Abstract
A structure obtained by laying filaments on a convex axisymmetric surface to provide a hemispherical surface. The structure may include with a circular hole or a dead zone centered on an axis of the surface and may be formed by laying filaments along a geodesic path. The structure includes a first and second part, in which the first part includes the axis. The geodesic path formed by the filaments on the first part may be spaced a predetermined distance the opening or circular dead zone.
Claims11
A structure comprising:
- at least one convex axisymmetric surface including at least one of a circular opening and a circular dead zone centered on an axis of said convex axisymmetric surface;
- said convex axisymmetric surface comprising a casing covered by filaments bound by a settable binder, said filaments including one of single filaments and sets of filaments;
- said convex axisymmetric surface including a first and second part defined by a circle, said circle including a center positioned on said axis of said convex axisymmetric structure, said first part including said axis;
- said filaments laid onto said first part along geodesic paths at a variable spacing from said at least one of the opening or the circular dead zone and laid onto said second part along geodesic paths so that said filaments cross each other;
- and
- said at least one of the opening or the dead zone not being covered by said filaments.
