Involute (Rosette) Bodies
Involute construction is a popular approach that has been used for the past twenty years in the rocket motor industry for the fabrication of exit cones and other bodies of revolution by lamination of composite layers along curved trajectories, called involute surfaces. The approach was initially developed for use in ablative plastic liners where structural capability was only a minor issue. Consequently, no disciplined efforts were undertaken to examine the relationship between the mechanical response and the known properties of the basic composite material. In the 1970’s however, involute construction became predominant in the fabrication of carbon-carbon structural bodies so that mechanical response characteristics assumed critical importance.
