Abstract: In-situ consolidation technology of continuous fiber reinforced thermoplastic matrix composites which means the parts manufacturing can be completed simultaneously could be achieved by AFP (Auto Fiber Placement) machine with the cost decrease of more than 50%.Due to its high efficiency and low consumption, the in-situ consolidation technology is considered to have wide application prospects in aviation field. The research and application of thermoplastic composite in-situ consolidation technology in aviation field at home and abroad were investigated. The current level of materials, equipment and process control on in-situ consolidation technology has been analyzed combined with the typical application of the technology. Meanwhile, the latest development trend of in-situ consolidation technology is also being stated.

Keywords: thermoplastic composites; in-situ consolidation; aviation; materials; equipment; process control
