摘要: 复合材料桁架结构具有重量轻、比刚度和比强度高、载荷分布合理的特点。为适应飞艇等浮空器的弧形曲面结构,创新设计了弧形三角截面碳纤维复合材料(CFRP)桁架结构,并对其制备技术进行了研究。桁架弦杆管件采用外模内加压的成型方式,三角腹杆与接头为整体结构、一体化成型,整体单元桁架在专用工装上组装连接。通过本方法制备的单元桁架组件比强度和比刚度大,各项性能满足设计指标要求,具有轻量化和承载性良好的特点。最终通过单元桁架组件的连接组合形成环形或弧形整体复合材料桁架结构件,可实现在飞艇、高空气球等浮空器桁架结构上的应用。

Abstract: Composites truss structure has the characteristics of light weight, high specific strength and specific rigidity and reasonable load distribution. In order to adapt to arc surface structure of airship and other aerostat, the arc triangular cross-section carbon fiber reinforced plastics (CFRP) truss structure was designed and its production process was studied. The truss chord pipe adopted the external mold and internal pressure forming, triangular web member and joint were integrative structure and integrated forming, and the integral unit truss was assembled and connected on the special tooling. The unit truss component produced by this method has high specific strength and specific rigidity, and its performance meets the requirements of design index, and has the characteristics of light weight and good load capacity. Finally, through the connection and combination of the unit truss components, the annular or arc integral composites truss structure can be formed, which can be used in the aerostat truss structure such as airship and high altitude balloon.
