Abstract:

This program has as its objective the determination of the feasibility of fabricating polypropylene armor radomes. These radomes are required to provide protection for radar antennas from a Level II fragmentation threat. Four inch thick PP armor will be required to meet this threat level. The plan was to develop processes based on the present state-of-the-art technology to fabricate four inch thick spherical radome sections, and to investigate edge-to-edge joining of flat polypropylene armor panels. The thick spherical molding are beyond the present technology and will require a new tooling and production approach. The present technology is limited to one inch thick flat panels. The manufacture of several four inch thick radome shell sections with a 60 inch spherical radius established the feasibility of this approach. These panels were submitted to the Naval Research Laboratory for performance evaluation. Adhesive and fusion bonded edge-to-edge joining methods were also developed. The systems evaluated indicate the feasibility of obtaining structural joints of PP armor panels. Author
