Description
The radiation response of a base-line carbide composite (SiC/SiC) made with Nicalon trademark CG fiber reinforcement was presented for a broad range of dose and irradiation temperatures. Strength loss in this composite and a similar composite made with Tyranno trademark fiber was related to shrinkage and a predicted mass loss in the Nicalon CG or Tyranno fibers. In Table 1, measured relative density and length changes (Δp/po and ΔL/Lo, respectively) for coated and uncoated fibers irradiated at high doses and temperatures (43 dpa-SiC at 1000 C and 80 dpa-SiC at 800 C) are given. Also given are the relative mass loss changes Δm/mo, calculated from Δp/po and ΔL/Lo by the expression Δm/mo = 3 ΔL/Lo + Δp/po
