Changing weldment to fiberglass composite (composites being completely new to me) and was hoping to get a couple things sorted out in my head:
1) I'm using mil-p-25421, type ii, class I, cloth base #181 for my ply's. I want as few ply's as possible but the part will be secured using 1/8"...
Mechanical Metallurgy by Dieter also has a good basic chapter on fatigue testing and the ins and outs. Other than that maybe the TMS website has some books for materials engineers. There are pifalls to be aware of regarding fatigue testing, and this is also why it is a highly researched topic...
