Default Re: MIRO 2

Layed up the cowl today. This is the most tricky part due to its complex shape so I wanted to get it out of the way first. On the first model I had to add material afterwards to stiffen the part as I only used 1 layer of 75 gm glass and one layer of 75 gm Kevlar. This time around I am using S glass instead of Kevlar. S slass is 30% stronger and 15% stiffer than the usual E glass, I can feel the difference when cutting and handling it. The layup is an outer layer of 75gm E glass (for a nice surface) then 2 layers of 120gm S glass. You can also see I have put in a fillet of thickened epoxy in the corners of the flanges. I put the thickened epoxy into a ziplock bag and cut a little hole in one corner the squeeze it out like cake icing then smooth it off with my (gloved) finger.
