Millimeter and sub-millimeter wave observations, however, which largely depend on the instrumentation techniques,
provide vital experimental verifications for the theoretical studies of stars formation. To obtain the stronger and more
precise radio spectrum signals, high precision reflector panels that are demanded in great amount especially for the large-aperture
antenna and antenna-array. Many years, experts have put emphasis on the precise forming of reflector panels.
This paper presents the high-precision panels with a sandwich-type construction of one skin-plate and one aluminum
backup structural combined with structural adhesive, with high precision modules as the fundamental condition. The
skin-plate fit the module well due to its flexible. The structural adhesive, with good flow-ability, automatically
compensate the deviations between the skin-plate and the backup structural. In the end, individually shaped sandwich-like
panels assemble up the high surface-accuracy reflectors. The internal stress analysis of skin-plate and structural
adhesive are of utmost importance. Therefore, several kinds of skin-plate and structural adhesive in different material
properties are listed and simulated with finite element method (ANSYS). Based on the simulation results, processing
parameters to panel fabrication are determined more efficient and accurate.
