Abstract
A cornerstone of structural integrity is the proper use and characterization of structural materials. Improper materials characterization or use of a material system outside its designed use range (intentionally or unintentionally) can have perilous results for structural integrity. As gas turbine engines and other applications drive toward higher operating temperatures for structural elements, the materials characterization and design allowable generation activities become increasingly difficult. We discuss elevated temperature testing requirements and the development of testing solutions aligned with these requirements. Mechanical testing systems for elevated temperature testing for polymeric matrix composites (PMCs), metallics, and ceramic matrix composites (CMCs) were developed. Test capability for temperatures as high as 1500 °C was demonstrated. The development of these systems will be briefly reviewed with particular focus on design aspects, system performance, and general usability of a system targeting testing of cylindrical metallic specimens at temperatures up to 1200 °C.
