As I mentioned in my initial message, woven materials are not desirable in stiffness-critical structures.
The resin/fibre ratio with RTM is lower than prepregs. This means they are heavier.
being a materials engineer, aside from the marketing hooey. is Time's RTM lay up "better" than a normal cloth with a higher resin fiber ratio?
I have heard that it is and typically lasts longer before it goes dead...
I ask in all sincerity as someone who is looking for new frame but not interested in "lightweight and stiff" for racing but "compliant, strong and efficient" for longer distance riding and longer life of the frame.
My preference would be Titanium, custom by Tom Kellog, but I have an eye on a certain pre-owned ride...
