior, the issue of water absorption is clearly moot. Closed-cell foam. Poly-vinyl-chloride (PVC) is a closed-cell foam popular with many builders of larger, upscale yachts.

Core Materials of Sailboat Construction | Cruising World20 Feb 2014 ... At Dufour Yachts, workers stack dry, precut fiberglass panels on a deck mold in preparation for its resin infusion. The layup includes a foam core, the green sheets of which you can see in the left of the photo. In the first installment of this two-part series (Decoding the Matrix"), the composite parts we described were solid FRP laminates, also called single-skin parts. They're composed entirely of fiber and resin. But another critical development in composites technology ...

Laminating a new skin will be a lot more difficult, consume a bunch more material, effort and money then bonding the old skin back down and filling the well tapered seams. Also noted is the ... Since I was repainting the entire boat, it was no problem with doing the rework since I did not have to "match" any deck skid pattern or paint. By the way ...

What material for recore? | Boat Design NetThis is my first post so I dont know if this is appropriate, since it is about repair. Is that subject appropriate here? I have a 40 year old sailboat and the deck has a soft spot at the bow. I removed the skin from the bow to 3 feet back. There was plywood and balsa as a core material. The plywood was intact but wet and not bonded. Balsa was mostly gone. I have to decide on a 1/2 material to use for a new core. So many people use balsa or plywood. I am interested in foam.

Structural Issues : Core Materials - Yacht Survey Online31 Oct 1998 ... That notion is well and good but for one thing: boat builders understood this, but no one else did. So people went merrily on their way drilling their decks and house tops full of holes to mount things. Water then got into the core and 10, 15 or 20 years later we're back to floppy decks again because the core eventually rotted. Next, they started using balsa to stiffen up hull sides because builders realized that they could cut some material out, ostensibly save a little money ...
