Zusammenfassung:	An automated fiber-placement method comprises delivering a first quantity of pulsed energy to first portions of at least one fiber-reinforced tape strip, and delivering a second quantity of pulsed energy to second portions of at least the one fiber-reinforced tape strip, alternating with the first portions. Each one of the second portions at least partially overlaps two adjacent ones of the first portions such that overlapping regions of the first portions and the second portions have a higher temperature than non-overlapping regions of the first portions and the second portions. The automated fiber-placement method further comprises laying down at least the one fiber-reinforced tape strip against a substrate along a virtual curvilinear path, such that (i) at least the one fiber-reinforced tape strip is centered on the virtual curvilinear path, and (ii) the overlapping regions are transformed into discrete tape-regions, geometrically different from the overlapping regions.
