Hi Netters. Larry Flesner asked about the tan colored fabric called dynel. Ken Rand used it to build his first planes. At first glance it looks good. It is thin, drapes nice. When you add the liquid epoxy, the fun begins. It swells and takes a lot of epoxy. One of the characteristics of dynel is

My curiosity is probably a bit outdated. The original KR designs called for a material called Dynel. From what I have read, this was more of a draper's synthetic fabric like rayon etc. - not intended to be a structural medium. It is however reported to be very effective (strong / tough?) when us

Steve, I had one of the first sets of plans for the KR-2 and ordered the Dynel. It was very easy to work with and formed well to compound curves. When used on the bias (45%angle) it would conform to a tighter corner than fiberglass. It did fuzz up when the epoxy was applied, but I think it did s

Ther are several reasons why dynel is no longer used to cover composite aircraft. 1) It is not as strong as you are lead to believe.One layer of boat cloth(6 oz) is far stronger than 1 layer of dynel. You can tear a layer of finished dynel apart with you hands but you could not do the same with gla

I think Ken Rand used Dynel to make it easier and cheaper to build the plane.

The original KR was covered in dynel. It is the most terrible stuff. It is a maximum problem to sand as it is very slippery. When the epoxy is added the cloth sticks up its fibres in all directions and soaks up too much epoxy. It certainly is NOT strong as compared to fibreglass.To apply glass a
