复合材料捻子条自动化制造工艺研究

AUTOMATED MANUFACTURING PROCESS STUDY OF COMPOSITE RADIUS FILLERS

捻子条是复合材料梁肋三角区必不可少的填充材料。为了优化捻子条的制造工艺,提高制造质量,提高自动化程度,开展了材料构型、成型温度、材料填充数量等工艺参数的研究,探索不同的工艺参数对捻子条制造质量的影响。结果表明:材料填充数量为102%,拉挤成型温度为100℃,材料构型选取6. 35 mm×6层,可以保证捻子条的尺寸稳定、外观质量好。针对帽型长桁加筋壁板的捻子条,可以采用自动铺丝+拉挤成型工艺制造捻子条。采用优化后的捻子条可以保证蒙皮和帽型长桁的装配到位,固化后壁板三角区光滑过渡,质量好。

Radius fillers are indispensible part of filling material used in triangle area of composite beam and rib structure. To optimize manufacturing process, improve quality and enhance automatic level, the process study of material configuration, molding temperature and material filling quantity have been done to explore the influence of different process on quality of radius filler. The results show that the radius filler is of size stability and good appearance quality when the material filling quantity is 102%, molding temperature is 100 ℃, the material configuration is 6.35 mm×6 ply. Automated fiber placement and pultrusion process should be used to produce the radius filler of omega stringer reinforced panel. The skin and stringer can be assembled very well when the optimized process is used, and the triangle area of panel is smooth and of high quality.
