A fiber architecture in the form of an elongate beam having a hollow polygonal cross section with a plurality of substantially flat exterior sides and a corner between each pair of adjacent exterior sides. The cross section is substantially thicker adjacent each corner. The fiber architecture includes a first fabric layer extending around the beam, a layer of circumferential longitudinal rovings extending around the beam adjacent the outside of the first fabric layer, corner longitudinal rovings coterminous and integral with the outside of the circumferential rovings adjacent each corner, and a second fabric layer extending around the beam adjacent the outside of the corner rovings and adjacent the outside of the circumferential rovings not covered by corner rovings. The fabric architecture may be impregnated with resin to form a composite pole that may be used as a utility pole.
