Wrapping wood in carbon fibre. Answered
After cutting my own wooden lacrosse shaft using the tutorial on Instructables, it snapped within half an hour of use. Now I know this was because the grain was pretty poor and it was not a strong wood, but someone suggested that I wrap a shaft in carbon fiber so that it is slightly stronger, limits horizontal movement and reduces denting.
I just have a few questions about trying this;
Would this carbon fiber be appropriate for the project. http://compositeenvisions.com/raw-fabric-cloth-2/carbon-fiber-97/carbon-fiber-fabric-plain-weave-3k-5-7oz-tape-605.html if not where should I look?
The biggest problem I see is somehow packing the carbon tight around the shaft so there are no bubbles and it is consistently straight all the way down the shaft, there is a vacuum packing basics tutorial on instructables but I'm not sure if you could use that for a lacrosse shaft. Instead of making my own bag as per tutorial would just a plain bag (http://compositeenvisions.com/vacuum-infusion-equipment-71/nylon-vacuum-bagging-film-500.html) be fine then clamp off the unneeded extra, although are those bags re usable? Because I don't want to have to pay $5 USD every time I would like to wrap something. I saw something called bleeder cloth as well, would this be needed to stop excess resin sticking to the shaft?
When it comes to the carbon, I know someone who sails a lot and has some experience with carbon fiber but none with vacuum packing who said I should lay it up like the image attached to decrease horizontal movement while allowing vertical flex. Would this have the desired affect as if this is successful I plan to make a ton more for a high school team I help coach. I've attached a image to give you some idea of what I'm talking about.
Then for the actual laying of the carbon itself, a shaft is not a flat surface so you can't just pour it on like the Youtube video's I've found. I'm not sure how to pull this off.
Then afterwards, is there a simple way to test the properties of the shaft; specifically flex and impact strength. Because even if I don't end up wrapping the shafts I still need to test the wood to compare it to alloy.
Sorry about the small essay, but I would really like to give this a good shot. Because shipping shafts from the states is quite expensive, being able to make my own and then put graphics on them would be amazing.
