摘　　要：对膨胀芯模法制备主承力复合材料管件的工艺原理进行了阐述,对工艺过程的关键环节进行了深入研究,并对该工艺制备的炭/环氧主承力管件进行了轴压强度实验研究。通过与相同材料体系制备的相同尺寸的缠绕管件的轴压强度和截面微观形貌的对比研究,表明膨胀芯模法制备的复合管件性能更好。The process principle of thermal expansion mould method （TEMM） was illustrated and the key process procedure was further studied. TEMM was utilized to fabricate the carbon/epoxy cylinders that were expected to serve in a large-load bearing thrust structure in the space delivery vehicle. Compared with wound cylinders which fabricated with the same materials and the same size, the axial compressive strength of the TEMM cylinders was much higher than that of the traditional wound cylinders. The micro appearance analysis also indicates that the solidity of TEMM cylinders is better than that of the wound cylinders.
