If you mean "laminated fiberglass" in the sense of a laminated fiberglass recurve bow, there are dozens of resources on the web that can teach you that. The 'loose laminate' fiberglass that comprises the prod on my avatar crossbow is not glued together, just lightly held together like old fashioned leaf springs.
I've never worked with carbon fiber, personally. Much too expensive for my blood.
Dimensions of prods, tillers, bolts, actions depend upon the desired draw weight of the prod you want to build, the materials you want to use, etc. Give us some specifics and we can probably help. If you're just starting out, a good resource are the "replacement fiberglass prods" available on Ebay in 50#, 80# and 120-150# draw weights.
We're not really a "tell me everything I need to know" kind of place. But we will help you once you've done some research and decided upon the rough dimensions and specifications of your first build. Read into the discussions here. Read the Building Wiki referenced on the right side of this page. Then ask us some pointed questions, not vague generalities, please.
