Autoclave is one of the most impor-tant manufacturing processes commonly used to fabricate composite structures with high performances in aeronau-tical and aerospace area. If the cure process is not well controlled, the defects, such as uneven fiber distribution, bridging, waviness, delamination, and deformation, will occur, which seriously affect surface quality, mechanical properties and reliability of composite parts. The pressure monitoring technology during the autoclave process is an important experimental method to guide mould design, cure cycle optimization and the mechanism analysis of de-fect formation, and to improve the manufacturing capabil-ity of composite structures. In this paper, the test methods and their suitability of the pressures shared by ifber, resin, and prepreg stack during the autoclave process are summa-rized.
