ABSTRACT:
A composite ski pole is formed of fiber reinforced plastic laminates laid up around an inflatable bladder, and placed in a female mold. The bladder inflates to compact the laminates to substantially eliminate voids and form a smooth, hollow ski pole with a structurally strong and stiff skin. The molds may use compound shapes such as differing cross sections or longitudinal bends.
