Since this thread is light years from it's origin ..........
Kevlar is good stuff, but carbon fiber is awesome. I saw a 34' boat, a couple weeks back, that two buddies imported from Dubai (built there). It is going to be rigged with two billet 3.5 liter custom built "Mercurys", making 460+ hp each, and will attempt to break the twin outboard world speed record. It is a two seat cockpit boat, and at 34' it only weighs 1700 lbs., unrigged. All carbon fiber. Buddy said if it doesn't break 140 mph on the first good pass he will be really surprised. Looking for north of 150 after dialing it in.

I just had to repair a corner on a 31 year old plastic fairing for a Japanese motorcycle, Stan. I cut about a 1 square out of the remains of a MN. State Troopers bulletproof vest. Soaked it in epoxy I thinned with lacquer thinner, and laid it over the crack. I had worked some into the crack before I thinned the stuff to go into the Kevlar.
Bulletproof vests have a date code on them, and Troopers are required to get new ones when the old one goes out of date. My Trooper neighbor and I took it to the range, and put it on a hay bale, and had at it. It stopped every handgun round we had access to, save one.
A lowly 30 caliber CZ52 that was fed sub gun ammunition, hitting about 1700fps.
Turns out the thing was designed for shooting through cars at checkposts
He said he was impressed. Im really careful where use the gun.
Best,
