pchapman 279 #1 December 11, 2013 Just curious what people are finding when doing tensile tests on low bulk fabric, which in particular would be PD Optimum reserves. Does one actually find less apparent strain or separation of the fabric weave with the new 'softer' material? The PD reserve manual is common to the Optimum & regular reserve, so there would be no change in tests done. Initial gut reaction is to be wary of 'lighter' fabric but of course the strength is supposed to be similar to regular fabric. Not that they publish specs, unlike for paraglider fabrics. I've only had to do a couple and was wondering what others were seeing. Quote Share this post Link to post Share on other sites
