摘　　要：介绍了非热压罐成型(OOA)低孔隙率复合材料技术的研究进展,详细阐述了OOA预浸料、OOA树脂再到OOA预浸料增强材料等对复合材料孔隙的影响,分析了OOA预浸料固化过程中影响孔隙的典型物理现象,以及各种制造工艺条件和参数等对孔隙率的影响,并提出了控制OOA复合材料孔隙率的方法和建议。In this paper,research progress of out of autoclave（ OOA） composite technology for low porosity composite was reviewed. We presented the influence of OOA materials properties including prepreg,resin and reinforcements on porosity of OOA composite,then,phenomena that affect porosity during curing were analyzed. Afterward,the relationships between porosity of OOA composite and manufacturing process conditions and parameters were also described. Finally,some suggestions on reducing porosity of OOA composite were proposed.
