Evaluation of Syntactic Core Materials.

Abstract

Three syntactic core materials were evaluated: (1) HX501 epoxy/A24X glass microballoons, (2) HX501/Carbo-Spheres, and (3) HX592 bis-maleimide/A24X. After optimum B-staging and cure cycles were developed, the following core properties were determined: (1) density, (2) saturation moisture content (140 deg F/92% RH), (3) compressive strength, and (4) effect of thermal cycling on microstructure and water pickup. Sandwiched core panels were fabricated by cocuring B-staged core sheets between two face sheets of 3-ply graphite/epoxy.
