- As you can see, things pulled apart in different directions.


Tried running this test 3 different times. Trying to hold on to the fiberglass was a bit of a trip.
Eventually, I rolled up each end like the above pic, that gave some substance to pinch between the pieces of plywood, trying to hold the ends there. - A couple more...


- Here are some interesting results from trying to pull fiberglass cloth apart.....

Sounds like a good idea to me!- PastorCharlieExplorerTest the raw cloth and reveal the added strength of epoxy or Por15
- Here I measured the thickness of the Epoxy coated fiberglass cloth.
It measures roughly .025 in thickness.
Then I also measured the thickness with the Por15 over fiberglass cloth.
This also measures about the same thickness at .025.
So, there is a little difference as to when it failed, although not a huge amount. The test setup could have accounted for some of that, by not being fully square.
Fortunately, I did not trash the new scale in these tests. That's a plus. - And then --- same as before with the Epoxy.

- Next step was to take a piece of fiberglass cloth, and coat it with Por15 this time, on both sides. Using the same setup like before.

This was also taken right before failure. Showing 405 lbs.
- And then .... BINGO!!!

- Ok, then. I finally got my testing apparatus fixed up again, since the new scale came in.
Here is a piece of fiberglass cloth - 1 single layer of cloth - with Epoxy resin covering it on both sides.
It is clamped in between pieced of plywood, which are hooked up to the bottom of the scale, and the bottom end, chained to a 2 x 3 to apply pressure.
This photo was taken at about the max pull weight, showing 455 lbs.
