Anyone know of a good source for Mylar for laminating purposes? Conway had suggested using it when using Aerosleeves or similar for reinforcing airframes.

Thanks.

The BEST place is right here in Ft Collins. A place called Ft Collins Plastics. Its .01 thick and is what Ive used for years for my Compression wrapped lamination method. In fact recently I was approached by a large rocketry vendor (wont say who but we all get stuff from them) and asked the same as well as if they could use my method of laminating tubes for resale. They are also the place I get my 2 oz and 6 oz glass as well as my Kevlar cloths. I also use Aerosleeve as well alot to. But hit them up there and they will have what you want. its sold by the linear ft. and is I believe about 48″ wide.

Thanks, Conway. Thats perfect. I’ll have to get up there this week if I can get away from work. Or maybe on Saturday. OK, so after sliding on the aerosleeve, wetting it down real well, I wrap the mylar around the tube (just long enough for one complete wrap plus an inch or two), then tightly wrap the mylar with duct tape?

Correct in a spiral wrap from one end to the other then set on end and let dry.

I would highly recommend using if possible a 2 oz wrap around the outside of the heavier glass cloth. What this do0es is makes for a better finish with less pinhole filling and sanding work. I also would recommend having a 2nd set of hands slow curing epoxy and use it kinds heavy as we want it to for a gel coat basically but still yet be squeezed off. If all that makes sense.

Conway,

Do you have use a release agent on the Mylar? I’m curious because I’ve got project coming up that I want to fiberglass. Are any of the fiberglass/composite gurus of the club willing to put on a hands on clinic?

The Mylar itself is a release agent. It needs none as the epoxy will not stick to it.

As far as a demo/clinic..sure. Let me get past LDRS and I would love to show how to do my compression technique.

Conway,

How about a clinic sometime in August? It’s after LDRS and we still have time to use our new knowledge before Oktoberfest.
