I think the issue with cuben has always been the lamination of different materials. Surely the solution is to just weave the materials together like normal fabric. I mean by laminating things together you are not just trying to use a new material but reinvent fabric. Reinvent a proven 1000's year old technology, like trying to reinvent the wheel.
I'm, (thinking) they went for the laminating , because the fibers can stay
aligned in a straight line better ; if so then ya get a 30% increase in
strength, over a fiber that's bin woven ??
Biggest problem with laminating stuff is if the glue
breaks down , the product will fail ; and like "foilholio" mentioned
it's not as likely to happen when stuff is woven together !
Watched that happen when Hang gliders went for the laminated
Technora sails , and they were stiffer (for a year or two) until the
expensive sail needed replacing ; but the woven Dacron just kept
its integrity for sometimes Decades, before it went By-By.
A great example is my Rigid-wing HG , which was made in 1997 ; the
thing still flies GREAT , and the Dacron woven sail looks like it
could last another 10-years !!!
