    摘要:

    拉挤杆缝合高效一体化结构(Pultruded rod stiffened efficient unitized structure, PRSEUS)综合利用了复合材料的一体化缝合和整体固化技术,能够满足翼身融合布局民机的传载、止裂、稳定性和维修性等结构设计要求。PRSEUS面板采用了低成本整体式结构设计制造方法,通过采用三维编织、单边缝合和可控气压树脂灌注等技术,完成纤维编织、缝合和树脂灌注过程,以低温共固化和缝合技术确保结构法向强度。通过合理选材和工艺设计,易于满足翼身融合布局民机不同部位结构的多样性设计需求。本文从翼身融合布局民机PRSEUS结构选材设计、PRSEUS结构制备核心工艺、PRSEUS工装夹具、典型PRSEUS测试壁板制造和典型机身试验件制造等方面系统阐述了翼身融合布局民机PRSEUS结构制造工艺技术的最新进展和发展现状,通过总结与展望PRSEUS结构制造工艺研究进展,为中国未来民机结构设计制造以及新型材料结构研发提供有价值的技术参考和研究方向。

    Abstract:

    Pultruded rod stiffened efficient unitized structure (PRSEUS) can meet structure design requirements of load transmission, damage arresting, stability and maintainability in hybrid wing body (HWB) civil aircraft by combining composite material integrated stitching and co-cure technique. Comparing with existing composite material manufacturing technique, the manufacturing of PRSEUS panel uses integral structure design method at low cost to complete the process of fiber knit, stitching and resin infusion by applying knit machine, one side stitching and controlled atmospheric pressure resin infusion technique. Moreover, the additional out of surface strength is enhanced by co-cure at low temperature and stitching technique. The diverse design requirements of different position structure panel design in HWB structure are satisfied easily by reasonable material selecting and process design. In this paper, latest developments and current techniques of HWB civil aircraft PRSEUS panel manufacturing technology are presented from aspects of HWB civil aircraft PRSEUS structure material selecting design, PRSEUS structure manufacturing core process, PRSEUS structure fixture and clamp, representative PRSEUS test panel manufacturing and representative fuselage article manufacturing. Thus, by summary and prospect on research progress of PRSEUS structure manufacturing technique, the research here provides valuable technical reference and research direction for design and manufacturing of civil aircraft structure and development on novel material structure of our country in the future.
