foam core
I'd like to build a 4x10 fiberglass on foam core panel. Medium to
light duty cover for a center well. I plan to sit/row on top of it and use it as a roof for a canvas cabin. Can I use the blue or pink closed cell foam from home depot or do I need special foam. I realize I can order end grain balsa or specialty foam but the home depot stuff would be a lot more convenient and I'd like to keep this experiment cheap. Will the expoxy/glass stick and will it have the properties neccessary to function in this capacity? Thanks in advance. Tom |

Resin will eat the styrofoam panels you mention in your post. You can get
urethane foam in whatever thickness that will serve your purpose and is compatible with epoxy, or polyester resin, and probably vinyl. MAC "Tom Best" wrote in message om...

Can I use the blue or pink closed cell foam from home depot or do I need special foam. Where would one procure urethane foam cheaply and easily? 1. Resin will NOT disolve the polystyrene foam if the resin is epoxy resin. It is the styrene in the polyester that melts the polystyrene. 2. Under pressure from the crowd :-), we tested (again), blue polystyrene insulation foam with epoxy and glass. Resin bond is perfect but the foam has no shear strength and the sandwich has no peel strength. Under stress, either the core falls apart or an outside layer of the insulation foam will break. We took pictures and will show them soon either at BoatBuilderCentral.com or at our tech. support web site Bateau2.com 3.I have 30 years experience building and designing foam sandwich boats and would never use anything else than quality marine foam: Airex, CoreCell, Divinycell etc. Airex is expensive and outperformed by others. It has a low heat deflection. Corecell was my preferred foam until the compnay ATC went bankrupt a few months ago. SP bought them but production has not resumed. Right now, we sell Divinycell (same as Klegecell). 4. It's not cheap, you can't find it cheap and if you find a cheap one, it's no good. Jacques from bateau.com |

Hello Tom Getting some good replies here. Where are you? Unless you are Okkie Wunderslug, in which I am sorry........for many reasons. (1) A centre well is not necessarily "light duty" (2) Use only structural foam. Not urethane (3) Ever tried rowing a 4' by 10' panel? I'm in Austin, Texas. From what I've seen, the hardware store foam is not a great idea. Also, the structural foam seems extraordinarily expensive. I may change my plans and use 1/4 plywood or balsa. Thanks to all. |
