A's paper is an excellent starting point. Also look at this thread

The construction method in A's paper is not the only way to make such a structure. As shown above, you can fully wrap the nose and over bond the trailing edge. You also have the choice of an internal or external mandrel. In your situation, for making just a few pieces in a school project, a extractable steel mandrel is too expensive to machine, as is an expanding internal bladder. You can use a multi-piece extractable, machinable PU tooling board or a wash-out salt mandrel, but these are labor intensive. The quickest, dirtiest way is an internal foam mandrel (or "core") that you leave in when done.(This is the method championed by Uncle Burt.) This requires very skilled layup (and an external caul plate) to get a nice external surface finish and not have ply wrinkles. But it does add some weight. PM me if you want detailed advice.
A's paper mentions loss of performance due to fabrication imperfections. In the case of buckling critical parts, the 0 degree buckling resistance can be improved by using pultruded graphite rods in the layup. These eliminate any manufactured-in wrinkles in the 0 direction fibers. They are commonly used in very high aspect ratio structures, such as sailplane wings
Have fun and learn a lot with your school project! As part of my Masters thesis, I did design, analysis, fabrication, and materials testing of a little missile fin.
[edit] Don't put aluminum fittings directly against plies with carbon fiber. There is a severe galvanic corrosion problem.
