Abstract：The automated fiber placement (AFP) technology is gaining importance in advanced manufacturing of low-cost and high-performance composites. In order to improve the layup quality based on the compression response and tackiness of prepregs, this paper reviews recent development on the deformation and bonding mechanisms of uncured prepregs over a wide range of processing conditions as well as the AFP process induced defects and effects on mechanical behavior of composites at home and abroad. The research efforts in the future are probably going to focus on the development and related scientific problems of the mechanical behavior of AFP-related composites.
