Has anyone had any success bonding 300D HyperD to 1.1oz Silpoly? I've currently got a couple of test patches curing but would like to know of any issues I should be aware of.
Edit: Appears to bond OK after 24hrs curing. Would the difference in stretch between the two be a problem in the same way as reported when stitching?

i think it would be an issue if you use the bond for reinforcement, if you just use it to interface two pieces of something, it should be fine (so if you don't expect the two bonded pieces to "work together" but rather "pull eachother along", should be fine). apparently even for tarp reinforcements, except for really extreme loads, the difference is not big enough to be visible in use, but otoh, the tarp reinforcements are exactly for the extreme loads.
I asked RBTR and their response was:
I'll go with the 1.1 silpolyIf you are going to glue patches on, we highly recommend using the same material as the body. The HyperD 300 is PU coated, and while the Silnet may adhere initially, it's not a strong bond.
For the HyperD 300 patches, we recommend sewing them on.

After reading through things here you seem to have all you need.
However,you have a head start because if the sail design aspect.
Sails have higher loading stresses and especially momentary loading.
Sails are generally made to a higher standard than a tarp.
Your theory on reinforcement patches in the same orientation is spot on.
