Been learning about Nylon strengths and weaknesses. I know moisture isn’t as big of a deal as people make it out to be but was hoping for some advice/understanding on which type of nylon cf might be best for me.

So pa6 is strong as hell…but once it’s saturated it loses a ton of its initial strength.

To my understanding PA612CF15 retains way more strength when saturated.

This is with and without annealing. Either way you’re losing strength. So my question is. If you lived in a relatively humid environment… are you going PA6CF20? PA612CF15? PA612CF10 or PA12Cf?

    As I’ve pointed out before, at 5.3% moisture content (which you’re unlikely to reach even if you live on the gulf coast and store everything outdoors) the bending modulus of Fiberon PA6-CF is still 2286 MPa. That’s only 18% less than Polylite PLA Pro and 16% more than eSun PLA+. Impact strength significantly improves with moisture and tensile strength and layer adhesion don’t actually change that much.
