Carbon Fiber Fabrication help
I'm making a carbon fiber piece that will hopefully be around a 4 inch by 4 inch by 5 feet tube that is a triple layer of 2x2 twill 6k tow carbon fiber (black picture) then 4 harness satin weave kevlar (yellow picture) then another layer of carbon fiber.
When I'm done this will be 5.62 pounds of material and epoxy resin at a 50:50 ratio.
Now it will actually have a pneumatic arm below it that will be lifting this carbon fiber arm and up to 5 pounds of piece for a total of 10.62 pounds being lifted.
So here are my questions:
When using wet lay up technique to make this carbon fiber piece, is it better structurally to make two halves from a mold and epoxy them together along a seem or to combine them along an overlapping?
Or is it better to use foam and lay the carbon fiber around the mold in a single piece?
Also, what is the best way to lay the carbon fiber if the force is downward? Is it that I lay the carbon fiber to where the fibers try and run down the part best they can will that give me the best strength?
Sorry for all the questions, but I'm confident that this forum is the smartest on this kind of stuff!
