Despite the fact that composite materials have excellent comprehensive properties and are widely used in modern aircraft structures,their structures often suffer from local excessive stress and even structural damage during the assembly process due to their large forming deviation and weak inter-laminar performance.In order to ensure the integrity and mechanical performance of composite assembly structure,it is of necessity to conduct in-depth research on the assembly mechanical behavior of composite structure,while the geometric shape of the structure meets the accuracy requirements.This paper analysis the influence of assembly process on assembly stress of composite structure,summarizes the research on assembly mechanical behavior from the aspects of sizing and clamping,gap compensation,bolt connection,etc.,and proposes further research prospects.
