SERVICES TO GENERATE BASIC ENGINEERING DATA ON THE BEHAVIOR OF PLASTIC COMPOSITE STRUCTURES UNDER VARIOUS CONDITIONS OF STRESS
Abstract
Three 7-in.-diam pressure vessels and D-ring specimens were fabricated. Two of the pressure vessels were tested. One failed at 1195 psi and the other at 1600 psi. The same wrappings were used in both cases except that a perforated Mylar pressure wrap was used on the case which failed at 1195 psi and a solid pressure wrap was used on the other. High circumferential wrap tension (0.76 lb/per end) was used on both cases; the technique was improved on the second case to produce bet er quality.

Aug 61, 40p. incl. illus. 24 refs. (Contract AF 49(638)167) (AFOSR-1303)Unclassified report DESCRIPTORS: (*Shock waves, Argon, Krypton, Xenon, Gases, Gas ionization, *Plasma physics.) (Spectrographic analysis, *Ultra violet radiation.) (Recombination reactions, Electrons, Ions.) A study was made of the radiation emitted by the ionized rare gases Ar, Kr, and Xe. These gases were formed in reflected shock waves in which the equilibrium temperatures ranged from 7,500-12,000 K and t e electron densities from 10 to the 15th to 10 to the 18th power per cc. The intensity of the continuum radiation which is emitted throughout the visible and ultraviolet regions reached a steady state value some distance behind the reflected shock wave which corresponds to the equilibrium region predicted for the shock wave.
