Radar transparent rigid polyurethane laminate systems for radomes |
| abstract |
A polyurethane-quartz laminate suitable for aircraft radomes. Controlled amounts of a mixture of unpolymerized 4,4 diphenyl methane diisocyanate (MDI) and 2,4 toluene diisocyanate (TDI) are polymerized with ethylene glycol at a preselected temperatures and periods to produce a polymeric resin of relatively few nonpolar isocyanate groups. The resin is impregnated and cured in layers of quartz cloth to form a relatively high strength composite or laminate having a low dielectric constant. |
