    FRP Questions

    I have a question about FRP Fiberglass reinforced(Resin?) plastic. I did some fiberglassing 25 to 30 years ago - just a bit and if I remember correctly Fiberglass resin was a two part epoxy kind of finish.

    I have seen FRP in a number of stores here but never thought of using it until recently. A couple of days ago, I looked at some and in my best Japanese could not see anything related to "mixing" in the instructions, nor could I find a catalyst mixture any where near the pints, quarts or gallons of FRP to mix.

    The instructions only said it takes 24 hours to cure/dry (in Japanese of course).

    SO my Question is:
    IS FRP a one step process or a mixture process?

    I want try it to see if it can "stabilize" wood for pen turning. It will be used in a vacuum/pressure pot. FRP is quite common here in home centers and it would be a great help if I could figure out the instructions.

    I posted a similar question on the Pen Turning forum but I wanted to hear a woodworker's point of view on FRP and its use. Thanks.

      While I don't know the answer to you question, let me give you a warning, FRP is a common term, used to talk about fiberglass reinforced paneling. Any searches will bring up a lot of that stuff, as it's used commercially (restaurants, butcher shops, even car washes).

          Doh! ... and here I thought someone was actually going to discuss using what I've known FRP to stand for: Fibre Reinforced Plywood ... http://www.fiber-tech.net/FRP.htm ... but I just realised that they also call it Fibre Reinforced Plastic too ...

          Not sure about the stuff your looking at using ... I'm thinking you might be referring to GRP (Glass reinforced Plastic)? GRP.... but AFAIK they are all 2 parts that I've seen ... as in a mixture process ...

              About 30 years ago I built a fibreglass 38ft centre cockpit ketch. In those days boats were built using polyester resin and various forms of fibreglas i.e mat, roving, cloth, etc. using the hand layup method. Nowadays vynilester resin is used frequently for below the waterline, because there is less chance for osmosis blistering. Methods of construction such as vacuumbagging have improved the glass to resin ratio.
              A very very small amount of catalyst is mixed with the resin to "kick it over" to a solid. The ratio and temperature determines the working time.
              The surface of a layup stays tacky for a very long time, which makes for a better chemical bond for successive layers. If you needed to work the surface for "fairing" the hull, you'd buy waxed resin. A small amount of wax was mixed with the resin, The wax would migrate to the surface of the layup, excluding the air and allowing the layup to cure right to the surface. You could the grind the bumps and fill the hollows to fair the hull.
              Of course fairng is not necesary in production boat building because the hull is layed up in a mould.
              Boy, this brings back memories, I can still smell the resin!
              Sometimes my mind wanders. It's always come back though......sofar!

                  Thanks for the comments. The letters "FRP" are written very large on the cans, but I have not seen any hardener anywhere. I guess I will have to ask.

                  This is where the problem comes in. In Japanese choosing the right word is essential or you can cause one huge misunderstanding. AND with specialty words - these are words that you don't know and the average Japanese friend or acquaintance have no clue. Most dictionaries don't have this type of technical words in them either.

                  I went into a home center some years ago and wanted some bug poison. Let me tell you quickly - you can get some strange looks by asking for bug poison and using the most common word "poison" as listed in the dictionary.

                  I run into this kind of situation often, and after 9/11, I have to be careful. As a foreigner, asking for Acetone can get one into trouble. Speaking of Acetone, I have to buy sandpaper and other items related to paint when buying acetone or I get some strange looks. Same for Gas. I can't buy gas in a gas can unless I take my weedeater with me in the back of the van.

                  Sorry about the run on, but asking for things without the right word - is a problem here. I just wanted to make sure what was needed before I attempted to ask.
