Abstract Errors cannot be avoided in the process of machining and assembly because of the restriction of the manufacturing
ability, hence the assembly accuracy of products cannot be guaranteed. Different from the metal material, composite
material possesses anisotropy characteristics. Therefore, the control of the assembly accuracy of composite laminates
is more difficult. For the problem that it is difficult to guarantee the assembly accuracy of composite laminates, the factors
influencing the assembly accuracy of composite laminates was analyzed. After the parts machined in the same batch were
numbered and recombined with other parts, the effect of the combinations of different parts on the assembly accuracy was
analyzed using finite element method (FEM). For the assembly composed of multiple parts which can be assembled in different
orders, the effect of assembly sequence on the assembly accuracy was also analyzed. The research realizes that both
the different combinations of parts and the different assembly sequence have impacts on the assembly accuracy of the composite
laminates. Thereby, it is very important for improving the assembly accuracy of composite laminates to predict the
assembly accuracy and to optimize the combination and assembly sequence before the parts are assembled.
