Static and Dynamic Testing of Interceptor Substructures.
Abstract
Truncated, conical, half-scale, interceptor substructures were tested under axial and shear/bend loads. The substructures, designed and fabricated by General Dynamics, were manufactured with 20 ply boron/aluminum composite tape, each ply was 0.0069 to 0.0080 inch thick. Boron filaments made up 47.0 + or - 3.0 percent of the composite tape. Average substructure dimensions were 5.80 inches (outside) forward diameter, 7.79 inches (outside) base diameter, and 9.112 inches high (total apex angle 12.46). The wall thickness was 0.144 inches. Axial loading (both static and dynamic) as well as shear/bend loading (static only) tests were performed; one sample was tested at each test condition. An upper bound to the failure load under static axial loading was estimated at between 600,000 pounds and 700,000 pounds. Under dynamic axial loading failure was initiated at a defect in the substructure and occurred at 519,000 pounds. Failure load in shear/bend was 44,000 pounds for the load applied laterally 1 inch forward of the truncated nose (bending moment of 383,300 in-lbs at the built-in section, 1.4 inches above the base of the cone).
