使用单纤维拉伸试验评估了从复丝带中提取的 Bi2223 长丝的杨氏模量和拉伸断裂强度；估计它们分别为 106 GPa 和 45 MPa。断裂强度的分布可以使用威布尔分布函数进行分析。结果发现，与 NbTi 和 Nb3Al 等其他超导丝相比，观察到的强度分散非常大。杨氏模量与基于卸载/重载模量的混合规则的估计值几乎相同。
The Young's modulus and the tensile fracture strength of Bi2223 filaments extracted from multifilamentary tape have been evaluated using the single-fibre tensile test; they are estimated to be 106 GPa and 45 MPa, respectively. The distribution of the fracture strength can be analysed using the Weibull distribution function. It was found that the observed scatter of strength is very large compared with other superconducting filaments such as NbTi and Nb3Al. The Young's modulus was nearly identical with the estimated values based on the rule of mixture from the unload/reload modulus.
