Building good usefull structures with "advanced Composites" like Carbon-fibre reinforced polymers is a Skill ... It must be aquired over a period of training, either on your own or through courses.
It helps immensely if you already have some skills in working with wood, metals or plastics. These skills will help you in making "Patterns", "Plugs" and moulds from existing parts.
To avoid costly mistakes, get some of the smaller "kits" from EC and make some small parts first, using straight forward wet-lay and compress the layup with bags of sand, hot water (speeds up the cure a lot), shrink tape or other ways of compressing the pieces you make.
I "trained" a lot using just glass-fibre weave -- saves a lot of expensive CF ...
Good luck!!
