ABSTRACT:
Radially extending fibers are disposed over a conical surface at predetermined sites. The sites correspond to vertices of a pattern of contiguous congruent squares inscribed onto the surface of a sector of a circle which may be conformally mapped into the conical surface. Vertices of the pattern coincide along the join line meridian of the conical surface. Fibers are disposed along element paths between the radially extending fibers and preferably, a continuous fiber is used. The material obtained is without any seams or discontinuities and exhibits an invariant fiber volume fraction along the axis and circumference of the conical surface. The material may be used to reinforce an object having a conical surface or to fabricate a preform.
