ASTM WK73069

    New Test Method for Monotonic Axial Compressive Behaviour of Continuous Fiber-Reinforced Advanced Ceramic Composite Tubular Test Specimens at Ambient Temperature

    (What is a Work Item?)

    WK73069

    1. Scope

    This test method covers the determination of compressive strength including stress-strain response under monotonic loading of continuous fiber-reinforced advanced ceramic tubes at ambient temperature. This test method addresses tubular test specimen geometries, test specimen/grip fabrication methods, testing modes (force, displacement, or strain-control), testing rates (force rate, stress rate, displacement rate, or strain rate), and data collection and reporting procedures. Note that compressive strength as used in this test method refers to the compressive strength obtained under monotonic axial loading where monotonic refers to a continuous nonstop test rate with no reversals from test initiation to final fracture


    Keywords

    ceramic matrix composite; CMC continuous fiber composite; compressive strength; tubes

    Rationale

    Ceramic matrix composite (CMC) tubes are proposed for next generation of nuclear power reactors. Standards for mechanical behavior of CMC tubes in uniaxial tension and internal pressurization have been approved. New standards are required for flexure and compression.

    The title and scope are in draft form and are under development within this ASTM Committee.
