Abstract Aiming at the problems in the aerospace industry for a long time that curing process causes the size error
of composite part prepared in autoclave, assembly with stress and fatigue life is reduced. It realizes the match between
the two surfaces by the location coordinates of fiducial points, and presents a arithmetic of deformation modification and
a feasible means of correction by the study on the factors and mechanism of composites curing deformation. In the design
process of the forming die, a compensation for the surface of the forming die has been carried out, which reduces the trial
and amendment work of the die. It can realize the effective control of composites curing deformation and achieve the goal
of composites precision manufacturing.
