摘要：

The objective of this program was to develop preliminary mechanical design properties for brazed Rene'41 honeycomb sandwich. Strength data, creep data and residual strength data after cyclic thermal exposure were obtained at temperatures from 78K to 1144K ( minus 320 degree F to 1600 degree F). The influences of face thickness, core depth, core gage, cell size, and thermal/stress exposure conditions on the mechanical design properties were investigated. A braze alloy and process was developed that is adequate to fully develop the strength of the honeycomb core while simultaneously solution treating and aging the Rene'41 face sheets. New test procedures and test specimen configurations were developed to avoid excessive thermal stresses during cyclic thermal exposure.
