“…Additionally, Flint et al [24] and Flint and Lindler [25] presented a novel self-supporting membrane shells approach; then, Footdale and Murphey [26] and Footdale et al [27] proposed a related nonplanar hybrid deformablesegmented surface support structure with quadrilateral reticulations. A square shape carbon-fiber-reinforced polymer shell was investigated by Keil and Banik [28] and Fernandez et al [29], which can be used as a candidate surface for the hybrid deformable-segmented surface support structure proposed by Footdale and Murphey [26].…”

A novel, rollable, singly curved, parabolic shell reflector and its nontrivial shaping method were developed. The rollable shell reflector was a monolithic thin rectangular plate with linearly varying thickness, and it was able to roll up elastically around a mandrel. A system of end moments and loads was used to shape the linearly thickness-tapered plate into a parabolic cylinder, and a mathematical model was deduced to predict the shape accuracy of the thin plate based on nonlinear beam theory. A certain parabolic cylinder reflector was analyzed by the proposed shaping method. The optimized shape accuracy agreed well with the simulation result, and it was able to meet the precision requirement. The proposed shaping method provided a promising technology for enabling a high-precision parabolic cylinder shell reflector with different apertures.
