给出了金属纤维增强钍的几种物理性能的数值。在室温下测定的性能包括抗压强度、断裂模量和杨氏模量（动态方法）。在高温下测定的这些性能包括断裂模量、杨氏模量、导热系数、热膨胀和抗氧化性。与单独的thoria相比，增强thoria中广泛存在的细裂纹导致其强度显着降低。增强钍的导热系数在室温下略大于钍的导热系数，在高温下差异更加明显。(认证)
Values were presented for several physical properties of thoria reinforced by metal fibers. Properties determined at room temperature include compressive strength, modulus of rupture, and Young's modulus (dynamic method). Those properties determined at elevated temperatures include modulus of rupture, Young's modulus, thermal conductivity, thermal expansion, and oxidation resistance. The widespread presence of fine cracks in reinforced thoria results in significantly lower strengths compared with thoria alone. The thermal conductivity of reinforced thoria is slightly greater than that of thoria at room temperature, and the difference becomes more pronounced at elevated temperatures. (auth)
