Abstract
A method of fabricating a blade spar that includes transversely at least one arrangement. A pressure-side mold and a suction-side mold are defined for each arrangement that is to be fabricated. Each mold includes at least one removable slide and a base. Each slide is then removed from a mold and the tape segments of a hank are laid by a fiber-placement method on each mold. Each mold is closed by putting the slides into place on the mold. During a finalizing step, the molds are juxtaposed and the spar is heated.
