From: "Russ Fisher" Subject: COZY: Peel ply Date: Thu, 15 Jul 1999 19:42:31 -0400 When I ordered my first batch of materials some time ago, I ordered a roll of 1.7 oz x 45" peel ply from AS&S. About a year ago, I reasoned that I wanted to make sure I had enough to do the fuse inside and out, so I called and was told that they had discontinued the 45" stuff and only had the 66" width. It was wider than the rack I had built to hold cloth, but I figured I could work that out. I never opened it until the other day when doing the 4ply uni lay-up on the longerons. What AS&S DIDN'T tell me was that the wide stuff is 2.7 oz, making it CONSIDERABLY stiffer than the other. It was immediately obvious that there was no way this stuff would lay down over all the complex curves of that lay-up. Fortunately, I still had enough of the other to complete the lay-up. Enough rambling, the question: does anyone use this heavier stuff? Maybe for flat or slightly curved lay-ups? AS&S now says they have the light weight peel ply back in stock so I can order more, but don't want to mess up a large lay-up trying to use the heavy stuff if it won't work. Thoughts?

When I heat it with a hair drier it seems to take up the correct shape albeit not as well as the light stuff. See you at Oshkosh again this year if you are going.

I received a lot of good advice, most of it sent directly to me rather than to the group. The consensus seems to be that the 2.7 oz is fine, just a little trickier over curved surfaces. I think I'll save it for the wings, strakes and other relatively flat surfaces.

I am planning to order the kits for chapters 4 - 7 plus some other various supplies like epoxy and some tools. I believe I have it all figured out except for the peel ply. I haven't done chapter 3 or any other composite work before so I'm not too sure how the stuff is used yet. Chapter 2 mentions 4 rolls each of 1" and 2" rolls. I've seen mention of people using 4" and 6" rolls. What size and how much should I order for chapters 4 - 7?

I'd recommend ordering the 4 rolls of 1 and 2 inch, plus a few yards (say 10) of the 60 inch stuff sold by Wicks. These supplies may well last you past Chap 7, but you'll be able to get the feel for each of the widths. I use the 60 inch stuff most. You can cut it as needed.

It is light weight and easy to wet out. Don't get "acetate", it looks the same but the epoxy eats it up. I think you can beat the fabric store prices by ordering peel ply from Northern Fiberglass Sales. I have never ordered from them but their price was a lot lower than the fabric stores around me. I think I'm paying about $3.00/yard. Also, try to get a plain weave because the stretch-fabic weaves don't peel off as nicely. I use the peel ply on about everything to aide finishing. --Kent Ashton Date: Sat, 9 Oct 1999 22:14:03 -0400 Subject: Re: COZY: Peel Ply From: Dana Hill Per the recent reference to Northern Fiberglass..... yes they are a great source. When I bought from them they quizzed me about my intended use. They then knew exactly what I wanted. I got a partial bolt for the same unit price I was paying for suspect fabric at a fabric store. They were great and I believe they can mailorder. They are in the Portsmouth, New Hampshire area.

We learned that hard-weave (not fuzzy or stretch weaves) nylon, polyester and dacron work well. Watch out for cotton and rayon. I would examine the roll ends table where things were reduced for clearance. I was able to purchase several rolls of nylon like is used in ski jackets for $.45 per yard, and later wished I had bought the entire table. I learned it is best to take a sample home, use it on a wet layup, and peel it off after cure, before buying a whole bunch. I found some that were completely unuseable. I also became friends with the people who made "envelopes" of Dacron to cover the wings of fabric covered airplanes. They ended up with huge boxes of scraps which they threw away. All I had to do was pay the packaging and shipping costs and they would send me as much as I wanted. I learned it was necessary to iron the material flat to prevent the wrinkles transferring to the layups.
