Messing round with boats is fun !! the learning never stops ,even after more than 30 years there's always something new happening somewhere ! BUT somethings never change and some problems never go away and just keep reoccurring !!so moved into Composite Forensics , Now that something completely new !!

Tunnels, I have been reading this thread and am a bit overwhelmed with the many paths boat builders are using to make their products. You stated that CF is too brittle for boat hull construction. I was having a conversation with an almost world champion F1H2O boat driver (soon to be, I hope!)who was telling me that his and the other F1 boats were almost all CF, with the exception of the capsule. I questioned him, based upon what I know about CF being brittle and he said, no, they are definitely CF. Your thoughts on this? I know that my Skater has Kevlar layup where the hull is capped and at the bulkhead to hull juncture. That makes scene to me! Skater also offers a "CF layup" option, but I do not know where it is used. Your thoughts are appreciated.

Not looking to dispute your post as you seem to know way more about this stuff than me or the average guy. However just the other day I was watching the Lucas Oil Drag Boat series on TV and they did a shot inside of Brian Sanders Top Fuel Hydro capsule and what did I see but a carbon/kevlar weave on the walls. These guys have a huge budjet and can afford the best of everything so maybe this stuff wasn`t just for the 80`s & 90`s. Looks like they are still using it.

Used on my current build along with foam penske board and new urethane resin, first in the US.

yip its still used but a lot of research and development has gone on since those early days !, different weaves different percentages of each material even the materials themselves have changed and there are different grades that we never had long ago ! Kevlar and carbon are used together so if one fails the other is there as support ! Hard and brittle Carbon and soft and tough Kevlar so during a crash its a double safe guard .
I have noticed very recently that there are new more flexible grades of carbon that could find there way into the industry ! I haven't seen any test results but maybe Kevlar could get replaced !. Lots happening in the research and development field for aircraft and automotive applications and needs so eventually could find it way into the marine industry as well !!Last edited by tunnels; 01-10-2017 at 07:52 PM.

Carbon/kevlar
Tunnels you are right about technology. It never stops. New stuff coming out year after year.
