The Kevlar tow that I used is roughly an eighth inch wide. The tow
is basically a bunch of parallel fibers that are not bonded to each
other. While wrapping the spar, I have to take a little care to
spread out the tow and not get twists in it. Near the center of the
wing, the wraps should basically be continuous, i. e., touching each
other. Less wrapping is needed in the outer sections. On my
Majestic I wrapped the entire spar with nearly touching wraps.
Regards,
Dick
