Nondestructive tests for determining braze bond quality of open face honeycomb seal rings, using low viscosity liquids with fluorescent additives
Hexagonal and nonhexagonal cell phenolic honeycomb design as energy dissipating material noting processing, composite constituents, cell configuration and usage environment
Lap-shear strengths of Mg-Al alloy bonded with nylon-epoxy adhesive, including anodized coating rolling schedule and honeycomb core fabrication
Cookie cutter device initiates production of identical, double-contoured fiber glass elements used as shock absorbers. Three-bladed edges convert triangular honeycomb elements into hexagonal shapes which are then stamped to desired length by concave and convex dies. Sandpaper smoothing completes the process.
Vertical steel tubular pins restore the shear strength of honeycomb panels and improve the quality of the repaired panel. New repair method eliminates diagonal pins. Vertical pins are welded to face sheets, forming ''Vierendeel Truss'' arrangement to transmit shear loads.
