Abstract:

Fractography and analysis was performed on specimens of three dimensional quartz phenolic 3DQP, graphiteepoxy GE composite, and tape wrapped carbon phenolic TWCP materials. These specimens had been fractured under well characterized test conditions and the pretest condition of the materials was well known in all cases. The fractography was correlated with the test results to see what effect, if any, that testing at various strain rates and preconditioning of the materials had on the fracture appearance of these materials. The fractography correlated well with the test results. When a strain rate effect or a preconditioning effect was observed in the test results, there was also a different appearance in the fracture surfaces.
