ABSTRACT:
A sail batten formed of a fiber reinforced composite material extended longitudinally and varying in transverse cross sectional from an ellipse at one end to a flattened ellipse at the other end. A two step processing for fabrications the batten commences with fabrication of a tube of substantially constant cross section in the thermoplastic condition as a first step. The second step processing heats the tube to a malleable condition and squishes one end of the tube to form a tapered structure with one cross sectional dimension decreased to reduce stiffness in that dimension.
