Manufacture of 30 Fibre Preforms 23

variety of high technology items, such as: golf clubs, aircraft propellers, yacht masts and
light weight bridge structures (Popper, 199 1). Thick, multilayered preforms can be
manufactured through traditional 2D braiding, but the processes of 2D and 3D braiding
and the variety of possible preforms that can be manufactured using these techniques
are generally very different.
