Abstract:

This report covers effort conducted under four tasks materials development design analyses breadboard studies and design of pre-prototype breadboard model. Materials development was directed toward refining the processing of polycarbonate materials, evaluation of raw polycarbonate resin and polycarbonate thermosetting coating materials and developing processing techniques for coatings. Design analyses have involved the development of theoretical and empirical data for fabricating lenses and programming the computer. Shapes and weights of each sphere, cylinder, and spherocylinder have been calculated and are being verified empirically. Breadboard studies have been directed toward mold and mold assembly characteristics and the development of a series of laboratory molding systems. Design efforts have been reducing the information generated in the previous tasks to a practical conceptual model, which will load to final design trade-offs.
