Thanks Don The substrate material was not what bothered me on this type = of construction since they all are all as limp as an old man's ...(well you = get the idea). Once the resin is added however all these properties go bye = bye. Many forget that composite is just that, a composition of different materials to result in something much stronger than any of the other materials used alone. The idea itself is good but I cannot see where it could be of use to us unless as you stated. If going to imbed aluminum = into the skin as a hinge then it would be as easy if not easier to install = the plans type hinges, or better yet the Dr. Dean type. Both have been = tested perform, are in wide usage and do not have a finite lifespan with proper maintenance and inspection. Just my opinion. Doug Rupert
