Fracture behavior of low-density fibrous ceramicsA study has been carried out to characterize the fracture behavior of a particular class of silica tiles used in the thermal protection system of the Space Shuttle with emphasis on the strength distribution and time dependence of strength. The approach adopted is based on fracture mechanics concepts developed in recent years for the design of brittle materials. The study confirms that proof-testing and tile densification should lead to improved reliability of the thermal protection system. The research also suggests that the subcritical crack growth behavior of the fibrous tiles is similar to that observed in bulk glass of similar composition and that failure occurs by the tensile fracture and fragmentation of individual fibers.
