Abstract: For the filament winding of negative Gaussian curvature surface such as transition section between shell and nozzle of solid rocket engine,the general criterion for fiber bridge on concave revolution surface winding is derived based on differential geometry theory. The winding path on several transition section surface is discussed. An experiment demonstrated the correctness and practicability of the criteria.It showed that the winding path on uniparted hyperboloid is steadier than on concave ring surface and the winding angle on ruled surface is just the critical angle of no bridge. For smooth motion the hypervelocity point canceling and data-filtering are needed.
