摘要

Embrittlement temperatures of composite propellants,at nominal uniaxial strains of 5, 10and 25per cent,have been measured by two bending beam methods,and the results compared statistically with interpolations from WLF master curves of rupture strain in tension against log reduced strain-rate. Effective strains are deduced which place the majority of the embrittlement temperature values within the scatter of the WLF master curves. It is concluded that the relatively simple embrittlement tests yield measurements of the strain at rupture no more variable than those derived from a similar number of uniaxial tensile tests.
