Technology of Cementing and Assembling Composite Truss

This paper describes the supporting conditions, technology and quality control, etc, in the process of
cementing and assembling truss of a certain model satellite which is made of carbon fiber composite. The research
shows that the truss has higher bonding strength when fitting clearance of rods and joints is between 0. 1 and 0. 3 mm.
The precision of truss is entirely depend on high-precision tooling, and ultimately precision can reach the accuracy of
0. 2 mm. Appropriate technological process and quality control method can satisfy the high precision of the carbon fiber
truss structure and cementing quality, and this method is also suitable for other products.
