Check Your 20 oz. Triaxial

1 Comment

Triaxial roving has had the same makup ever since I first heard about it. The 0 degree has the same weight as the combined weight of the +- 45s.
I have a 25′ daycharter cat being built in Seattle. The sample testing done by Gougeons gave very low results. And the burn test reveled that it only had 20% 0 degree fiber. No wonder the low numbers.
Orca has two different 20 oz. triaxial spec sheets apparently. Be very careful which product you get.
The one that I am used to has 354 gsm for the 0 degree and 200 gsm for each of the +-45s.
The other one has a 0 degree of only 142 gsm and +-45s of 292 gsm. each. That is clearly an inferior product but it is still called 20 oz. triaxial. Beware. First the bad one, then below, the good 20 oz. triaxial. I wonder who thought skimping on the 0 degrees would be smart?

Giant Vacuum Bags

These sealable mattress sized vacuum bags work great. You can put parts as large as a mattress in them, run the vacuum for a couple of minutes and seal it. The vacuum was still intact the next day. Unlike the Ziplock Spacebags.
