复合材料J型加筋壁板制造技术研究

对J型加筋壁板共胶接技术在实际应用中所存在的主要问题进行了研究,着重介绍了R区芯材精确填充、筋条外型模成型、框架式插销垂直定位、共胶接真空袋封装等关键技术的研究情况,并对相关技术的应用进行了深入分析。研究结果表明,在精确计算的基础上,设计制造专用成型模具可实现R区填充芯材的精确制备,有利于提高加筋壁板胶接质量;选用筋条外型模成型工艺,并设计采用框架式插销垂直定位装置,可有效解决J型筋的表面成型质量、筋条尺寸精度、位置精度等问题;使用已硫化橡胶作为维形挡条、制备合适的内型面软模、优化辅助材料铺放方法,可减少表面质量问题,降低架桥、破袋风险。在应用了上述一系列制造技术后,成功制造了满足使用要求的J型加筋壁板复材零件,并初步实现该类型零件的批量化生产。

Study on Manufacture of J Type Stiffened Panel Composite Material

This article studied the main problem of J type stiffened panels faced in the practical application, situation of application for some important technology, for example, the precise fill cor-material of R area, outer mold forming process of fillet, perpendicular positioning of frame-bolt type, assemble of co-cementing vacuum bag, have been introduced, and a deep analysis has also been done for the technique related. The experiment results show that, the cor-material can be made precisely with the precise calculation and the application for dedicated molds, by which, the quality of stiffened panels can be improved. With the application of outer mold and frame-type location device, the surface quality, dimensional accuracy, positional ac-curacy of J type stiffened panels will all be improved. Surface problem will induce with the use of vulcanized rubber for resist strips and suitable soft mode. With the optimizing of auxiliary material laying method, risk of bridging and bag broken will re-duce. By the use of all these technique introduced below, we successfully made the stiffened panels that can be used, this part can also be made bulkily.
