Abstract

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.
