Hi Ken
I have made a few full kevlar fuselages and my experience is that it is strong and light. I have not experienced any problems with the resin fabric matrix. The issues I have had are just the usual ones, you need aramid scissors and it can't be sanded easily. Fully wetting it out is an issue too as it doesn't take the wet look of glass.
I suppose I could have used the 80 gm carbon instead but it is very expensive and there is the RF issue so I just used it for local reinforcement. I could make it neater and also improve the resin to fabric ratio. All in all this would have to be one of my best fuselages
