hi guys, new to the composites world and have a few questions, hope you's dont mind.
1. carbon kevlar aramid fabric, is it stronger than normal carbon fabric? ignoring the inflated price what benifits does it provide over just plain cf? what is it like in a crash, does it crack and shatter the same way as cf?
2. some terms i have seen thrown around, "twill" and "2 twill" thats the weave type right? is "twill" suitable for auto panel making, i have seen elsewhere most use 2twill. also 2k,3k,6k, that refers to the density if each weave, the amount of strands?
3. soric sf2, i noticed this being used in the "how to make a bonnet" tutorial, am i right in saying that it doesnt compress? that would seem to be a problem for me, where a bonnet or q-panel skin might only be .8mm, adding a 2mm layer of soric doesnt seem like the best idea, where and why is it used?
4.im investing in a bulk order of 50m x 1.5m of carbon/kevlar fabric from china. i saw in some tutorials many different weights used, in the bonnet tutorial he used 200g and 600g fabrics, i dont want to have to order two or three types of rolls, do you think a 400g per m/squared is ok for making automotive panels?
or, the supplier says he can get me a 200g roll of carbon kevlar 1.5m x 50m and a 600g 1.5m x 50m roll of just carbon for about 15%less per roll. if you guys think using just 400g is unsuitable i might go for the second option.
i do have more but cant think of any right now. thanks for taking the time to read ppl, looking forward to your replies
