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

What is ASTM C1337? 

ASTM C1337 is used to measure the time-dependent deformation (creep) and time-to-rupture of continuous fiber-reinforced advanced ceramic matrix composites under constant tensile loading at high temperatures. The test method in ASTM C1337 (Standard Test Method for Creep and Creep Rupture of Continuous Fiber-Reinforced Advanced Ceramics Under Tensile Loading at Elevated Temperatures) can be applied to all possible ceramic matrix composites with all unidirectional, bidirectional, and tridirectional continuous fiber reinforcement. Additionally, this test procedure can also be extended to glass matrix composites, again with all unidirectional, bidirectional, and tridirectional continuous fiber reinforcement. Although not intended yet, the methods in ASTM C1337 can apply to whisker-reinforced, fiber-reinforced, or particulate-reinforced ceramics.

ASTM C1337 Sample Preparation Guide

The method in ASTM C1337 uses 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.

What are the Test Procedure and Requirements of ASTM C1337? 

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 behavior. Often, these effects are also a result of corrosion or subcritical crack growth. It is important that ceramic materials creep more under tension than under compression.

Analysis Result and Interpretation

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