If structural failure of the fabricated composite occurs by cracks in the matrix, fracture of the particle-matrix interface, or case debonding under any applied load, the extra and exposed surface will cause an enormous rise in the motor pressure during the combustion event with disasterous consequences. 

The examination of this model and results of numerical solutions indicate that ignition propagation is determined by the absolute value and variation of heat transfer along the surface of the grain, both before and after the first instant of ignition on the grain surface. Therefore, the important variables are (1) igniter flow rate, (2) port diameter, (3) gas temperature, (4) gas composition, and (5) motor pressure.

During the extrusion of specimens, speed of the extruded specimen, current of the auger screw motor, pressure at the die and pressure at the depressurized room were measured. After extruded, the hardnesses of formed specimens were measured. 

The seal (or protector) operates, as its name implies, to provide a barrier between the well-base fluids and the motor. The seal is normally multi-chamber and is additionally designed to equalise the internal motor pressure and to enable the motor insulant to either expand or contract.

The Fault Tree Handbook, Chapter VIII, has an excellent example of how to construct a fault tree of a pump-motor pressure system, as shown in Figure 7.5. The handbook describes the problem (Roberts et al., 1981).
