Question

I need to restore the floor in my 25' paker and want to use a composite material. my floor thickness is 3/4 (.75) of an inch thick. Can this product be fiberglassed over? Will the fiberglass stick to it, or is there a better solution? Email or 561-722-7248 ask for Oakley Brown Thanks, Oakley

Top Answer

It is a core so it needs fiberglass to have strength. Bonds to fiberglass, kevlar and carbon great. You can hand layup fiberglass and epoxy great.

Answer

of course it can be fiberglassed over...but for strength it needs to be fiberglassed on both sides or at least bonded with mat to the old floor JB

Answered on 04/26/2012 by JOHN BENNETT

Answer

Yes, this is a core material that is intended to be encased in fiberglass or epoxy resin and fiberglass cloth.

Answer

Are you removing the 3/4 inch floor or just covering it? Replace ...This product needs to drink your resin to gain it's rigidity & strength. If you need 3/4 inch, use three 1/4 in layers to maximize absorption. Great stuff and I recommend to glass over it with a heavy roving for sure. Your losing weight. Restore ...If your just going over the old floor,sand it rough and just fiberglass with a heavy roving cloth and a good barrier coating before finishing. Your gaining weight.

Answer

On second thought, 4x8 cellular pvc sheeting and fiberglass would save you a lot of time, it floats and cuts like plywood. Look into it.

Question

Is this a good replacement for balsa wood core in a cockpit hatch?

Asked on 09/22/2011 by Brian Woodward

Top Answer

Yes it's a perfect solution. You can remove the lower layer of fiberglass and the old balsa core from inside the hatch cover. Replace the core with divinycell and reglass. This method preserves the top skin with the no skid surface. You can beef up the upper skin with a layer or two of fiberglass placed first before the core. If you do this, you may need to select a core material that is slightly thinner than the original if need be. I repaired two large hatch covers this way last year.

Answer

It depends on the application. I'm sure it's not as strong as balsa, but it's lighter. If the hatch will be subject to loads such as walking on it, balsa may be better. If the hatch has a crown to it, and the layup is stout, the divinycell may work just fine. I hope this will help, Tom

Answer

Brian, I have used the Divinycell for a core for a 6'x3' platform. I used a 1/4" core with 2 layers of glass on either side. I did the layup with vacuum forming. It is as strong as 1/4" plywood and is alot lighter. If you need more help, please let me know. Chris

Answered on 09/24/2011 by CHRISTOPHER COTTON

Answer

Hi Brian, In most cases divynacel could be substituted provided the face sheets are bonded securley. However we typically use nomex honeycomb core for structural applications in aviation which is not as moisture critical as boat applications. In failure mode analysis it is the facesheet bond that fails and in turn causes the panel to fail. End grain balsa offers comperable compression strength as divanycell however the peel strength may be different. Structural data on flat panel composite construction is available from many of the suppliers of flat panels. MC Gill Corp, Technical Composite Corp, Hex Cell etc. I hope this helps. Tom

Question

Will this bend at all? I'm gonna build a hard top to replace my fabric top and need a slight bend over the eight ft length. Would want to use 1/4" or do I need 1/2"? It will have plenty of support underneth. Thanks

Asked on 01/01/2012 by michael nelson

Top Answer

If you are going to substitute your canvas over the existing frame work, without complex curves, solid 1/4 inch will be fine installing with gourmets. I would use 1/2 in plain sheets to surround the framework with shapely side panels, extend a little fore and aft and give a customized "cap" look. Shape it to the frame work covered with wax paper and apply a coat of resin to lock in the shape. When dry, take it off and apply more resin to both sides. Sand and finish before installing. Good Luck, Vito

Answer

Yes, it will bend slightly, especially over a long distance. The thickness depends on the strength you need. You can increase the outer fiberglass skins you make to increase strength as well.

Answered on 01/15/2012 by MICHAEL KOWALESKI

Answer

It will bend...in one direction. Use this for parts of the cabin top that DO-NOT have a compound curve. Use the scored product for areas where the curve wraps in more than one direction. I prefer the unscored sheet because the amount of resin that you will need is predictable. The scored sheet needs its cracks to be filled before applying the laminate. On the job I did ( replacing a 30 year old somewhat tired balsa core cabin-top) I scored the exterior laminate and peeled it off in manageable pieces. I then chiseled off the balsa and left the existing side of the original as the base. The key to making the foam bed properly is WEIGHT. I used hundreds of pounds of chain that was lying around the boatyard....and bricks, cement blocks and lumber and wedges. A single bedding layer of mat and epoxy was all that I needed. To replace a fabric top....you're going to need a make a mold....use a 4X8 sheet of masonite...decide which is the good side...(probably the top). Use mold release plastic, lightly glued to the smooth side, spray on gel coat...and then do sandwich from there... 1/4 vs. 1/2? Think of core laminate (done properly) as having most of the properties of solid laminate except for penetration. Either way it's going to be somewhat "noodily". If the existing structure is sufficient to support it..fine....But remember you want the hood of the car doubly latched. JB

Is this a water-proof foam? I'm wondering if I can use strips of this foam to make a hull.

Asked on 02/10/2015 by Justin Choi

Top Answer

It is a closed cell foam so it is water proof. If you glassed both side of the foam and had some ribs and bulk heads I'd say sure.

Can this be used for a transom replacemnt?

Asked on 08/17/2013 by Daryl Piner

Top Answer

This could be used as a core for transom repair, but it may not be thick enough, depending on the thickness of the original core.

Answer

It's not strong by itself, usually used between layers of composite material. you'd be better off with a good grade of plywood laminated in a few layers, covered with fiberglass.

Question

Do you have to glass the boards for making a floor for boat?

Asked on 07/02/2012 by Undisclosed

Top Answer

Yes, absolutely. The sheet is a core material. A fiberglass skin must be applied to both sides; in other words, the sheet is encased in fiberglass. This is typically done in place as the deck is built - the bottom fiberglass layers/resin are placed. Then the divinycell is embedded in resin, and the top fiberglass layers/resin are placed.

Yes, by itself, it has very little strength. It's meant for use as a core between composites such as fiberglass or carbon fiber.

It's foam so it will break so you have to put glass, carbon or kevlar over it. You can paint that with anything that goes over epoxy. I like the brightside single part poly urithane.

Question

I am looking to build a hardtop for my Albin 25 (10' 2" x 7' 1"). Would like to have as clean of an appearance as possible.......meaning I would like the hardtop itself to provide the strength and rigidity rather than a frame structure that I will bang my head on. The hardtop will have a slight arc in its width and the longest unsupported span just over 6'. Would 3/4" divinycell core be adequate?

Asked on 03/27/2021 by Tom from MI

Top Answer

The divinycell should be fine, once it's epoxied and glassed it should be well strong enough

I wish to build a prototype strip canoe using 1/2" form core. Which will work best with epoxy resin, Corecell or Divinycell? Why will it work best? Thanks

Asked on 12/03/2020 by Jon from MI

Top Answer

Both products will perform well with epoxy and there is no discernable advantage of one core material over the other. The only difference is the type of polymer they use and the sizes/thicknesses offered.
