Can someone give me the strengths of KR fiberglass, The carbon fiber glass and the Kevlar. Comparing weight to strength. Has anyone used Kevlar, it is a tad cheaper than carbon fiber and said to be stronger and lighter than carbon fiber. for the 5OZ it has a tesile strength of 620X655. Can someoen explain that to me? I want to know the difference of that and normal 5.85 KR cloth. Justin KR2S Justin, just use the door skin plywood from Home Depot....

It is young fellows such as yourself that keeps aviation going when us old farts are all gone. Mind you, I am only 47 so I plan on being around for quite some time. You remind me of my oldest son when he was 16, full of questions and never satisfied with a simple answer and always wanting to reinvent things. Well, my oldest son is now 26 and an Engineer Graduate of Georgia Tech, with honors I might add. I am told you are 16 to 17 years old and I think you are on track to being a great addition to the aviation world. There have been a lot of flames against you for asking questions which have obvious answers or easy sources to find the answers. For those who have flamed you, I think you deserve an apology. For those who have helped you, they need to be thanked. For those who were just picking at you...well, I hope they remember what it was like when they started aviation and especially building a plane. And, I am willing to bet none of them were 16 when they took on such an enormous task as building an airplane. Justin, keep asking your questions, keep learning, keep progressing and one day we will all be patting you on the back for doing such a good job. Never give up on your dream, and never let your dream give up on you. Keep it up and make us all proud to be associated with such an inquisitive mind. I see another engineer in the making!!!

The results are simple. The weight savings for the entire airplane will be aprox 7lbs and abotu 4X the cost. The entire airplane's fiberglass is around 25 but around 18 with carbon fiber. That seems a minal weight difference to pay 4X as much. If im missing something could I be cleared up. I know Mark L has used carbon fiber for his wings and other parts.
