Im looking to have several gas powered scooter parts made in carbon fiber from a cad file. Such things as steering pole, rims, deck, air scoop, and a distant goal of a frame. scooters in question www.goped.com. I understand some basics of carbon fiber, but pretty much just what you can learn from watching too much TLC. Im working on the steering poles right now, and where the pole will mount to the frame it will be through two sandwhiched pieces of aluminum bolted up securely. The upper part however, is where i am hesitant. Im going to make a billet Aluminum part that will have a cylinder that will slide into the cf shaft, then the outer aluminum shell (still the same billet part) will slide over the cf shaft but this time from the outside-so the cf is sandwhiched. I will have threaded holes tapped into the machined aluminum part, then drill some holes in the cf and bolt the aluminum part to the cf shaft, which will (i believe) be secure because of the compression of the two aluminum layers pressed against the cf. My questions are, is there a more effective method of bonding cf to Al? Will this kind of bond i have described result in a point of weekness below the Al part? The shaft will be about 3.75 feet tall and as i said used on a gas powered scooter ranging anywhere from 19mph to 60+mph, what kind of cf should i specify to ensure that it is safe for riding street and also for riding off of ramps and other instances where the steering pole would be stressed. This kind of thing has been attempted before with cf, but it failed because the cf would break and nearly impale the riders. Where they have failed, i will succeed. Any suggestions on this amazing material would be appreciated.
