Abstract

The optical bench was designed using composite material, M40J/Cyanate Ester. Mechanical tests, thermal tests were carried out for M40J and structural vibration FEM analysis was performed. From the experimental results, the material properties of M40J/Cyanate Ester were obtained in longitudinal and transverse directions. By applying the properties into FEM vibration analysis, a proper stacking sequence was proposed for the laminated facesheets, so that natural frequency of the platform structure satisfy the design specification.
