With the increasing application of advanced composite materials in aviation,the forms of composite parts are gradually increasing and their applications are becoming more extensive.Frames are an important part of the aircraft,com-monly used as fuselage frames or other skeletal parts,which directly affect the accuracy of the shape and structural load-bearing capacity.The ingenious design of E-shaped composite frame have improved the level of integration of composite frames,avoiding the shortcomings of metal frames such as difficult processing and poor fatigue resistance.The structural characteristics of E-shaped frame are analyzed,based on the vacuum bag-autoclave curing process,the technical difficu-lites and key control points are elaborated.Relying on the scientifically design of molding tooling structure and meticulous control of the operational process,the E-shaped composite frames with excellent quality,recise external dimensions,and good appearance are successfully manufactured.
