1. The lifetime of a composite material having a dispersed filler has been examined under conditions of low-cycle compression. 2. It has been shown that, in distinction from materials of fibrous structure, the lifetime of this material is determined, not by a breakdown in the continuity of structure, but the deformability of the polymer matrix. 3. The absence of a correlation between the static and fatigue strengths of composite mateials from cold and hot curing is caused by the different effect of the structure of the cured binder as a component of the material on the ultimate static characteristics and creep, whose relaxation character is more clearly expressed. 4. Creep of the binder and the strength of the microspheres are the main factors which determine the lifetime of the material in question in cyclic compression. [ABSTRACT FROM AUTHOR] |
