Manufacturing Methods and Technology (MM and T) Project to Establish Production Techniques to Manufacture Rigid Armor for Radar Antenna Hardening
Abstract
This program is being conducted to establish production techniques and production capabilities for manufacture of plastic armor panels intended to provide ballistic protection for flat radar antennae. Technical fabrication problems were reassessed and subscale process development initiated to solve these problems. Subscale panels, fabricated during the period, demonstrated progress in the elimination of several of the processing problems. Overall panel opacity, surface delaminations, and voids or trapped air were brought under control. The reduction of preconditioning temperatures to less than 180 F and a reduction of the lamination time eliminated the opacity problem. Application of a woven polypropylene fabric as protective face plies eliminated the surface delamination or non-lamination problem on the limited number of samples fabricated this period. The utilization of silicon sponge rubber seals improved the degassing efficiency and evacuation capabilities during processing. Minimal voids or air entrapment were the result. The process revisions required to accomplish the above were defined.
