ASTM C1337 Creep and Creep Rupture of Continuous Fiber-Reinforced Advanced Ceramics Under Tensile Loading

Scope:

The test methods in ASTM C1337 can be applied on all possible composites of ceramic matrix with all unidirectional, bidirectional, and tridirectional continuous fiber reinforcement. Additionally this test procedure can also be extended on glass matrix composites, again with all unidirectional, bidirectional, and tridirectional continuous fiber reinforcement. Although not intended yet, the methods in ASTM C1337 can be applicable on whisker-reinforced, fiber-reinforced, or particulate-reinforced ceramics.

Test Procedure:

The test procedure in ASTM C1337 is influenced by test rate, test mode, elevated temperatures, environmental influences, alloying effects, and processing for evaluating any nonlinear stress-strain behaviour. Often these effects are also a result of corrosion or subcritical crack growth. It is of importance that the ceramic materials creep more relatively when subjected to tension compared to compression.

Sample size:

The methods in ASTM C1337 use various test specimen geometries. The values obtained from standardized tensile tests indicate the material response from which they were primarily processed after subjecting to heat treatments.

Data:

The test method results expressed in ASTM C1337 follows the International System of Units (SI).

Conclusion:

Creep and creep rupture test methods described in ASTM C1337 determine deformation of continuous fiber-reinforced ceramic matrix composites as a function of time when subjected to uniaxial tensile stresses at higher temperatures.
