COMPRESSIVE STRENGTH OF CONOLON 506 AT +75F AND -320F,
Abstract
The ultimate compressive strength of Conolon 506 increases from 39,200 psi at +78F to 57,100 psi at -320F. Typical failures at +75F and -320F are shown. Modulus of elasticity values in compression also increased as temperature decreased. Room temperature modulus values were 3,600,000 psi while at -320F, the modulus increased to 3,990,000 psi. Maximum strain values at ultimate averaged from 10,998 micro-inches at room temperature to 13,978 micro-inches at -320F. Figures show a plot of stress vs. strain for five separate runs of Conolon 506 at room temperature and -320F. Note the absence of any secondary modulus of elasticity at both temperatures. Mechanical property data at +75F and -320F is shown. Specimens no. 2 and no. 4, which were tested at -320F, failed in end bearing. This was attributed to the fact that the fixture had to be reversed because the attachment of the lead wires was different. (Author)
