Abstract
Deformability and buckling load of yacht in fibers reinforced plastic sandwich
depend on the skins stacked sequence. In this work an optimization of the
laminae fibers direction of a competition yacht existing design is proposed.
This procedure has been divided into three parts (i.e. material characterization;
surface model definition; lay-up optimization). First of all a set of unidirectional
specimens has been realized, by using the same fibers and matrix (carbon/epoxy)
used for the hull as well as the same procedure and workers, in order to
characterize the material according to the ASTM D3039, employing strain gage
technique. In the second part, by means of an original software in Turbo-Pascal
(which uses the half-width value matrix as an input) linked to Pro/ENGINEER,
has been possible to obtain the body plan an
