True to form you were bullshitting and when called out you can't back off, so you predictably have no alternative but to continue in the same vein.
It is the only "vein" I have! You are asking for a calculation I did a decade ago. Do you honestly think I could provide that documentation to you?
C'mon, irie mon, its the holidays and you and I are both weeding out those brain cells we dont really need via some good drink. So you have an excuse for not comprehending the situation.
But why go on with zero contribution to this thread? And what contribution would my 10year old calculation add here. We can just do it again. And what if my old or new calculation was off by 10 - 20 percent???? Does that mean everything I say is a lie? What if I say the sky is blue and Kevlar is terrible in compression? Are those not true statements even if a parrot is saying them? (Yes, I give you permission to call me a parrot, because we all are as the equations we use were not created by any of us here)
Honestly, I am barely recalling that the information I found when I was having Kevlar compressive failures. I think it told me compressive strength of Kevlar in the layups i was using was like 45 percent of its tensile strength. And now I am reading its 30 - 10 percent of tensile strength??? So now I am even confused! But what I am clear on is when I was using s-glass with a layer of Kevlar to "toughen" the surface against heel dents, the numbers showed it was no better than just the s-glass. And since I am finding out that it seems to be even weaker in compression than the information I had back then.....well, it does not change the decision/realization that calculation gave me.
So once again, happy holidays, and knock back a few for me. I'm heading out on 10+ days of snowkiting. But I'll be back here hoping you have cheered up.
