    I would like to build something similar to the SuperCat Sliver 29. Does anyone know of a similar design plans? And can anyone identify this building material?

    The bathroom wall picture is plascore as is the other core shown.

    Or some type of honeycomb core.

    Thanks. It looked like plastic but I wasn't sure what else was out there. I've used plastic honeycomb from carboncore.

    Plascore in Michigan was very boat builder friendly to me. My build is mostly Gurit Corecell, but we had a few areas where using corecell was going to require lots of joints. The plascore is available in larger sizes and I ordered 10 sheets of 5' x 10' material which reduces my labor a LOT. So far, the only question I have is about the bond strength between the veil and the plastic for hull use. I don't believe it is as good a bond as glass to core, although it seems like a better bond than some of my parts with interlaminar issues in 17 oz biax. Fortunately, ours is not for the hull, but for a cat cabin base. Plascore does have infusion grade stuff. Everything we are doing on the cabin and cockpit bottom is hand laid.

    Plascore is unbelievably affordable for larger and thicker panels. My costs came in at about 1/3rd, not even counting the labor savings on the larger sheets.

    If it is actually an aerospace material, it might be Nomex paper honeycomb core.

    Much easier to just ask the seller, rather than ask a bunch of yahoos.
    No-one can really tell the material from those pictures.

    A fair statement, but I haven't seen clear nomex. Usually, it has a color.

    And not sure why a head wall would demand aerospace core.

    Plascore is a good bet.

    Oh I didn't know honeycomb was available for vacuum infusion! But if it's closed honeycomb cells, can they still conform to curved surfaces or are they rather stiff?

    I don't wish to overspeak as upchrch rightly asks, but plascore has lower flexural rigidity than foam cores for the same thickness (this is from a discussion with them), so I assume it will easily take curves, and I am using it here and it is very 'bendy'. I don't know if I like the idea of torturing it much after laminating. The veil bond will be impacted ftmp. Even walking on a somewhat supported 24 oz triax single topside lamination had me cringe as I heard a crunch and got off it.

    And, the infusion version of the stuff does something odd like hole punching on 4" centers and your glass must provide channels for flow (and/or perhaps flow media above?). But I only know what I read. I don't believe they have an embedded flow agent (sic). I wish I could share more, but plascore is a very builder friendly company; give them a call.

    Above is 1" veil both sides; it takes this bend without any apparent problem.

    Well I actually inquired about buying a boat from them but they don't sell outside of their geographic market because it's too difficult and too expensive. I did ask about building material after that and no reply.

    Fallguy, interested in your comment "costs came in about 1/3rd". What is that compared to? Solid laminate? Plywood cored epoxy?

    Thanks
