|Summary||An automated system was developed for the design and manufacture of fibre reinforced plastic structures to substitute the high cost of labour in the current manual lay-up processes. This paper discusses the consolidation a proposed servo-controlled air-jet campaction system. The air-jet was designed and manufactured for use as a robot end-effector which provides an additional degree of freedom in the automated manufacturing of composite components made from prepreg and dry fabrics. This air-jet unit is computer controlled for precise vectorial and spatial positioning with respect to the tool used in the manufacture of a composite component. The focus of this paper is in the manual experimentation, which essentially simulates the proposed servo-controlled air-jet compaction system. The results, in terms of consolidation consistency, are presented with and without a process-aiding tangential force.
