Techniques for testing whether a bond strength between a faceskin of a panel and a core of the panel exceeds a threshold value are disclosed. The testing includes: adhering a first surface of a sacrificial layer to a pull stub of a flatwise tensile (FWT) test apparatus by way of a first adhesive interface; adhering the second surface of the sacrificial layer to the panel faceskin by way of a second adhesive interface; operating the FWT test apparatus so as to gradually increase a FWT load on the faceskin; terminating the test upon the first to occur of separation of any one or more of the first adhesive interface, the second adhesive interface, the sacrificial layer and separation of the faceskin from the core; and determining that the bond strength exceeds the threshold value when separation of the faceskin from the core is not the first to occur.

An air-supported sandwich radome with a hemispherical top region and a prolate region has a high strength, RF transmissive, low dielectric flexible wall. There is a defined region where damaging RF radiation is reflected. At least in the defined region, a flexible high strength, RF transmissive low dielectric layer is added and there is a low dielectric gap between the wall and the layer providing a 180&#xb0; phase delay between RF energy reflected off the wall and RF energy reflected off the layer to cancel the effect of said reflected RF energy on radar equipment housed by the radome.
